FullContact is one of the most recognized names in identity resolution and customer data enrichment. Many RevOps and marketing leaders shortlist it because it promises to unify fragmented profiles across channels.

But like with any single-source vendor, questions come up fast: Are coverage rates high enough? Do contract terms lock us in? Is compliance handled with enough transparency?

Teams compare FullContact against other providers because the stakes are high. Low match rates drain SDR morale, high bounce rates damage deliverability, and annual contracts make experimentation risky.

That’s why buyers look at FullContact competitors offering waterfall enrichment, usage-based pricing, API-first integrations, and GDPR/CCPA-ready data flows.

This guide breaks down 7 of the top alternatives, backed by real user feedback from G2 and Reddit, and framed around the criteria that matter most: data accuracy and coverage, pricing transparency, ease of integration, and compliance confidence.

Here's a quick TLDR of the top fullcontact alternatives

1. FullEnrich: Maximum Coverage Without the Lock-In

If your main frustration with FullContact is coverage gaps and contract rigidity, FullEnrich is the obvious contrast. Instead of relying on a single database, it waterfalls across 20+ premium providers until it finds a verified match.

The result? Teams report 85%+ match rates compared to the 60–70% you’ll typically see from single-source vendors.

Add in transparent pricing starting at $29/month and flexible credit rollover, and it’s built for mid-market SaaS and RevOps teams that need predictable accuracy without $15k+ annual commitments.

Who FullEnrich is best for

RevOps, sales, and marketing teams that want higher verified coverage, API-first workflows, and pricing they can scale up or down with usage.

Key Features

• Waterfall enrichment across 20+ providers

• Triple verification (emails, phones, catch-alls)

• Both work + personal emails when available

• CSV uploads and real-time API/webhooks

• Credit rollover for 3 months

• Unlimited users on all plans

FullEnrich Pricing

• Starter: $29/month — usage-based, no lock-in

• Pro: $55/month with higher credits

• Scale/Enterprise: from ~$500/month, depending on volume

Pros and Cons of FullEnrich

Why FullEnrich over FullContact

• Multi-source waterfall → higher coverage vs. single-database enrichment

• Transparent monthly pricing vs. opaque annual contracts

• Compliance-ready with visible QA and GDPR workflows

G2 Rating: 4.8/5 on G2 (116 reviews)

FullEnrich is often praised for its reliable contact accuracy and simple enrichment workflow.

Charles C., Senior Product Manager, shared: 

"My business curates lead lists for customers, and adding FullEnrich to our workflow increased the volume of verified emails we could provide by 30% in the first month." (Source)

Bottom Line

FullEnrich is the best choice if you’re tired of paying enterprise pricing for partial coverage. It delivers higher match rates, flexible usage, and GDPR-aligned enrichment at a fraction of FullContact’s cost.

2. Apollo.io: Sales Intelligence and Outreach in One

Apollo takes a different angle from FullContact. Instead of focusing purely on enrichment, it combines a large B2B contact database with built-in sequencing, dialer, and analytics.

For teams that want an all-in-one sales stack, Apollo can replace both a data vendor and parts of your outreach platform.

The trade-off: data accuracy isn’t always as strong as coverage-first vendors like FullEnrich, especially in niche or international markets.

Who Apollo.io is best for

Budget-conscious sales teams that want data + outreach in one tool and don’t mind occasional accuracy trade-offs for the sake of convenience.

Key Features

• 200M+ contacts, 35M+ companies

• Chrome extension for LinkedIn and company sites

• Built-in email sequencing, dialer, and analytics

• CRM integrations (HubSpot, Salesforce, Pipedrive)

• Credits-based system for exports and enrichment

Apollo.io Pricing

• Free plan available

• Basic: $49/month per seat (annual)

• Professional: ~$79–$99/month per seat

• Organization: ~$119–$149/month per seat
  👉 See Apollo pricing on G2

Pros and Cons of Apollo.io

Ease of Use

Apollo earns praise for its Chrome extension and tight CRM integrations, which make it quick to start building lists. But many reviewers also note the UI can feel busy, and new users sometimes struggle to navigate all the features without training.

Why Apollo.io over FullContact

• One platform instead of stitching together data + engagement tools

• Free entry plan makes it accessible for early-stage teams

• Chrome workflow speeds up list-building directly from LinkedIn

What users are saying about Apollo.io

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

Apollo is a solid FullContact alternative if you want a single tool for enrichment, prospecting, and outreach. It won’t always deliver the same accuracy as a waterfall provider, but the convenience, free plan, and breadth of features make it attractive.

3. Cognism: GDPR-Compliant Coverage for Europe

Cognism has carved out its position by leaning hard into GDPR compliance and direct-dial accuracy. If FullContact leaves you worried about coverage in Europe or unclear data lineage, Cognism offers a more transparent, compliance-first option.

