Best Data Enrichment Platforms (2026)

Poor data quality costs the average organization $12.9 million per year, according to Gartner. For B2B sales teams, the damage is more specific: bounced emails, wasted prospecting hours, and pipelines clogged with contacts who changed jobs six months ago.

B2B contact data decays at roughly 2.1% per month -- about 22-25% annually. Enrich your database in January, and nearly a quarter is stale by December. A 2025 IBM study found that over 25% of organizations estimate they lose more than $5 million annually from poor data quality alone, with 7% reporting losses above $25 million.

Data enrichment platforms solve this by appending missing firmographic, technographic, and contact data to your CRM records, verifying what you have, and flagging when information goes stale. The market is now worth an estimated $2.9 billion and growing at 10-12% CAGR through 2030.

But these platforms range from $29/month startups to six-figure enterprise contracts, and they vary wildly in accuracy, coverage, and what data they actually provide. This guide breaks down the 10 platforms worth evaluating in 2026, with verified pricing, honest trade-offs, and a framework to match the right tool to your team.

How to Evaluate a Data Enrichment Platform

Before comparing specific tools, establish what actually matters for your use case. These five criteria separate useful platforms from expensive address books.

1. Data Accuracy and Verification Method

The single most important factor. A platform claiming 300 million contacts is meaningless if 30% of those emails bounce. Ask how data is verified: AI-predicted, community-contributed, or human-verified? Cognism reports that phone-verified mobile numbers produce an 87% connect rate vs. 30% for unverified industry averages -- a nearly 3x improvement from the same list. This gap alone can justify a premium price.

2. Coverage Depth vs. Breadth

Some platforms excel at email addresses but lack technographic or intent data. Others provide deep firmographic profiles but weak phone number coverage. Map your enrichment needs: direct dials for cold calling? Technographics for personalized outreach? Behavioral signals to prioritize accounts? The best platform depends on what data you actually use in your workflow.

3. Pricing Model Transparency

Credit-based, seat-based, unlimited access, or hybrid -- every vendor structures pricing differently. The sticker price rarely tells the full story. Watch for: credit expiration policies, per-user add-on costs, overage charges, and annual renewal increases. A platform that looks cheap at 5,000 credits/month gets expensive fast when your SDR team burns through those in week two.

4. CRM and Workflow Integration

Enrichment data that lives in a separate tab is data that nobody uses. Look for native integrations with your CRM (Salesforce, HubSpot), your sales engagement platform (Salesloft, Outreach), and any data orchestration tools (Clay, Census) you already run. API quality matters too -- evaluate rate limits, response times, and field coverage if you plan to enrich programmatically.

5. Compliance and Data Sourcing

With GDPR enforcement increasing and CCPA expanding, how a vendor sources its data matters more than ever. Platforms that rely heavily on web scraping face ongoing legal risk. Those with explicit opt-in data, licensed partnerships, or human verification tend to carry lower compliance exposure.

The 10 Best B2B Data Enrichment Platforms (2026)

1. ZoomInfo -- The Enterprise Standard

ZoomInfo dominates the enterprise sales intelligence market with over 321 million professional profiles and a reported $250 million annual investment in data. It is the default choice at companies with 500+ employees and dedicated RevOps teams.

• Pricing: Starts at $14,995/year (Professional, 5,000 credits, 3 users). Advanced plan at $24,995/year adds intent data and 10,000 credits. Elite tier runs $35,000-$45,000+. Additional seats run ~$1,500-$2,500 each depending on tier. Real-world contracts for mid-market teams typically land at $25,000-$60,000/year. Annual contracts only, with 10-20% renewal increases standard.
• Best at: Enterprise account coverage, intent data (Bidstream + first-party), org chart mapping, and workflow automation. Strong technographic depth for data-driven account targeting.
• Watch out for: Credit overages can double your bill. Add-ons (intent data, API access, advanced features) cost $5,000-$20,000/year extra. Interface has a steep learning curve. Smaller companies find the minimum spend hard to justify.
• Best fit: Mid-market and enterprise teams with $25K+ annual budgets who need depth across firmographic, technographic, and intent data.

