People Data Labs built its name on offering a large database of company data and identity resolution through API access.

But teams that depend on accurate contact data often run into trade-offs: limited verification, uneven data freshness, and contracts that don’t always scale with usage.

The good news is that People Data Labs isn’t your only option.

In 2025, there are multiple data enrichment platforms and sales intelligence tools that provide broader data points, more transparent pricing plans, and stronger GDPR/CCPA compliant data practices.

In this guide, I’ll compare 12 proven People Data Labs alternatives. The evaluation is based on:

• Data accuracy and coverage: How reliable and up to date are the contact and company data sets?

• Pricing structure: Do plans scale with usage, or lock you into annual contracts?

• Ease of use: Can RevOps teams set it up quickly without burning engineering hours?

• Credit flexibility: Are unused credits lost, or do they roll over?

• Integration options: How well do they connect to CRMs, warehouses, and engagement tools?

• Compliance: Is the provider GDPR compliant and transparent about data lineage?

Quick Rundown: Top People Data Labs Alternatives in 2025 👇

1. FullEnrich: Waterfall Enrichment for Higher Match Rates

Most enrichment vendors, including People Data Labs, depend on a single large database. The trade-off is obvious: when the source doesn’t have the record, you’re left with gaps.

FullEnrich takes a different path. It runs every request through 20+ premium providers in sequence until it finds a verified match. This “waterfall” approach consistently delivers 85%+ match rates and cuts down the bounce risk that frustrates SDR teams.

Who FullEnrich is Best For

• RevOps and SalesOps leaders who need verifiable coverage without paying $10k+ for legacy contracts.

• Mid-market B2B SaaS companies that rely on accurate contact data to keep outbound campaigns and PLG activation on track.

Key Features

• Waterfall enrichment across 20+ sources for maximum coverage.

• Triple verification on emails, including catch-all detection.

• Access to both professional and personal emails, plus direct dials and mobile numbers.

• API-first design with bulk CSV uploads and easy CRM integrations (HubSpot, Salesforce).

• Credit rollover for up to 3 months.

• Unlimited seats included in every plan.

Ease of Use

FullEnrich was built with RevOps in mind. Most teams can connect their CRM in under 30 minutes, and bulk CSV enrichment is straightforward. The API is developer-friendly, with clear docs and webhook support for automation. Compared to heavier sales intelligence platforms, the setup curve is minimal.

FullEnrich Pricing

• Free trial: 50 credits

• Starter – $29/mo (500 credits)

• Pro – $55/mo (1,000 credits)

• Scale – custom from $500/mo (volume + SSO)

• One-time – $299 (5,000 credits, valid 6 months)

• Credits rollover for 3 months so it reduces waste across paid plans as teams scale

Why FullEnrich Over People Data Labs

• Coverage: Waterfall enrichment vs. single-source lookups means fewer gaps.

• Verification: Triple-checked emails keep bounce rates low and protect domain health.

• Pricing structure: Simple, usage-based tiers with rollover, no opaque enterprise contracts.

What Users Are Saying

On G2, FullEnrich holds a strong 4.8/5 rating, and the same themes keep coming up: accuracy, coverage, and how easy it is to use.

Vianney V., Head of Growth at a small business, put it this way:

“What I like best about FullEnrich is its ability to provide exceptional data quality with a bounce rate of around 1%, the lowest in the industry. This is made possible through its three different email verification services, ensuring high accuracy in the collected information...” (Read full review here)

Another reviewer in the software space kept it simple:

“I appreciate how easy FullEnrich is to use, even for new team members... The tool offers a high success rate in finding emails and phone numbers, making it reliable for contact discovery... I had to reach out to support only once, and their response time was impressively fast." (Read full review here)

The pattern is clear: low bounce rates, reliable contact data, and a user-friendly interface that new reps pick up quickly. For SDR teams, that means less wasted effort and more confidence in the data

Bottom Line

If you’re looking for a best alternative to People Data Labs, FullEnrich stands out for its data accuracy, compliance, and transparent pricing. It’s a practical fit for mid-market SaaS teams that need reliable enrichment without locking into legacy vendor contracts.