Its proprietary Diamond Data® focuses on verified mobile numbers and phone outreach — a clear differentiator if your sales playbook relies on calling.

Who Cognism is best for

Revenue teams targeting European markets who need verified direct dials and peace of mind on GDPR/CCPA compliance.

Key Features

• Verified mobile and direct phone numbers (Diamond Data®)

• GDPR-compliant enrichment with audit trails

• Global database but strongest in EU/UK coverage

• Intent data and technographics layered onto contact profiles

• Integrations with Salesforce, HubSpot, Outreach, SalesLoft

Cognism Pricing

• Pricing is quote-based and typically starts at ~$15,000/year

• Contracts are annual; cost scales with seats and data volume
  👉 See Cognism on G2

Pros and Cons of Cognism

Ease of Use

Reviewers note Cognism’s UI is straightforward and easy to adopt, especially for SDR teams working in Salesforce or HubSpot. However, some point out that the annual contract model can make experimentation harder compared to lighter, usage-based tools.

Why Cognism over FullContact

• Compliance-first: clear GDPR processes, DPA coverage, and data lineage visibility

• Stronger EU coverage: verified phone data beats generic databases

• Direct dial accuracy: particularly valuable for teams that rely on calling to drive pipeline

What users are saying about Cognism

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 go-to FullContact alternative for companies selling in Europe. It comes at a premium price, but if compliance and direct dials are mission-critical, the investment pays for itself.

4. LinkedIn Sales Navigator: Social Selling and Relationship Mapping

Unlike enrichment platforms that aggregate data from multiple providers, LinkedIn Sales Navigator builds on the world’s largest professional social network.

For teams who rely heavily on social selling and account-based outreach, it offers unmatched visibility into job changes, shared connections, and buyer intent signals from LinkedIn activity.

What it doesn’t provide is verified emails or direct dials — so most teams pair it with another enrichment tool to complete the workflow.

Who LinkedIn Sales Navigator is best for

Sales teams focused on relationship-driven selling and account mapping, especially in industries where LinkedIn is the primary buyer network.

Key Features

• Advanced search and account targeting filters

• InMail credits for direct outreach

• Alerts on job changes and company news

• CRM integrations (Salesforce, HubSpot, Dynamics)

• TeamLink for warm introductions via shared connections

LinkedIn Sales Navigator Pricing

• Core: $99/month per seat

• Advanced: ~$149/month per seat

• Advanced Plus: Custom enterprise pricing
  👉 See LinkedIn Sales Navigator pricing

Pros and Cons of LinkedIn Sales Navigator

Ease of Use

Sales Navigator is easy to adopt for anyone familiar with LinkedIn. The search filters and alerts are intuitive, though the reliance on InMail can be limiting if your outreach mix requires verified emails or phone calls.

Why LinkedIn Sales Navigator over FullContact

• Direct access to real-time buyer intent signals from LinkedIn activity

• Strong for relationship-driven sales where warm introductions matter

• Complements enrichment tools rather than replacing them

What users are saying about 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

LinkedIn Sales Navigator is the go-to alternative for social selling. It won’t replace FullContact’s enrichment capabilities, but it shines when you need to map accounts, track decision-makers, and personalize outreach based on live professional signals.

5. Lusha: Prospecting Simplicity for Individual Reps

Lusha made its name as a lightweight, Chrome-first prospecting tool. Where FullContact focuses on identity resolution, Lusha focuses on helping individual SDRs pull phone numbers and emails directly from LinkedIn or company websites.

The appeal is its low entry price and ease of setup, but it comes with trade-offs: limited coverage and lower match rates compared to waterfall-style enrichment.

Who Lusha is best for

Individual reps or small teams doing LinkedIn-centric prospecting who want a cheap, fast way to grab emails and numbers.

Key Features

• Chrome extension for LinkedIn and company domains

• Access to company and contact databases

• Basic CRM integrations (HubSpot, Salesforce)

• Pay-as-you-go credits system

• GDPR-compliant operations (EU focus)

Lusha Pricing

• Free plan available (limited credits)

• Pro: $29/month per seat

• Premium: ~$79/month per seat

• Scale/Enterprise: custom pricing
  👉 See Lusha pricing on G2

Pros and Cons of Lusha

Ease of Use

Ease of use is where Lusha shines. Install the Chrome extension, and reps can instantly pull data from LinkedIn profiles. However, the simplicity comes at a cost — teams scaling beyond individual prospecting will hit coverage and feature limitations quickly.

Why Lusha over FullContact

• Cheaper entry point with transparent seat pricing

• Faster for LinkedIn-first prospecting workflows

• Easier adoption for small sales teams or solo reps

What users are saying about Lusha

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

Lusha is the low-friction, budget-friendly option for reps who want fast access to contact details inside LinkedIn. For larger teams that need accuracy, coverage, or API workflows, tools like FullEnrich or Cognism will be a better fit.

