ZoomInfo is the name most sales professionals know. 

It dominates the B2B sales intelligence platform space. But ask yourself: do teams pick it because it’s the best option, or just because it’s the brand they’ve heard of?

Plenty of ZoomInfo alternatives can do the job better. 

Some offer cleaner verified contact information and stronger data quality. Others stand out with flexible pricing plans, fresher company data, or extras like buyer intent data.

The point is simple:

If your sales and marketing efforts depend on reliable contact and company data, you need to know your options. 

This guide walks through 15 proven alternative to ZoomInfo tools that help companies build healthier sales pipelines without overpaying.

I’ve compared them on 8 practical criteria:

• Coverage & Match Rates – how much usable contact data and company data each has

• Pricing Transparency – published costs, contract flexibility, and value per contact
  
  

• Data Quality – bounce rates, accuracy of direct phone numbers, and verification
  
  

• Ease of Use – setup speed, user friendly interface, and workflow
  
  

• Integration Capabilities – CRM sync, sales engagement tools, and marketing automation tools
  
  

• Compliance – GDPR, data security, and providers prioritizing data security
  
  

• Unique Features – buyer intent data, technographics, and niche functions

• User sentiment: We reviewed G2, Capterra, and Reddit feedback to see what actual users like and dislike. This helps separate hype from real value.

Below is a quick TL;DR comparison table to help you size up Zoominfo alternatives worth considering in 2025 👇

Quick rundown: Top ZoomInfo Competitors in 2025

Why Organizations Seek ZoomInfo Alternatives

ZoomInfo has strong B2B sales intelligence features. But many sales and marketing professionals still look for ZoomInfo competitors. The main reasons come down to coverage, cost, data quality, and usability.

Coverage Limitations

ZoomInfo’s single-source database usually finds only 40–50% of contacts. Sales teams targeting startups, technical roles, or global markets run into gaps fast. After GDPR, its European data dropped further. 

One user put it bluntly: “I've found zoominfo to be really poor since GDPR for EU Data.” Weak global data coverage makes it harder to run consistent outreach efforts and sales strategies.

Pricing Structure

The median annual contract value is over $15,000, and deals often drag through long negotiations. Some companies spend $72,000 a year once extra tools are added.

For most sales and marketing teams, that’s a huge barrier. What they want are clear pricing plans that flex with actual use — not rigid seat-based models.

Data Quality Concerns

Reviews often mention outdated data and bounce rates of 15–20%. Phone numbers and job title info are common pain points. 

One team reported 21% bounces for three months straight before switching providers. For teams where every lead matters, shaky data accuracy can break a sales pipeline.

Integration Gaps

Even with its size, ZoomInfo isn’t seamless. Its API and export features are limited. The steep learning curve and crowded interface frustrate small teams. 

As one G2 reviewer put it: “So many features, it’s hard to find time to learn them all." That complexity slows down sales professionals instead of helping them.

Top 15 ZoomInfo Alternatives in 2025

1. FullEnrich: Waterfall Enrichment for Maximum Coverage

FullEnrich pulls from 15–20 premium data providers, giving sales teams broader contact data coverage. Its waterfall data enrichment method checks multiple sources in sequence, hitting 85%+ match rates and boosting lead generation efforts.

What teams really like is the lightweight setup. Instead of spending weeks onboarding like with enterprise suites, you connect your CRM & GTM stack (Salesforce, HubSpot, Clay, Zapier, Make, n8n) or upload a CSV.

That way, you get enriched data back in minutes. The credits system is clear, bounces are minimized thanks to triple verification, and you’re not stuck with annual lock-ins.

Ease of Use

Setup is fast. API integration with major CRMs takes 15–30 minutes. The intuitive user interface removes the steep learning curve you see with larger platforms. Users describe it as “pleasant, easy to handle, and lightweight,” especially for bulk data enrichment at scale.

