How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Apollo is the strongest all-in-one starting point for small and mid-size teams, with a free plan, a large contact database, and built-in outreach.
- Clay is the most flexible choice for teams that want to combine many data sources and AI research into custom prospecting workflows.
- ZoomInfo and Cognism suit larger teams that need broad coverage, intent signals, and compliance controls, and both price on request for full plans.
- Lusha and LeadIQ are the best low-friction options for reps who mainly need verified emails and phone numbers while working in LinkedIn or a CRM.
- Credit systems differ sharply between vendors, so compare how many contacts a plan really buys before comparing headline prices.

#1Apollo
Best for: Small and mid-size teams that want prospecting, data, and outreach in one place4.7/5 on
G2 (9,847 reviews, checked Oct 2026)
Visit apollo.io
Starting price$49 per user/month
Free planYes
Apollo covers the full early pipeline. Reps search a database of more than 240 million contacts and 30 million accounts, filter by title, industry, company size, and technology, then launch email sequences and calls from the same workspace. AI features research accounts, score prospects, and draft outreach, and buying signals such as job changes and website visits help reps time their first message.
The free plan makes Apollo easy to evaluate without a sales call. Paid plans start at $49 per user per month billed annually for Basic, with Professional at $79 and Organization at $119 per user per month on annual billing. The catch is credits. Prospecting credits are pooled and expire, so a team that burns through contacts in a busy month cannot always roll the balance forward. Apollo still wins on breadth for the price, but teams should size credits against real monthly list volume before committing.
What we like- Large contact database, built-in sequences and dialer, free plan for trying core features
Watch out for- Credit limits can bite on higher-volume teams, advanced plans rise quickly in price
#2Clay
Best for: RevOps and growth teams building custom prospecting workflows4.6/5 on
G2 (234 reviews, checked Oct 2026)
Visit clay.com
Starting priceSee website
Free planYes
Clay is less a contact database and more a workbench. Users build tables of companies and people, enrich them from more than 200 data providers, run AI agents to research accounts and write personalised notes, and push finished lists to a CRM or outreach tool. That design suits teams with a clear ideal customer profile and repeatable plays, such as finding companies hiring for a specific role or tracking funding announcements.
Pricing is the reason this entry says See website. Clay overhauled its plans in early 2026, replacing older tiers with new Launch and Growth plans and a split between data credits and AI actions. Older articles still quote the retired Starter and Explorer prices, so any fixed figure copied from a third-party roundup risks being wrong. There is a free tier for trying the product. Teams that adopt Clay should budget for data credits separately from the subscription and expect a few weeks of setup before workflows run smoothly.
What we like- Access to many data sources in one table, AI research agents, strong automation options
Watch out for- Pricing changed in 2026, so older price lists are out of date, learning curve is steep for new users
#3ZoomInfo
Best for: Larger sales and marketing teams that need deep account intelligence4.5/5 on
G2 (9,130 reviews, checked Oct 2026)
Visit zoominfo.com
Starting priceSee website
Free planYes
ZoomInfo positions itself as a full go-to-market platform rather than a simple lead list. Its database covers more than 500 million contacts and 100 million companies, and its AI layer explains why an account is moving, using intent data, org changes, and engagement signals. Account research, meeting preparation, and deal prioritisation tools sit on top of that data.
ZoomInfo Lite is a permanent free plan with no credit card required, which gives small teams a way to try the data before talking to sales. Full platform pricing uses consumption credits rather than fixed seat tiers, so cost scales with how much data and how many workflows a team runs. That model can be fair for heavy users and confusing for buyers who want a simple per-seat figure. ZoomInfo fits best where data quality, coverage, and compliance documentation matter more than the lowest monthly bill.