6. Seamless.AI: High-Volume Prospecting at Speed

Seamless.AI pitches itself as the tool for fast, high-volume list building. Unlike FullContact’s identity-resolution focus, Seamless is all about enabling SDRs to spin up large lead lists directly from LinkedIn and company sites.

It’s attractive for teams that value speed and volume over precision — but accuracy can be hit-or-miss compared to enrichment-first vendors.

Who Seamless.AI is best for

SDR teams that prioritize volume and speed over bespoke data quality, and managers who want reps harvesting leads directly from their Chrome workflow.

Key Features

• Chrome extension for LinkedIn and company websites

• Real-time email and phone enrichment

• CSV import/export for bulk prospecting

• Integrations with Salesforce, HubSpot, Outreach

• AI-driven recommendations for lead targeting

Seamless.AI Pricing

• Free plan available

• Paid tiers: custom pricing based on seats and credits
  👉 See Seamless.AI reviews on G2

Pros and Cons of Seamless.AI

Ease of Use

Seamless is designed for speed. The Chrome extension makes it easy for reps to add leads on the fly. The downside: teams often find themselves managing credit limits and double-checking accuracy manually, which can slow down workflows at scale.

Why Seamless.AI over FullContact

• Ideal if you need high-volume list building quickly

• Chrome-first approach fits SDR daily workflow better

• Free tier lowers the barrier to initial testing

What users are saying about Seamless.AI

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

Seamless.AI is a good alternative to FullContact if your sales motion values quantity over precision. It’s perfect for SDRs building lists on LinkedIn, but teams focused on accuracy and compliance will find more reliable options elsewhere.

8. Lead411: Verified Emails with Intent Data

Lead411 takes a more verification-first approach compared to FullContact. It combines a large B2B contact database with triple-verified emails and overlays intent data to help teams target prospects more intelligently.

For companies frustrated with bounced emails or stale data, Lead411 positions itself as a deliverability-focused alternative with solid coverage in North America.

Who Lead411 is best for

Sales and marketing teams that want high email accuracy plus intent data to prioritize outreach.

Key Features

• Triple-verified emails with ~96% deliverability

• Direct dials and mobile numbers where available

• Bombora-powered intent data to surface in-market accounts

• CRM integrations (HubSpot, Salesforce, Outreach, SalesLoft)

• List building with advanced filters (industry, technographics, funding)

Lead411 Pricing

• Basic plan: $75/month per user

• Pro and Enterprise tiers scale with users and credits
  👉 See Lead411 on G2

Pros and Cons of Lead411

Ease of Use

Lead411’s platform is straightforward — reviewers say it’s easy to build lists and export data, though the interface feels less modern compared to Apollo or Clearbit. Setup is quick, and CRM integrations are solid.

Why Lead411 over FullContact

• Better deliverability: verified emails with intent context reduce wasted sequences

• North America focus makes it strong for U.S.-centric go-to-market teams

• Affordable monthly pricing is easier for mid-market buyers to justify

What users are saying about Lead411

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 FullContact alternative if your priority is email deliverability and intent signals. It may not have the slick UI or EU coverage of other tools, but for U.S.-focused sales teams it delivers solid value.

Why FullEnrich Stands Out as the Best FullContact Alternative

FullContact is widely known in the identity resolution space, but its single-source model leaves many RevOps and sales teams frustrated with coverage gaps and opaque contracts. This is where FullEnrich has a decisive edge.

1. Higher Coverage Through Waterfall Enrichment

Instead of relying on one database, FullEnrich waterfalls across 20+ premium providers until it finds a verified match.

The result: customers consistently see 85%+ match rates, compared to the 60–70% range common with single-source vendors. That difference means more valid contacts, fewer wasted sequences, and happier SDR teams.

2. Transparent, Flexible Pricing

FullEnrich starts at $29/month — a clear contrast to FullContact’s quote-only, annual-contract model. Credits roll over for three months, so you’re not punished for uneven usage.

For mid-market B2B SaaS companies, this makes budgeting predictable and scalable without six-figure commitments.

3. Compliance and Trust Built-In

Data lineage and GDPR/CCPA compliance aren’t afterthoughts. FullEnrich provides visible QA metrics, audit-ready processes, and clear DPAs, giving RevOps leaders confidence that enrichment won’t create legal or reputational risk.

4. Developer- and RevOps-Friendly Integrations

With real-time APIs, CSV bulk enrichment, and webhook support, FullEnrich plugs into modern RevOps stacks — HubSpot, Salesforce, Snowflake, and beyond. Technical teams can customize enrichment flows instead of being locked into rigid CSV uploads.

If your main concerns with FullContact are coverage, contract lock-in, or compliance clarity, FullEnrich is the strongest alternative. It’s built for mid-market SaaS and RevOps teams who need verified, high-coverage enrichment at a transparent, usage-based price point.
