1. 1

   Apollo.io

   B2B contact database with built-in sequencing, dialer and deal tools on one credit-based plan.

   9.2overall

   B2B contact database with built-in sequencing, dialer and deal tools on one credit-based plan.

   Best forOutbound teams that want data and email sequences in one tool at a low seat price

   Adoption data

   600,000Apollo.io says more than 600,000 companies use its platform.

   Apollo.io, Apollo.io homepage (2026): “Over 600,000 companies use Apollo to help stay ahead of the competition.”

   Apollo.io gives the most data per dollar among the tools with public prices. The Basic plan costs $49 per seat per month on annual billing and grants 30,000 credits per seat a year upfront, while Professional at $79 raises that to 48,000 credits and adds more automation. A permanent free plan includes 900 credits per seat a year, enough for a founder to test the database of 240M+ contacts and 30M+ accounts before paying. Sequencing is included on every account, so many small teams use Apollo.io as both their data source and their outreach tool. The company says more than 600,000 companies use it, the highest adoption figure we found among dedicated databases. Limits are real: free accounts connect only Gmail, the Organization plan needs a minimum of 3 seats, and its published contact count is smaller than several rivals. We compared documented features and published prices on Apollo.io's own pages and did not run hands-on tests.

   Strengths

   • +Permanent free plan with 900 credits per seat a year
   • +Basic seat includes 30,000 credits a year
   • +Largest published company count on this list

   Limitations

   • −Free plan connects Gmail accounts only
   • −Organization plan requires at least 3 seats
   • −Smaller published contact count than Lusha, ZoomInfo or RocketReach

   SummaryApollo.io ranks first because it combines a free plan, a cheap credit-rich Basic seat and the largest published user base here. Check its coverage in your niche against a larger database before you commit.

2. 2

   Lusha

   Verified B2B contact and company data with a browser extension, CRM integrations and an MCP connector.

   8.5overall

   Verified B2B contact and company data with a browser extension, CRM integrations and an MCP connector.

   Best forSmall sales teams that want a large verified database and a simple credit system

   Adoption data

   280,000Lusha says more than 280,000 go-to-market teams worldwide use its data.

   Lusha, Lusha homepage (2026): “Trusted by 280,000+ GTM teams worldwide”

   Lusha is the easiest database here to budget for. Its pricing page spells out the credit rules: revealing a verified email costs 1 credit and a phone number costs 5, so a team can estimate spend from its outreach mix. The free plan gives 40 credits a month with the browser extension and CRM integrations, and Starter costs $37.45 a month billed yearly with 4,800 credits granted upfront and one seat included. Lusha says its search covers 515M+ verified contacts and 29M+ companies with 77 fields per record, the second largest contact count we found, and it reports more than 280,000 GTM teams as users. Newer Deep Intelligence features score accounts against your ideal customer profile and surface buying signals. The weak spot is volume: 4,800 credits a year runs out fast for a phone-heavy team, and the API, CSV enrichment and webhooks start on the $52.45 Pro plan with 7,200 credits a year. We compared documented features and published prices on Lusha's own pages and did not run hands-on tests.

   Strengths

   • +Permanent free plan with 40 credits a month
   • +Second largest published contact count on this list
   • +Clear credit costs: 1 per email, 5 per phone number

   Limitations

   • −Starter includes only 4,800 credits a year
   • −Phone reveals cost five times as much as emails
   • −API and CSV enrichment start on the $52.45 Pro plan

   SummaryLusha ranks second for its large verified database, clear credit math and a cheap Starter plan. Phone-first teams should price out Pro or Premium before committing.

3. 3

   Clay

   Data enrichment workspace that combines 150+ providers and an AI research agent in spreadsheet-style tables.

   8.4overall

   Data enrichment workspace that combines 150+ providers and an AI research agent in spreadsheet-style tables.

   Best forGTM engineers and RevOps teams that build custom enrichment workflows

   Adoption data

   500,000Clay says more than 500,000 go-to-market teams use its platform.

   Clay, Clay homepage (2026): “Trusted by more than 500,000 leading GTM teams of all sizes.”

   Clay is not a contact database in the usual sense. It is a workspace that queries 150+ data providers, runs them in waterfalls until it finds a match, and lets Claygent, its AI agent, research custom data points on the web. That makes it the most flexible tool here for teams with a RevOps or GTM engineer who can design workflows. The free plan includes unlimited seats and tables, waterfalls and 1,200 data credits a year, but no phone enrichment. Launch costs $167 a month and starts at 180,000 actions and 30,000 data credits a year, and Growth at $446 a month adds CRM auto-sync. Clay reports more than 500,000 GTM teams as users. The cost model is its weakness for simple prospecting: two separate meters, actions and data credits, make spend harder to predict than a flat per-contact credit. We compared documented features and published prices on Clay's own pages and did not run hands-on tests.