2. Apollo.io -- Best Value for Outbound Teams

Apollo.io has become the default prospecting tool for startups and mid-market sales teams, combining a 270M+ contact database with built-in email sequencing, dialer, and LinkedIn automation. It is the rare platform where you can find contacts, enrich them, and run cold email sequences from one tool.

• Pricing: Free tier (100 credits/month). Paid plans at $49/user/month (Basic, 5,000 credits), $79/user/month (Professional, 10,000 credits), $119/user/month (Organization, 15,000 credits) -- billed annually. Monthly billing runs 20% higher. Additional credits at $0.20 each. All credits expire at billing cycle end.
• Best at: Mid-market contact coverage, all-in-one prospecting workflow, and price-to-volume ratio. Most users report 70-80% email find rates. Strong for teams running AI-powered outbound at scale.
• Watch out for: Phone number accuracy lags behind Cognism. European and APAC data quality is weaker than North American coverage. Heavy usage can burn through credits fast -- a single user running 50 lookups/day hits 1,000 credits in a month.
• Best fit: Outbound-heavy SDR teams at startups and mid-market companies who want prospecting + enrichment + sequencing in one platform for under $100/user/month.

3. Cognism -- Best for European Data and Phone Numbers

Cognism differentiates on two fronts: GDPR-compliant European data coverage and Diamond Data -- manually phone-verified mobile numbers with a claimed 98% accuracy rate and over 10 million verified contacts globally. If your team does significant cold calling or sells into EMEA, Cognism is the specialist.

• Pricing: Platinum tier starts at approximately $1,500-$10,000/year. Diamond tier (with phone-verified mobiles) runs $2,550-$25,000/year. Diamond plan access fee is approximately $25,000 + $2,500/user. License-based, not credit-based, so you get unlimited views and exports within your tier. Pricing is not publicly listed -- you must speak with sales.
• Best at: European/EMEA data accuracy, phone-verified mobile numbers (87% connect rate vs. 30% industry average), GDPR compliance, and intent data via Bombora partnership. 95% of VP+ contacts refreshed every 60 days.
• Watch out for: North American coverage is thinner than ZoomInfo or Apollo. Less useful if you do not do outbound calling. Pricing opacity means you cannot comparison-shop without committing to a demo.
• Best fit: Teams selling into European markets or running heavy outbound calling motions who need verified direct dials.

4. Lusha -- Best for Quick Lookups and Small Teams

Lusha focuses on simplicity: find email addresses and phone numbers fast, primarily through a Chrome extension that overlays on LinkedIn profiles. It is the lightest-weight tool on this list and the easiest to adopt.

• Pricing: Free plan (40 credits/month). Pro at $22.45/user/month (3,000 annual credits). Premium at $52.45/user/month (7,200 annual credits). Scale plan with custom pricing adds intent signals, job change alerts, CRM enrichment, and API access. Emails cost 1 credit; phone numbers cost 5 credits. Monthly billing available at higher rates (up to $79.90/user/month).
• Best at: Speed of adoption (Chrome extension installs in 30 seconds), affordable per-user pricing, and straightforward UX. Good for individual reps who need contact info immediately.
• Watch out for: Limited firmographic and technographic enrichment. Intent signals, technographic filters, and CRM integration locked behind the Scale tier. CSV enrichment only on Premium+ plans. Credit-to-phone-number ratio means phone lookups drain credits 5x faster.
• Best fit: Individual reps, small sales teams (under 10), and orgs that primarily need email addresses and occasional phone numbers without deep analytics.

5. Clay -- Best for Orchestrated Waterfall Enrichment

Clay is not a traditional data provider -- it is a data orchestration layer that connects to 150+ enrichment providers and runs waterfall enrichment sequences across them. If one provider cannot find an email, Clay automatically queries the next. Industry benchmarks show this approach pushes match rates from 30-60% (single provider) to 80%+ (waterfall).