2. Clearbit (Now Breeze): Real-Time Enrichment Inside HubSpot

Clearbit is often mentioned alongside People Data Labs, but it serves a different purpose. Rather than being a standalone sales intelligence platform, Clearbit is now tightly integrated into HubSpot.

Its core value lies in real-time enrichment of form fills and website visitor tracking through Reveal. If you’re outside the HubSpot ecosystem, Clearbit won’t function as a broad enrichment tool.

Who Clearbit is Best For

• Marketing Ops teams running HubSpot who want to shorten forms and enrich leads automatically.

Key Features

• Form enrichment inside HubSpot — pull firmographic and technographic data instantly.

• Reveal for website visitor tracking — de-anonymize traffic and tie visits to company accounts.

• Segmentation and targeting support for HubSpot-based ABM programs.

• Continuous real-time updates to HubSpot records.

Ease of Use

Because it’s native to HubSpot, setup is straightforward. Teams can activate enrichment and visitor tracking without engineering support. For non-HubSpot CRMs like Salesforce, though, Clearbit is no longer an option.

Clearbit Pricing

• Clearbit is sold as a HubSpot add-on with custom pricing.

• The standalone Clearbit free plan was discontinued in 2025.

• Public starting prices are not listed.

Pros and Cons

Why Clearbit Over People Data Labs

• HubSpot-native: If your stack is HubSpot, Clearbit is easier to deploy than building an API workflow with PDL.

• Inbound focus: Helps capture more from website traffic and form fills.

• Speed: Enrichment happens instantly inside HubSpot workflows.

What Users Are Saying

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

Clearbit is best if your company runs entirely on HubSpot and you need real-time enrichment and visitor tracking for inbound leads. It is not a standalone sales intelligence tool and does not work for Salesforce or other CRMs.

3. ZoomInfo: Enterprise-Grade Sales Intelligence

ZoomInfo is a full-scale sales intelligence platform with millions of company and contact records, layered with buyer intent data and sales engagement tools.

It’s often the default choice for enterprise sales teams, though mid-market SaaS companies sometimes find the trade-offs in cost and contract flexibility hard to justify.

Who ZoomInfo is Best For

• RevOps leaders running account-based marketing with intent signals and firmographic data.

Key Features

• Large B2B database with firmographic, technographic, and demographic data.

• Buyer intent data sourced from web activity and partner networks.

• Built-in sales engagement tools: dialers, sequences, and territory planning.

• Website visitor tracking via ZoomInfo WebSights.

• Native CRM integrations with Salesforce, HubSpot, and others.

Ease of Use

ZoomInfo is feature-rich but also heavy. Teams often face a steeper learning curve and need training to get full value. Compared to People Data Labs’ API-first workflow, ZoomInfo offers more of a turnkey solution, but it can overwhelm smaller teams with its scope.

ZoomInfo Pricing

• No public pricing; all plans are custom.

• Contracts are typically annual and run into the five-figure range.

• Credits are required for most actions, with little flexibility for rollover.

Pros and Cons

Why ZoomInfo Over People Data Labs

• Platform scope: ZoomInfo includes not just data, but engagement and intent tools.

• Enterprise standard: Recognized by many CROs as the default vendor in sales intelligence.

• Ecosystem: Deeper integrations with sales engagement platforms compared to PDL’s enrichment API.

What Users Are Saying

ZoomInfo SalesOS holds a 4.5/5 rating on G2, but users report both strengths and weaknesses.

Some highlight the value of its massive database and integrations. Laura K. (Mid-Market) wrote:

“The database is huge, and there are a lot of filters that allow you to slice your search into endless configurations… The integration and API with Salesforce works well.” (Source)

Others raise concerns about cost and product complexity. Will O., CEO (Mid-Market), shared:

“I liked the idea of ZoomInfo, but they do not deliver on it… they rotate their sales people frequently so I have never had a consistent person to help me improve my usage… I believe it is the most expensive option out there.” (Source)

Bottom Line

ZoomInfo is a strong People Data Labs alternative if you’re an enterprise team that needs all-in-one sales intelligence with intent data, visitor tracking, and engagement tools. For mid-market SaaS, the pricing and credit rules often make leaner tools like FullEnrich more practical.