Pricing

• Starter: $29/month (500 credits)

• Growth: $55/month (1,000 credits)

• Scale: Custom pricing

• No annual contracts required

• Pay only for successful enrichments

Key Features

• Waterfall enrichment across 15-20 premium providers

• Triple-verified contact and company data

• Real-time validation ensuring accurate data

Bottom Line:

Best for growth-stage B2B sales teams who already have engagement tools but want maximum verified contact data.

2. Apollo.io: All-in-One Platform for Small Businesses

Apollo.io has become the go-to all-in-one tool for SMBs, thanks to combining a comprehensive database of 275M+ contacts with built-in sales intelligence tools.. Instead of juggling three different tools, small teams use Apollo as their one-stop shop.

More than 15,000 customers and 50,000+ weekly users make it one of the fastest-growing ZoomInfo competitors.

The appeal is the convenience: you can find contacts, send emails, make calls, and even score leads in the same dashboard. The Chrome extension lets you pull prospects from LinkedIn and sync them straight to Gmail or Salesforce. It’s simple enough for a small team to pick up quickly, though some users flag bugs as new features roll out.

Ease of Use

The user friendly interface needs little training. The Chrome extension makes LinkedIn prospecting quick. Apollo ranks No. 1 for ease of use on G2, though some users mention bugs that disrupt outreach efforts.

Pricing

• Free plan: 50 credits/month

• Basic: $49/user/month (2,500 credits)

• Professional: $79/user/month (4,000 credits)

• Organization: $149/user/month (6,000 credits)

Key Features

• Built-in sequencing and dialer for outbound sales efforts

• Extensive contact database with verified email addresses

• Lead scoring and buyer intent data

• Workflow automation with sales triggers

• AI writing assistant for personalization

• Advanced search filters for targeting

Pros & Cons of Apollo.io

User Sentiment

G2 Rating: 4.7/5 on G2 (9,049 reviews)

Users love Apollo.io for its ease of use, verified data, and fast outreach tools.

Luis C., Head of Marketing and Sales, shared:

"I have been using Apollo.io’s lead enrichment and email sequencer tools for some time now, and I like their efficient design (not too minimalist, not too crowded)." (Source)

However, some reviewers mention occasional bugs in automation and outdated contact info.

Anam A., RevOps and CRM Specialist, added:

"Phone numbers mentioned on Apollo are usually outdated.” (Source)

Bottom Line

Ideal for sales and marketing teams of 10–50 people. Apollo offers affordable, all-in-one sales intelligence with some trade-offs in global data quality.

3. Cognism: Premium European B2B Data

Cognism is known for GDPR-compliant contact data and strong European coverage. Their Diamond Data® provides human-verified direct phone numbers with 98% accuracy, making it a favorite for sales professionals targeting the EMEA market

Unlike ZoomInfo, which has had coverage issues in Europe post-GDPR, Cognism gives every contact an opt-out trail and permission status.

That means fewer compliance headaches and less risk of outreach fines. The trade-off? Pricing is closer to ZoomInfo than SMB-friendly platforms like Apollo.

Ease of Use

The platform has a professional interface with advanced search capabilities. The Chrome extension (via Kaspr) supports LinkedIn prospecting. Setup takes some training, but it ensures teams use compliance features correctly.

Pricing

• Platform: ~$15,000/year

• Enterprise: $25,000+ annually

• Most plans include unlimited exports and Diamond Data®

Key Features

• Diamond Data® verified mobile numbers

• Built-in GDPR compliance with audit trails

• Partnership with Bombora for intent data

• 400M+ global contacts with firmographic data

• “Do Not Call” suppression for 13 countries

• Chrome extension for real-time prospecting

Pros & Cons of Cognism

User Sentiment

G2 Rating: 4.6/5 on G2 (1,095 reviews)

Cognism is praised for its accurate contact data and smooth CRM integration. 

Diva G., Associate Business Development Representative, shared:

"As a BDR, what I like best about Cognism is the quality and accuracy of the contact data—especially the direct dial numbers, which significantly increase my connect rates." (Source)

But some users mention issues with outdated info and occasional mismatches in phone numbers.