• Pricing: Starter at $149/month (2,000 credits/month, $134/month annual). Explorer at $349/month (10,000 credits). Pro at $800/month (50,000 credits). Enterprise custom. All plans include unlimited team members. Credit costs drop from ~$0.075/credit (Starter) to ~$0.016/credit (Pro) at scale. Unused credits roll over up to 2x monthly allocation.
• Best at: Maximizing enrichment coverage by combining multiple providers, building complex enrichment workflows with AI, and teams that already use multiple data tools and want to unify them. Pairs well with HubSpot and Salesforce for CRM-synced workflows.
• Watch out for: Credit costs can be unpredictable -- a single waterfall across 5 providers might use 15-30 credits per record. Requires understanding of workflow design (there is a real learning curve). Does not include its own proprietary database.
• Best fit: RevOps teams and growth engineers who want maximum coverage and are comfortable building enrichment workflows. Not for teams that want plug-and-play.

6. Clearbit (Breeze Intelligence by HubSpot) -- Best for HubSpot-Native Teams

HubSpot acquired Clearbit in December 2023 and rebranded it as Breeze Intelligence, embedding its enrichment capabilities natively into HubSpot's CRM. If your team already runs on HubSpot, this is the most seamless enrichment option available.

• Pricing: Starts at $45/month for 100 credits (annual billing, plus requires a paid HubSpot subscription at $30+/month minimum). 1 enrichment = 10 HubSpot Credits, with credits priced at $10 per 1,000. No credit rollover -- monthly resets. Real-world costs range from $12,000-$80,000/year depending on volume. All free Clearbit access (including legacy Reveal Lite) was officially sunset in 2025.
• Best at: Real-time visitor identification (de-anonymize website traffic), automatic CRM enrichment within HubSpot, form shortening (reduce form fields by enriching on submission), and strong SaaS company coverage.
• Watch out for: Only works within the HubSpot ecosystem -- no standalone access. Credit costs compound quickly at scale. Monthly resets with no rollover punish uneven usage. Some G2 reviews report narrower coverage since the acquisition.
• Best fit: Marketing and sales teams fully committed to HubSpot who want enrichment baked into their existing CRM without adding another vendor.

7. Seamless.AI -- AI-Powered Real-Time Search

Seamless.AI uses artificial intelligence to search the web in real-time and compile contact information, rather than relying on a static database. This gives it the ability to surface fresher data than some competitors, though at the cost of occasional inconsistency.

• Pricing: Free plan (50 lifetime credits). Basic at ~$147/month (billed annually). Pro pricing varies by team size -- reports range from $79-$299/user/month, with a minimum of 5 users on Pro ($9,000+/year minimum). Enterprise plans range from $20,000-$100,000+/year. Annual contracts only. Seamless.AI does not publicly list pricing -- you must contact sales.
• Best at: Real-time data discovery (not limited to a fixed database), Chrome extension for LinkedIn prospecting, and teams willing to verify results independently.
• Watch out for: Data enrichment, intent signals, job change alerts, and the AI assistant are all paid add-ons. Contract lock-in with annual-only billing. G2 reviews frequently mention aggressive upselling and difficult cancellation. Accuracy is inconsistent compared to database-first providers.
• Best fit: Teams that want AI-powered prospecting and are willing to layer in email verification. Pair with NeverBounce or ZeroBounce for validation.

8. SalesIntel -- Best for Human-Verified Accuracy

SalesIntel takes a different approach to data quality: it employs a team of human researchers who verify contact data every 90 days. The result is a claimed 95% accuracy rate and a unique Research-on-Demand service where you can request specific contacts that are not in the database.

• Pricing: Individual plans from $99/month. Team plans start around $5,000/year and scale based on user licenses. Enterprise packages with Research-on-Demand, intent data, and advanced features can reach $18,000-$48,000+/year. SalesIntel has moved toward unlimited data access within plans (not credit-based), which simplifies budgeting.
• Best at: Data accuracy through human verification, Research-on-Demand for hard-to-find contacts (submit requests for specific people/companies), and firmographic + technographic + intent data (via Bombora partnership). Unlimited enrichment within plans means predictable costs.
• Watch out for: Smaller database than ZoomInfo or Apollo. Human verification introduces slight delays on Research-on-Demand. Higher minimum price than lighter tools. Less useful for high-volume, low-touch prospecting.
• Best fit: Mid-market teams that prioritize accuracy over volume and sell into niche verticals where generic databases often have gaps.