   Strengths

   • +Combines many data sources instead of relying on one database
   • +Free plan with unlimited seats
   • +Highly flexible workflows for custom data points

   Limitations

   • −Launch starts at $167 a month
   • −Separate action and data credit meters take planning
   • −Free plan does not include phone number enrichment

   SummaryClay is the best choice when you want to combine many data sources and build custom enrichment. Reps who just need a contact lookup will pay less elsewhere.

4. 4

   RocketReach

   People and company lookup tool with verified emails, phone numbers and a contact data API.

   8.4overall

   People and company lookup tool with verified emails, phone numbers and a contact data API.

   Best forIndividuals and recruiters who need a large global lookup at the lowest verified price

   Adoption data

   26 millionRocketReach says more than 26 million users and 95 percent of the S&P 500 use its service.

   RocketReach, RocketReach homepage (2026): “Trusted by over 26 million users and 95% of the S&P 500.”

   RocketReach is the cheapest way into a large database on this list. Essentials costs $19 a month, or $229 billed annually, and includes unlimited verified personal and professional emails with 1,200 exports a year, up to 500 emails a day and MCP and API access. Phone numbers start on Pro at $52 a month billed annually, which adds unlimited verified mobile and direct numbers, 3,600 exports a year, technographics and CRM integrations with Salesforce, HubSpot, Outreach, Salesloft and Bullhorn. The vendor claims 700M profiles and 60M companies, the largest profile count we found, and reports more than 26 million users. The tradeoff is depth of sales tooling: RocketReach is a lookup and export tool more than a full prospecting suite, and larger teams are pushed to custom packages that start at $6K a year. We compared documented features and published prices on RocketReach's own pages and did not run hands-on tests.

   Strengths

   • +Cheapest verified paid entry on this list at $19 a month
   • +Largest published profile count here
   • +MCP and API access from the Essentials plan

   Limitations

   • −Essentials covers email only, no phone numbers
   • −Essentials caps exports at 1,200 a year
   • −Team plans start at $6K a year through sales

   SummaryRocketReach is the value pick for individuals who mostly need emails from a very large profile base. Teams that call prospects should budget for Pro.

   LinkedIn Sales Navigator

   Advanced search, lead lists and InMail on top of LinkedIn's professional network.

   8.3overall

   Advanced search, lead lists and InMail on top of LinkedIn's professional network.

   Best forAccount executives who prospect through LinkedIn profiles and relationships

   Adoption data

   1 billionLinkedIn reports more than 1 billion members in more than 200 countries and territories, the network Sales Navigator searches.

   LinkedIn, About LinkedIn (2026): “the world's largest professional network with more than 1 billion members in more than 200 countries and territories worldwide”

   Sales Navigator is the tool most reps already know, because it sits on top of LinkedIn's network of more than 1 billion members. It adds advanced lead and account search, saved lists, 50 InMails a month and Relationship Explorer and Relationship Map for finding warm paths into an account; LinkedIn positions Advanced for teams that need collaboration tools. Core costs $119.99 per license per month, or $1,079.88 a year, which LinkedIn says is a 25 percent saving, and Advanced costs $159.99 a month or $1,799.88 a year. CRM connections to Salesforce, HubSpot and Microsoft Dynamics let reps create leads without manual entry. What it does not do is sell contact data: there are no email addresses or phone numbers to export, so most teams pair it with one of the databases on this list. That makes its value score lower than the dedicated tools, even with the top adoption figure. We compared documented features and published prices on LinkedIn's own pages and did not run hands-on tests.

   Strengths

   • +Searches the largest professional network
   • +Profiles are kept current by members themselves
   • +Annual billing saves 25 percent on Core

   Limitations

   • −Does not supply email addresses or phone numbers
   • −Highest verified entry price on this list
   • −Advanced Plus pricing is quoted only by sales

   SummarySales Navigator is the best way to search and research people on LinkedIn, and most teams will still need a separate source for emails and phones. Pick Core unless your team needs Advanced collaboration tools.

6. 6

   ZoomInfo

   Enterprise GTM platform with B2B contact and company data, intent signals and sales engagement.

   8.3overall

   Enterprise GTM platform with B2B contact and company data, intent signals and sales engagement.

   Best forUpmarket sales and marketing teams that need deep company coverage and buying signals

   Adoption data

   1,851ZoomInfo reported 1,851 customers with $100,000 or more in annual contract value at the end of the third quarter of 2026.