Rezaul H., Sales Development Representative, added:

"I haven’t received any notifications after submitting contacts for Diamond verification, so I’m unsure how reliable or responsive that feature is." (Source)

Bottom Line

Best for sales and marketing teams targeting Europe who need verified, compliant contact and company data. Higher cost, but unmatched for quality data and compliance.

4. Clearbit (Now Breeze Intelligence): Real-Time Data Enrichment

After HubSpot’s acquisition, Clearbit was rebranded as Breeze Intelligence. It specializes in instant data enrichment and strong company data insights, especially for marketing teams.

It’s less of a “data warehouse” and more of a marketing automation booster. If you’re already a HubSpot customer, it feels native. But it won’t work standalone; non-HubSpot users can’t access Breeze.

Ease of Use

It works seamlessly inside HubSpot with automatic enrichment. Its API-first design suits technical teams, though standalone functionality is limited. Non-HubSpot users may face integration hurdles.

Pricing

• Available only through HubSpot

• ~$12,000–$30,000/year depending on volume

• No standalone pricing

Key Features

• Real-time form enrichment for lead generation

• Website visitor identification from company websites

• Rich company details and technographic data

• IP-to-company matching (Reveal)

• Custom audience building for ads

• Slack alerts for target high value accounts

Pros & Cons of Breeze Intelligence

User Sentiment

G2 Rating: 4.4/5 on G2 (626 reviews).

Clearbit is valued for its precise firmographic data and straightforward access to executive insights.

Stéphanie M., Marketing Director, shared:

"Amazing free version allowing you to set your ideal client profiles and target audiences and to keep track of website visits.." (Source)

But some users note it performs best when paired with other tools, especially for deeper prospecting.

Anubhav N., RevOps and Inbound Marketing Manager, added:

"I wish there were more options in the ICP definition. Very few criteria right now." (Source)

Bottom Line

A good choice for HubSpot users focused on inbound marketing. Not ideal for sales teams who need verified contact data or work outside HubSpot’s ecosystem.

5. LinkedIn Sales Navigator: Social Selling Platform

LinkedIn Sales Navigator taps into 900M+ profiles for relationship-driven selling. More than 1M businesses use it for B2B sales prospecting.

Ease of Use

The interface feels familiar since it’s still LinkedIn. Advanced search filters help narrow down prospects, while TeamLink shows warm paths to key decision makers. Its biggest strength is constant updates — job title changes and employment data refresh in real time.

Pricing

• Core: $99/month

• Professional: $119/month

• Advanced: $149/month

• Advanced Plus: $179/month

Key Features

• Real-time employment updates from 900M+ members

• TeamLink relationship mapping

• InMail messaging (50–150 per month depending on plan)

• Account and lead recommendations

• Job change alerts

• CRM integration for tracking

PROS and CONS of LinkedIn Sales Navigator

What Real Users Say About LinkedIn Sales Navigator

G2 Rating: 4.3/5 on G2 (2,011 reviews)

LinkedIn Sales Navigator is often praised for its advanced search filters and up-to-date prospect data.

Vaibhav U., Sales Representative, shared:

"One thing to specially mention is it's wide variety of filters which helps me in reaching out to specific contacts and companies filtering out the non relevant ones." (Source)

However, some users feel it lacks deeper analytics and requires layering with external enrichment tools.

Aman S., Senior Business Development Associate, added:

"You cannot easily get the contact details of the users." (Source)

Bottom Line

Best for sales professionals focused on relationship-based selling. To get full value, pair it with data enrichment services that provide verified contact data.

6. Lusha: Simple LinkedIn Prospecting

Lusha helps with quick LinkedIn contact discovery through its Chrome extension, serving 1.5M users with a free plan and low-cost upgrades.

It’s popular among SDRs and founders who want something quick, simple, and affordable - without getting locked into an annual $30K contract.

It’s not trying to be an all-in-one platform like ZoomInfo or Apollo. Think of it as a tactical tool: open a LinkedIn profile, click, and get an email or number.

It works, it’s cheap, and it’s easy to set up. But it won’t scale well if you’re running large outbound operations.