9. 6sense -- Best for Account-Level Intent and ABM

6sense is not primarily a contact enrichment tool -- it is an ABM platform that identifies in-market accounts by analyzing over 500 billion intent signals. But its enrichment capabilities (contact discovery, firmographic append, technographic data) make it a compelling option for enterprise teams running account-based motions.

• Pricing: Free tier (50 credits/month). Enterprise plans start at $60,000-$130,000/year, with full implementation costs reaching $120,000-$150,000/year for large deployments. Display ad account targeting costs $5,000-$30,000/year depending on volume. Multi-year contracts are standard, and discounts are negotiable (especially at quarter-end).
• Best at: Identifying which accounts are actively researching your category before they fill out a form, orchestrating multi-channel ABM campaigns, and predictive analytics that score account readiness. Pairs with behavioral analytics for full-funnel visibility.
• Watch out for: Not a standalone enrichment tool -- you need the full ABM platform to get value. Implementation is complex and can take months. Pricing is opaque and enterprise-only. Overkill for teams doing traditional outbound prospecting.
• Best fit: Enterprise marketing and sales teams running mature ABM programs who need intent signals to prioritize accounts across the buying committee.

10. FullEnrich -- Best for Maximum Coverage at Low Cost

FullEnrich is a newer entrant focused exclusively on waterfall enrichment for email and phone data. It pulls from 15+ premium data providers and runs triple email validation to achieve sub-1% bounce rates. Think of it as a simpler, more affordable version of Clay's waterfall approach.

• Pricing: Free trial (50 credits). Paid plans start at $29/month. Monthly, annual, and one-time payment options available. Credits roll over for up to 3 months (monthly plans) or 12 months (annual). Enterprise custom pricing for high-volume teams. G2 ease-of-use score of 9.2/10.
• Best at: Pure contact enrichment (email + phone), maximizing find rates through multi-provider waterfall, triple email verification, and the simplest setup on this list. Users report 65-85% enrichment rates -- competitive with Clay at a fraction of the price.
• Watch out for: No firmographic, technographic, or intent data. No built-in outreach tools. Newer company with a smaller track record. Not a full sales intelligence platform -- strictly contact data.
• Best fit: Teams that already have a prospecting workflow (like AI email tools or a SEP) and just need a reliable, affordable way to fill in missing email addresses and phone numbers.

Pricing Comparison at a Glance

Here is a quick reference for budgeting. All prices reflect annual billing where applicable.

• Under $1K/year (per user): FullEnrich ($29/mo), Lusha Pro ($22.45/user/mo), Apollo Basic ($49/user/mo)
• $1K-$15K/year: Apollo team plans, Seamless.AI Basic, Lusha Premium/Scale, SalesIntel Individual, Clay Starter
• $15K-$30K/year: ZoomInfo Professional, Cognism Platinum/Diamond, SalesIntel Team
• $30K-$60K/year: ZoomInfo Advanced/Elite, SalesIntel Enterprise, Clay Pro (at scale)
• $60K+/year: 6sense, ZoomInfo Enterprise, Clearbit/Breeze at high volume

The per-verified-contact cost also varies significantly. One 2026 analysis calculated Apollo at approximately $0.47 per verified contact, ZoomInfo at $0.62, and Clearbit at $0.71 -- though these numbers depend heavily on usage patterns and verification rates.

Decision Framework: Which Platform Fits Your Team?

Instead of asking "which platform is best," ask these four questions:

What is your primary enrichment need?

• Email addresses for outbound sequences: Apollo, FullEnrich, or Lusha
• Phone-verified mobile numbers for cold calling: Cognism or SalesIntel
• Full account intelligence (firmographic + technographic + intent): ZoomInfo or 6sense
• Maximum coverage across multiple providers: Clay or FullEnrich
• Native CRM enrichment without adding tools: Clearbit/Breeze (HubSpot)

What is your annual budget?