   ZoomInfo Technologies Inc. (SEC Form 8-K, Exhibit 99.1), ZoomInfo third quarter 2026 financial results (2026): “the Company closed the quarter with 1,851 customers with $100,000 or greater in ACV”

   ZoomInfo has the most complete feature set and the deepest company data of the products we compared. It reports 500M+ contacts and 100M+ companies, including 34M+ companies and 200M+ professionals outside North America, and its GTM Studio checks 25+ data sources at once to return the highest-confidence match. On top of the data it sells account-based marketing, website visitor identification and lead routing, with 20+ native integrations. The company says it has a permanent free plan with no credit card, and paid use runs on custom packages with consumption credits. That is the problem for comparison shoppers: there are no list prices, so the value score stays low until you have a quote. Its third quarter 2026 filing reported 1,851 customers paying $100,000 or more a year, which shows enterprise depth rather than total users. We compared documented features on ZoomInfo's own pages and its SEC filing and did not run hands-on tests.

   Strengths

   • +Largest published company count on this list
   • +Broad platform covering data, intent and engagement
   • +Permanent free plan for testing the data

   Limitations

   • −No published list prices
   • −Custom packages require a sales process
   • −Adoption figure counts only its largest customers

   SummaryZoomInfo is the strongest platform for upmarket teams that need breadth of company data and signals. Get a quote and test coverage in your territory before signing.

   Cognism

   Compliance-focused B2B contact data with verified mobile numbers, intent signals and CRM enrichment.

   7.3overall

   Compliance-focused B2B contact data with verified mobile numbers, intent signals and CRM enrichment.

   Best forSales teams of five or more selling into Europe that prioritize compliant mobile data

   Adoption data

   4,000Cognism says more than 4,000 companies worldwide use its data.

   Cognism, Cognism Pricing (2026): “Trusted by 4000+ companies worldwide”

   Cognism sells data built around compliance and mobile numbers. Both plans, Standard and Pro, include 5 seats, so it is aimed at teams rather than individuals. Standard covers firmographic, technographic and signal-based search, AI account research, CSV enrichment and MCP and API access. Pro adds premium mobile data, on-demand mobile verification and intent data. The credit rules are among the clearest here: 1 credit reveals a contact, viewing a contact you already revealed is free, and the same credits work across prospecting, the Enrich product and the API. CRM Enrichment is an add-on on both plans. Cognism does not publish prices, so we kept its value score low, and its reported base of 4,000+ companies is smaller than the self-serve tools. We compared documented features on Cognism's own pages and did not run hands-on tests.

   Strengths

   • +Clear credit rule: 1 credit per revealed contact
   • +No charge for viewing contacts already revealed
   • +Same credits work across the platform, Enrich and API

   Limitations

   • −No published prices
   • −Plans include 5 seats, a poor fit for solo users
   • −Intent data and mobile verification need the Pro plan

   SummaryCognism fits teams that call prospects in Europe and want verified mobiles with a clear credit rule. Ask for a quote early, since every plan starts at 5 seats.

   UpLead

   B2B lead database with real-time email verification, mobile numbers and intent data on credit plans.

   7.3overall

   B2B lead database with real-time email verification, mobile numbers and intent data on credit plans.

   Best forSmall teams that want verified leads on a short trial before buying credits

   Adoption data

   4,000UpLead says more than 4,000 businesses use its data.

   UpLead, UpLead homepage (2026): “Trusted By 4,000+ Businesses”

   UpLead keeps credit pricing simple: one credit unlocks one contact for download or CRM export and includes both the email and the mobile direct dial. Essentials costs $74 a month on annual billing with 2,040 credits, or $99 a month on monthly billing with 170 credits, and Plus costs $149 a month billed annually with 4,800 credits. A 7-day trial with 5 credits lets you check data quality first. The vendor says it has 200M+ leads that it verifies as you search, and it integrates with Salesforce, HubSpot, Outreach, Salesloft and other sales tools, plus 1,500+ apps through Zapier. The limits show in scale: its database and its customer count of 4,000+ businesses are both smaller than the leaders here, and there is no free plan. For a small team that wants verified emails and mobiles on a predictable per-contact cost, it is a reasonable fit. We compared documented features and published prices on UpLead's own pages and did not run hands-on tests.

   Strengths

   • +Simple rule: one credit equals one contact
   • +Email and mobile included in each credit
   • +Monthly plans available, not only annual

   Limitations

   • −No permanent free plan, only a 7-day trial
   • −Smallest published customer count on this list
   • −Smaller published database than most rivals

   SummaryUpLead suits small teams that want email and mobile in one credit with no surprises. Teams that need volume will get more credits per dollar from Apollo.io.