4. Apollo.io: Budget-Friendly All-in-One Platform

Unlike People Data Labs, which is API-first and dataset-focused, Apollo.io combines data enrichment with a full sales engagement platform.

It’s widely adopted by startups and mid-market SaaS teams because it packages prospecting, sequencing, and email outreach in one affordable tool.

Who Apollo.io is Best For

• SDR teams that want prospecting, enrichment, and sequencing in one interface.

Key Features

• Access to a large database of companies and contacts.

• Built-in sales engagement tools: sequencing, dialer, email automation.

• Basic data enrichment with firmographic and technographic details.

• Chrome extension for LinkedIn prospecting.

• Integrations with Salesforce, HubSpot, Outreach, and other tools.

Ease of Use

Apollo.io is straightforward for SDRs and AEs, with workflows that resemble sales engagement platforms more than data enrichment APIs. It’s easy to start prospecting quickly, but larger RevOps teams may find the enrichment depth lighter compared to specialized providers.

Apollo.io Pricing

• Free plan available

• Basic $59/user/mo (annual $49)

• Professional $99/user/mo (annual $79)

• Organization $149/user/mo (annual $119)

• No credit rollover – unused credits vanish, especially noticeable at scale per user.

Pros and Cons

Why Apollo.io Over People Data Labs

• All-in-one workflow: PDL enriches data, but Apollo.io lets you prospect and engage directly.

• Budget-friendly: A fraction of the cost of enterprise data vendors.

• Speed: SDRs can start building and emailing lists without engineering resources.

What Users Are Saying

Apollo.io holds a 4.7/5 rating on G2, but reviews show mixed experiences.

Some users highlight the all-in-one value. As Saqib I., RCM Executive at a small business, put it:

“Apollo combines prospecting, engagement, and CRM-like features in one platform… The email sequencing and automation tools help streamline outreach and improve response rates.” (Source)

Other users warn about serious issues. Adam W., a Founder at a small business, wrote:

“...run for the hills, seriously the data is bad, the billing is worse, and the customer no service even worse!… they will then keep taking money over and over and refuse to refund even when you cancel.” (Source)

Bottom Line

Apollo.io is a practical People Data Labs alternative if you need a budget-friendly, all-in-one sales platform. For teams that prioritize accuracy, compliance, or advanced enrichment pipelines, tools like FullEnrich or Cognism will be stronger fits.

5. Cognism: GDPR-Compliant European Coverage

Where People Data Labs focuses on raw datasets and Apollo.io emphasizes affordability, Cognism differentiates through GDPR-compliant contact data and a strong foothold in Europe.

It’s particularly valued by companies that need accurate direct dials and mobile numbers in regions where compliance and verification standards are strict.

Who Cognism is Best For

• RevOps leaders who need GDPR/CCPA-compliant data without legal grey areas.

Key Features

• Verified direct dials and mobile numbers with human verification.

• GDPR-compliant database designed for UK and EU regulations.

• Chrome extension for LinkedIn prospecting and enrichment.

• Intent data and technographic filters to narrow target lists.

• Integrations with Salesforce, HubSpot, Outreach, and SalesLoft.

Ease of Use

Cognism is positioned more like ZoomInfo than People Data Labs: a full sales intelligence platform with a UI. Teams note that onboarding is straightforward, and the Chrome extension makes day-to-day prospecting simple. The bigger lift comes in aligning enterprise-level contracts and workflows.

Cognism Pricing

• Platform: ~$15,000/year

• Enterprise: $25,000+ annually

• Most plans include unlimited exports and Diamond Data®

Pros and Cons

Why Cognism Over People Data Labs

• Compliance: Fully GDPR/CCPA compliant, removing the risk of questionable data sourcing.

• Verification: Human-verified mobile numbers for better outreach performance.

• Regional focus: Superior coverage in Europe compared to People Data Labs’ US-centric data.