Ease of Use

The extension works instantly on LinkedIn profiles. Setup takes less than five minutes. The user friendly interface keeps things simple: “minimal learning curve” according to G2 reviewers.

Pricing

• Free plan: 5 credits/month

• Pro: $29/month (50 credits)

• Premium: $69/month (200 credits)

• Scale: Custom pricing (600+ credits)

Key Features

• One-click LinkedIn Chrome extension

• 100M+ business profiles in its extensive database

• Domain search for company websites

• Direct phone numbers and verified email addresses

• Sales intelligence tools and buyer intent data

• CRM integration for instant export

• Credit rollover (up to 2× monthly limit)

Pros & Cons of Lusha

User Sentiment

G2 Rating: 4.3/5 on G2 (1,535 reviews)

Lusha stands out for its ease of use and reliable contact data, especially for LinkedIn-based prospecting.

Kanika M., Sales Manager, shared:

"Lusha in the contact finder that provides contact information of sales prospects, company history & background of the company, where you would get the contact information by installing the extension & adding to LinkedIn profile." (Source)

But some users report outdated or inaccurate US contact info and find the credit limits restrictive.

Donna C., Sales Development Representative, added:

"It has certain limitations on the data it gives, particularly invalid emails or contact numbers, as sometimes they are inaccurate." (Source)

Bottom Line

Good fit for individual SDRs doing LinkedIn prospecting. Teams needing full sales intelligence or data accuracy at scale should look at other ZoomInfo alternatives.

7. Seamless.AI: AI-Powered Search Engine

Seamless.AI claims a database of 1.3B contacts with AI-driven verification. But many users report problems with data accuracy, raising questions about reliability.

On paper, it looks like a budget-friendly ZoomInfo alternative with the promise of unlimited leads and unlimited users.

In practice, reviews show it’s a mixed bag: some teams find great contacts, others complain about bad numbers and pushy sales reps.

Ease of Use

The AI-powered search feels new but can be inconsistent. The Chrome extension works, but advanced features come with a steep learning curve.

Pricing

• No transparent pricing

• Requires sales conversations

• Reports of aggressive contracts

• Often $79+/user/month

Key Features

• AI-powered search with natural language

• Real-time verification claims

• Chrome extension for prospecting

• Intent data signals

• Unlimited search options

Pros & Cons of Seamless.AI

User Sentiment

G2 Rating: 4.4/5 on G2 (5,123 reviews).

Seamless.AI is praised for its large contact database and user-friendly experience, helping sales teams build lead lists fast.

Kat K., CEO, shared:

“The amount of data you can grab instantly is incredible. It saves me hours of research and makes prospecting much more efficient.” (Source)

But some users report inconsistent data quality and occasional duplicates that require manual cleanup.

Sebin M., Sales Lead, added: 

“I would say that the data of Asian and Indian countries are very less comparing to the American and Europe region. (Source)

Bottom Line

A high-risk choice. Worth testing with a free trial before committing. Accuracy concerns and contract terms make it a cautious pick for sales and marketing teams.

8. Lead411: Unlimited Access Platform

Lead411 offers true unlimited exports and claims 96% deliverability thanks to triple verification. It’s built for high-volume B2B sales teams who need verified contact data.

The trade-off? The database is smaller than giants like ZoomInfo, but the contacts you do get are usually cleaner because of their triple verification process.

Ease of Use

The interface looks dated but is functional. Search and export are simple. Responsive customer support makes up for the older design.

Pricing

• Basic: $75/month (unlimited exports)

• Pro: $99/month (with buyer intent data)

• Enterprise: Custom pricing

Key Features

• Unlimited exports (no credit system)

• 40M+ triple-verified contacts

• Bombora intent data integration

• Growth and sales triggers

• Firmographic data tracking

• 96% email accuracy guarantee

Pros & Cons of Lead411

User Sentiment

G2 Rating: 4.5/5 on G2 (467 reviews).

Lead411 is well-liked for its accurate and easy-to-access contact data, helping sales teams boost outreach productivity.