• Under $5K: Apollo, Lusha, FullEnrich, or Seamless.AI
• $5K-$25K: Apollo (team), Cognism, SalesIntel, or Clay
• $25K+: ZoomInfo, 6sense, or multi-tool stack

Where do your prospects sit geographically?

• North America-focused: ZoomInfo or Apollo
• Europe/EMEA-focused: Cognism
• Global: ZoomInfo (breadth) or Clay (multi-provider coverage)

How technical is your RevOps team?

• Want plug-and-play: Lusha, Apollo, Seamless.AI
• Can build workflows: Clay, FullEnrich
• Full RevOps team with engineers: Clay + multiple APIs, 6sense

The Waterfall Enrichment Strategy

One increasingly common approach is waterfall enrichment -- using multiple providers sequentially rather than betting everything on one. If Provider A cannot find an email address, the system automatically queries Provider B, then C, and so on.

Industry benchmarks show single-provider enrichment achieves 30-60% match rates, while waterfall approaches push that to 80% or higher. Some teams report 93-94% completion rates with well-tuned waterfalls. Clay and FullEnrich are purpose-built for this. You can also build a DIY waterfall using APIs from Apollo, Lusha, and other providers -- tools like Clay or even custom scripts make this feasible.

The trade-off is cost and complexity. Each provider in the chain adds credits consumed per record. For a team enriching 10,000 contacts per month, a 3-provider waterfall might cost 2-3x what a single provider would. Run the math on your expected match rates before committing. The Clay credits calculator can help estimate costs for specific waterfall configurations.

What Data Enrichment Cannot Do

Enrichment solves the "who to contact" problem. It does not solve the "what to say" problem. A verified email address, company size, and tech stack get you to the door. Crafting a message that earns an open, read, and reply requires a different layer -- one built on buying signals, timing, and personalization.

This is where signal-based selling complements data enrichment. Knowing that a company just posted three DevOps job openings, raised a Series C, or switched from a competitor product gives you context to write outreach that resonates. Tools like Autobound layer signal intelligence on top of enriched contact data, turning a verified email into a warm, relevant conversation starter. For teams already using a contact database provider, adding a signal layer is the fastest way to improve reply rates without changing your enrichment stack.

The most effective GTM stacks pair a strong enrichment provider (for accurate contact data) with a signal layer (for timely context) and a delivery mechanism (SEP, email, LinkedIn). Enrichment is the foundation, but it is not the full building.

Implementation Checklist

If you are evaluating data enrichment platforms right now, here is a practical 4-week plan:

1. Week 1 -- Audit your current data. Export a sample of 1,000 CRM records. Check email validity with a free tool like NeverBounce or ZeroBounce. Identify what percentage of records are missing emails, phone numbers, titles, or company data. This baseline measures improvement.
2. Week 2 -- Run parallel trials. Most platforms listed here offer free tiers or trials. Enrich the same 200-500 records across 2-3 platforms and compare: match rate, accuracy (spot-check 50 records manually), field coverage, and ease of use.
3. Week 3 -- Calculate true cost. Based on trial results, project your monthly credit consumption at full scale. Factor in per-seat costs, overage rates, and add-ons (intent data, API access). Compare the effective cost per usable enriched record, not just the sticker price.
4. Week 4 -- Integrate and monitor. Connect your chosen platform to your CRM. Set up automated enrichment rules (enrich all new leads on creation, re-enrich existing records quarterly). Build a data quality dashboard tracking bounce rates, enrichment coverage, and record completeness over time.

The Bottom Line

There is no single "best" data enrichment platform. ZoomInfo is the safest enterprise bet. Apollo is the best value for outbound teams. Cognism owns European data quality. Clay maximizes coverage through orchestration. Lusha and FullEnrich get the job done at the lowest price point.

The real competitive advantage is not which database you subscribe to -- it is how quickly and accurately you can turn enriched data into relevant, timely outreach. Start with the platform that fits your budget and primary use case, measure what matters (deliverability, reply rate, pipeline generated), and expand from there.