What Users Are Saying

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

Cognism is the right People Data Labs alternative if your pipeline depends on verified, GDPR-compliant contact data in Europe. For US-centric teams or those on tighter budgets, Apollo.io or FullEnrich may be a better fit.

6. Lusha: Chrome Extension for Fast Prospecting

Lusha takes a very different approach than People Data Labs. Instead of focusing on APIs or massive databases, it’s designed for individual prospecting at speed.

With its Chrome extension, reps can quickly pull phone numbers and email addresses directly from LinkedIn or company websites. It’s popular with SDRs who need instant access to contact data but less suited for large-scale enrichment workflows.

Who Lusha is Best For

• SDRs and AEs doing LinkedIn-based prospecting.

Key Features

• Chrome extension for quick access to phone numbers and emails.

• Basic company data including firmographics.

• API for limited integration into CRM or sales engagement tools.

• Credit-based system for contact lookups.

• Browser-based prospecting workflow.

Ease of Use

Lusha is known for its simplicity. The extension works directly in LinkedIn and websites, meaning reps can start pulling contacts instantly. Compared to People Data Labs’ API-first model, Lusha requires no engineering but offers far less flexibility for RevOps teams.

Lusha Pricing

• Free plan available

• Pro ~$49/user/month

• Premium ~$79/user/month

• Scale – custom contracts

• Monthly rollover included; annual plans reset credits at year end, so choose paid plans carefully.

Pros and Cons

Why Lusha Over People Data Labs

• Speed: Instant access to contacts via browser extension vs. API workflows.

• Simplicity: No setup required; reps can self-serve.

• Affordability: Lower entry cost than large-scale enrichment vendors.

What Users Are Saying

Lusha holds a 4.3/5 rating on G2, with reviews showing both positives and drawbacks.

Some users highlight ease of use and time savings. Murtaza P., Demand Generation Manager (Small Business), wrote:

“Lusha makes it easy for me to find accurate contact details of important decision-makers… The tool is very user-friendly and saves a lot of time for my team.” (Source)

Others raise serious concerns about accuracy and transparency. Trisha G., President and CEO (Small Business), shared:

“... either they are 40% inaccurate or we are one unlucky customer… I wouldn't recommend anyone to this platform… Lusha tricks customers in by their false claims.” (Source)

So, Lusha is quick, affordable, and simple for small teams, but if accuracy and reliability are top priorities, it may not be the best choice.

Bottom Line

Lusha is a good People Data Labs alternative if you need fast, lightweight prospecting from LinkedIn. For larger teams, deeper accuracy, or GDPR-compliant enrichment, tools like FullEnrich or Cognism are stronger fits.

7. Seamless.AI: Chrome-First High-Volume Prospecting

Seamless.AI is built for reps who want to generate lists quickly, not for RevOps teams building enrichment pipelines. Unlike People Data Labs, which is API-driven, Seamless.AI runs as a Chrome extension that lets SDRs pull contacts while browsing LinkedIn or company sites.

It’s a speed play: less focus on compliance or verification, more on fueling outbound volume.

Who Seamless.AI is Best For

• SDR teams that value volume and speed over enrichment precision.

Key Features

• Chrome extension to pull contacts from LinkedIn or company websites.

• Bulk list building with email and phone enrichment.

• CSV import/export for quick uploads to CRMs.

• Integrations with Salesforce, HubSpot, and other sales engagement tools.

• Credit-based pricing tied to usage.

Ease of Use

Seamless.AI is straightforward for reps: install the extension, pull data, and export. Compared to People Data Labs’ API, it requires no setup but gives RevOps less control. Accuracy can vary, and manual verification may still be needed.

Seamless.AI Pricing

• Free plan available with limited credits.

• Paid tiers are custom; pricing and credit rules vary.

• Teams usually negotiate based on expected volume.

Pros and Cons

Why Seamless.AI Over People Data Labs

• Speed: Faster list building compared to API workflows.

• Accessibility: Easy for SDRs to use without technical setup.

• Volume: Good for teams prioritizing large outbound list generation.

What Users Are Saying

Seamless.AI has a 4.4/5 rating on G2.