Peter J. A., IT/MSP Sales Account Executive, shared:

“It has a simple UX, so there is minimal learning curve... very strong sorting (company size/$, titles, employees, geo-area/zip codes, etc.) to create targeted lists. You can also filter to ensure that the contacts you select have direct dial and mobile tel #'s. (Source)

But some users have flagged issues with outdated contact details and limited filtering features for targeting specific regions.

John L., President, added:

“The revenue filtering options could be improved to better fit various industries. (Source)

Bottom Line

Excellent value for US-focused sales professionals doing high-volume prospecting. Perfect if you prioritize quality data over polished design.

9. UpLead: Quality-Guaranteed Data

UpLead promises 95% data accuracy and refunds credits for bounced emails. It’s built for sales and marketing teams that want verified contact data they can trust.

Ease of Use

Clean, modern design with strong search filters. The credit system is simple but needs monitoring. A free trial with 5 credits is available.

Pricing

• Essentials: $74/month (170 credits)

• Plus: $149/month (400 credits)

• Professional: $199/month (1,000 credits)

• Monthly or annual billing

Key Features

• 95% accuracy guarantee with automatic refunds

• Real-time email verification

• 50M+ contact database

• Technographic data included

• Intent data signals

• Company details enrichment

Pros & Cons of UpLead

User Sentiment

G2 Rating: 4.7/5 on G2 (803 reviews). 

UpLead is frequently praised for its ease of use, verified contact accuracy, and helpful customer support, making it a reliable option for lead generation. 

Dionard D., Sales Development Representative, shared:

“I find Uplead user interface intuitive making it easy to use for lead generation. Also, I've read great reviews online about data accuracy, around 95% I believe.” (Source)

Some users report outdated or missing data, which can limit outreach effectiveness.’

Jerry C., President, added:

“Complex searches with large datasets sometimes slow down on older, slower systems.” (Source)

Bottom Line

Perfect for marketing teams that value accuracy over volume. Pricier per contact, but better deliverability makes up for it.

10. RocketReach: Professional Contact Finder

RocketReach claims 700M+ profiles, strong for technical roles, and is often seen as an alternative to ZoomInfo for finding key decision makers.

Think of it as a lightweight way to grab verified contacts without committing to a heavy price tag compared to platforms like ZoomInfo.

Ease of Use

Simple browser extension. Functional bulk lookup. API well-documented for developers.

Pricing

• Essentials: $48/month (125 lookups)

• Pro: $108/month (300 lookups)

• Ultimate: $249/month (1,000 lookups)

Key Features

• 700M+ claimed profiles

• Browser extension for quick lookups

• Bulk processing

• Strong international coverage

• API access

• Social profile aggregation

Pros & Cons of RocketReach

User Sentiment

G2 Rating: 4.4/5 on G2 (987 reviews)

RocketReach earns praise for its accurate contact data, user-friendly interface, and consistent ROI for outbound efforts. 

Kartik C., Senior Sales Manager, shared:

“I was unsure about getting a subcription until i convinced my Hotel to buy me one. As i work in sales, it help me finding sales pitches and connect directly with people. I recommend everyone taking the email and phone subcription as it saves time both for you and your company.” (Source)

Users frequently mention challenges with outdated information and find the pricing high for smaller teams.

Thomas D., President, added:

“In many cases I will receive an email and the person has recently changes jobs. They still have the old email.” (Source)

Bottom Line

Good for global email lookups. Less reliable for direct phone numbers. Best fit for teams needing affordable email discovery.

11. Kaspr: European LinkedIn Extension

Kaspr, now part of Cognism, helps with fast LinkedIn prospecting in Europe using a Chrome extension.

It doesn’t try to be a full sales suite - it’s a focused tool that does one thing really well: turning LinkedIn into a direct contact finder.

Ease of Use

One-click setup for LinkedIn. Very lightweight, minimal setup.

Pricing

• Free: 15 contacts/month

• Starter: €45/month

• Business: €65/month (unlimited emails, 100 phones)

User Sentiment

G2 Rating: 4.4/5 on G2 (827 reviews)

Kaspr stands out for its ease of use and reliable lead generation, offering quick access to accurate contact data that supports outbound efforts. 

Vivek D., Senior Manager, shared:

“I like the ease of use and higher accuracy in getting the contact details especially email details of the prospects” (Source)

But some users note that pricing can be confusing, and limited credits or missing features may restrict advanced prospecting needs.

Jake B. Sr., Account Executive, added:

“Kaspr bases everything off of REGULAR LINKEDIN URLS ONLY, which are impossible to scrape or access. It nearly impossible to do any sort of bulk enrichment and I'll explain why as I've basically wasted my subscription on Kaspr due to these issues.” (Source)

Bottom Line

Best for SDRs doing LinkedIn prospecting in Europe. Narrow scope, but excellent within that niche.

12. Snov.io: Email-Focused Outreach

Snov.io blends email finding with built-in outreach tools, making it a solid budget option for sales and marketing efforts.

It’s not as data-rich as some actors in the space, but if your workflow is heavily email-based, it’s an affordable all-in-one setup for smaller teams.

Ease of Use

All-in-one platform for prospecting and sending campaigns. Easy setup, limited advanced features.

Pricing

• Trial: $0 (50 credits)

• Starter: $39/month (1,000 credits)

• Pro: $99/month (5,000 credits)

Key Features

• Email finder and verifier

• CRM integration

Pros & Cons of Snov.io

User Sentiment

G2 Rating: 4.6/5 on G2 (453 reviews)

Snov.io earns praise for its intuitive platform and powerful cold email tools, with many users highlighting its ease of use and responsive customer support. 

Murtaza P., Demand Generation Manager, shared:

“Snov.io is a one-stop solution for running cold email campaigns end-to-end. As someone who has handled all cold outreach for years, It's great how everything is in one platform - finding leads, verifying emails, building sequences, sending multi-step campaigns, and tracking responses —all from a single dashboard.” (Source)

However, some report missing features and limitations in email campaign customization, especially when scaling outreach.

Adam F., Founder, added:

“Lack of integrations, complicated system, over engineered.” (Source)

Bottom Line

Great for small sales teams doing outbound sales efforts by email. Not enough for those who need a full sales intelligence platform.

13. Dealfront: European Website Intelligence

Dealfront (formed from Leadfeeder and Echobot) focuses on European B2B data and website visitor identification.

nstead of just giving you a list of names, it shows you which companies are visiting your website and ties that back to real business data.

For teams in Europe (especially in the DACH region) it’s positioned as a compliant alternative to ZoomInfo with a different angle: catching warm leads while they’re already browsing your site.

Ease of Use

Setup requires some technical work for tracking. The interface is more complex than pure sales intelligence tools.

Pricing

• Entry plans start around €99/month

• Custom packages range €10,000–30,000/year

• Pricing split across modules

Key Features

• Identify anonymous company websites visitors

• GDPR-compliant EU database

• Intent data from site visits

• Strong coverage in the DACH region

Pros & Cons of Dealfront

User Sentiment

G2 Rating: 4.5/5 on G2 (111 reviews)

Markus T., CEO, shared: 

“Dealfront is incredibly comprehensive and easy to use. We use it across the entire group, and it's become an integral part of our sales process. (Source)

While the tool performs well in core functions, users note some drawbacks like limited advanced features or occasional accuracy concerns in niche markets.

Katja P., Marketing Coordinator, added: 

“I don’t particularly enjoy the credit system limiting the exports of the contacts, it feels like more workI don’t particularly enjoy the credit system limiting the exports of the contacts, it feels like more work to think about how to make the best use of them.” (Source)

Bottom Line

Great for European companies that need website intelligence with GDPR compliance. Limited if you’re after broad global lead generation.

14. LeadIQ: Salesforce Workflow Optimizer

LeadIQ simplifies LinkedIn-to-CRM workflows, especially for Salesforce teams without the copy-paste grind.

If your reps live in LinkedIn Sales Navigator, this tool takes the pain out of prospecting by syncing everything directly into your sequences and avoiding manual entry.