Some users value its speed and integrations. Ayan M., ServiceNow Consultant (Small Business), said:

“I really like how Seamless.AI helps me quickly find contact info for the people I want to reach out to… The Chrome extension makes it simple to use while browsing, and it works well with tools like Salesforce.” (Source)

Others point to accuracy and contract issues. A Verified User in Motion Pictures (Small Business) wrote:

“Seamless.ai failed us on two fronts: product and posture… results were underwhelming and the vaunted ‘intent’ search was practically unusable…” (Source)

Bottom Line

Seamless.AI is a People Data Labs alternative if your main priority is fast, high-volume US prospecting. If you need verified accuracy, GDPR compliance, or structured enrichment pipelines, FullEnrich or Cognism are better options.

8. Lead411: Triple-Verified Data with Intent Signals

Lead411 positions itself as a balance between data accuracy and affordability. Unlike People Data Labs’ dataset-driven model, Lead411 emphasizes triple-verified contact data and layers in intent signals to help teams prioritize outreach.

It’s particularly useful for sales teams that need reliable emails and phone numbers without paying enterprise-level prices.

Who Lead411 is Best For

• RevOps leaders who want intent data to prioritize accounts.

Key Features

• Triple-verified emails with intent scoring.

• Direct dials and mobile numbers with accuracy checks.

• Company firmographics and technographics.

• Integrations with Salesforce, HubSpot, Outreach, and SalesLoft.

• Intent data powered by Bombora.

Ease of Use

Lead411 is simpler to use than enterprise platforms. Teams can build lists with filters and push them directly to CRMs. The UI is straightforward, though less sophisticated than ZoomInfo’s or Apollo’s engagement features.

Lead411 Pricing

• Basic plans start around $75 per month.

• Higher tiers add more credits, advanced filters, and integrations.

• Pricing is credit-based, with different tiers for individual users and teams.

Pros and Cons

Why Lead411 Over People Data Labs

• Verification: Triple-checking emails for stronger accuracy than PDL’s raw data.

• Intent data: Helps prioritize accounts, not just enrich them.

• Affordability: Mid-market friendly pricing compared to enterprise alternatives.

What Users Are Saying

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

Lead411 is a practical People Data Labs alternative if you need verified, intent-enriched contact data at a manageable price point. For broader EU coverage, Cognism may be stronger, while FullEnrich wins on credit flexibility and waterfall match rates.

Why FullEnrich is the Best People Data Labs Alternative

Not all enrichment tools solve the same problems. People Data Labs gives you a dataset and API, but it leaves gaps in accuracy, pricing transparency, and compliance. FullEnrich was built to address those gaps directly, making it the most practical alternative for mid-market SaaS teams.

1. Accuracy and Coverage

FullEnrich uses a waterfall enrichment model across 20+ premium providers, reaching 85%+ match rates on contact and company data. Instead of depending on a single database like People Data Labs, it keeps running until a verified match is found. This means fewer gaps in your CRM and a healthier sales pipeline.

2. Transparent Pricing

Where People Data Labs can feel opaque with usage-based pricing and enterprise contracts, FullEnrich offers simple monthly tiers starting at $29. Credits roll over for up to three months, and all plans include unlimited seats. No hidden fees, no surprise renewals.

3. Verified Data

FullEnrich applies triple verification on email addresses, including catch-all detection. It also provides both work and personal emails, plus mobile numbers, to reduce bounce rates and increase connect rates.

4. Integrations and Ease of Use

RevOps teams can connect FullEnrich to HubSpot, Salesforce, and major warehouses in under 30 minutes. The API is developer-friendly, with webhook support and bulk CSV options. Compared to People Data Labs’ raw dataset approach, this means faster time-to-value and less engineering lift.

5. Compliance and Trust

FullEnrich is fully GDPR and CCPA compliant, with clear data lineage and auditability. For teams in Europe or with strict data policies, this provides peace of mind that People Data Labs doesn’t always deliver.

FullEnrich isn’t just an alternative to People Data Labs — it’s a more accurate, transparent, and compliant solution for modern RevOps. FullEnrich gives you the flexibility to scale without overpaying.