Ease of Use

A Chrome extension lets you grab contact details from LinkedIn in one click and sync them straight into your CRM.

Pricing

• Freemium: 20 credits/month

• Starter: $45/user/month

• Pro: $89/user/month

Kushal A., Business Development Representative, shared:

“The sync feature with the CRM and Sales tools like outreach and salesloft help focus more on the money making activity.” (Source)

However, concerns around data accuracy, especially invalid emails and phone numbers, remain a common theme in user feedback.

Atish B., SDR, added:

“Sometimes I feel it’s not up-to-date because the prospect contact details are inaccurate or the numbers are invalid.” (Source)

Bottom Line

Best for Salesforce-heavy teams running outbound sales efforts. Not broad enough for teams needing deep data enrichment.

15. PeopleDataLabs: Developer-First Data API

PeopleDataLabs (PDL) offers massive contact and company data via API. It’s built for technical teams building custom solutions.

Instead of giving you a polished interface with filters and dashboards, it provides developers raw access to 1.5 billion profiles worldwide through APIs.

That means you can build your own enrichment workflows, plug data into your product, or power internal tools with massive amounts of employment, education, and firmographic data.

It’s not built for SDRs or marketers - it’s built for engineers who want flexibility.

Ease of Use

Requires developer skills. The API is well-documented, but there’s no simple UI for non-technical users.

Pricing

• Free: 100 API calls/month

• Starter: $98/month (350 credits)

• Growth: $500+/month

• Enterprise: Custom

Key Features

• 1.5B profiles worldwide

• Full job histories and firmographic data

• Skills and education fields

• Bulk enrichment API

• Custom data models

Pros & Cons of PeopleDataLabs

User Sentiment

G2 Rating: 4.6/5 on G2 (16 reviews)

Users appreciate PDL’s deep and accessible B2B dataset and responsive support that eases adoption.

John Z., Director of Data Products, shared:

“People Data Labs has managed to build an extremely extensive data platform with their innovative data co-op approach. The applications that can benefit from this resource are uncountable and really only bound by their creators' imaginations.” (Source)

On the flip side, some point out a steep technical learning curve and occasional inaccuracies tied to LinkedIn-derived data.

Joseph H., Enterprise Customer Success Manager, added:

“There are some data quality issues. For example, the data seems to trust LinkedIn a bit muchWould be great to have a higher match rate.” (Source)

Bottom Line 

Ideal for companies with dev teams that want raw verified contact data. Not usable for non-technical sales professionals.

Frequently Asked Questions

Who is ZoomInfo's biggest competitor?

Apollo.io has quickly become the main challenger. With 15,000+ customers, 50,000 weekly active users, and rapid growth, it delivers sales intelligence tools at a fraction of ZoomInfo’s cost. 

That said, the “biggest” depends on your lens. 

LinkedIn Sales Navigator has the widest reach with over 1M business users, while Cognism leads in Europe with GDPR-compliant contact data and 98% accurate direct phone numbers.

Is ZoomInfo or RocketReach better?

For large sales teams, ZoomInfo usually wins. It offers stronger data accuracy (85–90%), richer buyer intent data, and more account based marketing features. 

RocketReach is cheaper and useful for finding key decision makers in technical roles, but its accuracy hovers around 70–80%. ZoomInfo is the better all-rounder; RocketReach suits budget-conscious sales strategies.

Apollo is the better bet for small and mid-market sales and marketing teams. 

At $49–149/month, it includes sequencing and a dialer, so you don’t need extra sales engagement tools. 

Accuracy runs closer to 85%, but users say the savings are worth it: “For 5% of the price, I’ll take a few bounces.” ZoomInfo works best for enterprises where quality data and advanced sales intelligence matter most.

Is Lusha or ZoomInfo better?

ZoomInfo far outpaces Lusha for professional B2B sales. It includes buyer intent data, org charts, and robust firmographic data. 

Lusha is better for individual reps who just need quick contact details from LinkedIn at $29–69/month. But its limited credits (50–150/month) mean it can’t fuel scaled outbound sales efforts.