What we like- Very large database, intent and signal data, strong CRM integrations
Watch out for- Full platform pricing is quoted, not published, can be expensive for small teams
#4Cognism
Best for: Teams selling into Europe that need phone-verified, compliant data4.5/5 on
G2 (1,365 reviews, checked Oct 2026)
Visit cognism.com
Starting priceSee website
Free planNo
Cognism built its name on premium sales intelligence with a European focus. Its data is refreshed regularly, mobile numbers go through extra verification steps, and the company stresses GDPR compliance and do-not-call coverage across Europe. For teams selling into the UK, France, Germany, and other European markets, that combination matters, because contact coverage and legal handling vary a lot by country. Intent signals and decision-maker data help reps prioritise accounts rather than working through long, cold lists.
There is no free plan, and pricing is quoted after a conversation with sales, so buyers should expect a longer evaluation than with self-serve tools. Cognism suits mid-market and enterprise teams with a clear European motion and a budget to match. Smaller teams that only need occasional lookups will usually get better value from Lusha or Apollo. The honest trade is coverage and compliance against cost and self-serve convenience.
What we like- Strong European coverage, phone-verified mobile numbers, compliance-first approach
Watch out for- No free plan, pricing is quoted, less suited to very small budgets
#5Lusha
Best for: Reps who need verified emails and phone numbers fast, often from LinkedIn4.3/5 on
G2 (1,668 reviews, checked Oct 2026)
Visit lusha.com
Starting price$37.45 per month
Free planYes
Lusha keeps prospecting close to where reps already work. A browser extension reveals contact details on LinkedIn and company websites, and the web platform adds search across more than 515 million contacts, buying signals, account scoring, and lookalike companies. Each email carries a confidence score and a last-update date, which helps reps judge whether a record is fresh.
Pricing is published and straightforward. The free plan includes a small monthly credit allowance, Starter costs $37.45 per month billed annually, Pro costs $52.45 per month billed annually, and Premium costs $299.95 per month billed annually. Credits are the detail to watch. An email typically costs one credit while a phone number costs five, so phone-heavy teams burn through allowances faster than the headline credit count suggests. For email-first prospecting and quick enrichment, Lusha remains one of the best value options on this list.
What we like- Simple browser extension, confidence scores on emails, dated buying signals
Watch out for- Phone numbers cost more credits than emails, free plan credits are limited
#6Seamless.AI
Best for: Reps who want real-time contact search rather than a static database4.4/5 on
G2 (5,394 reviews, checked Oct 2026)
Visit seamless.ai
Starting priceSee website
Free planYes
Seamless.AI takes a different approach from database vendors. Instead of selling access to a stored list, it searches the web in real time when a rep looks up a prospect, aiming to return the freshest contact details available. That can help in fast-moving segments where stored records go stale quickly. The company also offers credit-back protection, refunding credits automatically when an email turns out invalid, which removes some of the risk of paying for bad data. A Chrome extension turns the browser into a prospecting tool, and integrations cover major CRMs.
The free tier covers up to 50 credits, which is enough to test accuracy on a real list. Paid plans are quoted rather than published as a single price list, so this entry uses See website. Teams should test Seamless.AI against their own target accounts before buying, because real-time search quality depends on how much public information exists for a given industry and region. Where coverage is strong, it is a fast way to build lists. Where it is thin, a large database tool may serve better.
What we like- Real-time web search for fresh contacts, credit-back protection on invalid emails, Chrome extension
Watch out for- Paid pricing is not published as a simple list, accuracy varies by industry and region
#7LeadIQ
Best for: Sales teams that prospect mainly from LinkedIn and Sales Navigator4.2/5 on
G2 (1,186 reviews, checked Oct 2026)
Visit leadiq.com
Starting price$200 per month
Free planYes
LeadIQ is built around the rep workflow that starts on LinkedIn. Its browser extension captures contact details from profiles and Sales Navigator searches, then pushes prospects straight into Salesforce, Outreach, Salesloft, or a similar tool, often in one click. AI features draft personalised messages and track job changes so reps can re-engage champions who move companies.
Pricing has shifted, and older roundups still quote retired per-user tiers that no longer match the current site. Recent vendor material prices the Pro plan at $200 per month for up to five users, with a free tier offering a small monthly credit allowance. Teams should confirm current seat and credit limits on the pricing page before purchase, since the plan structure differs from the older model. For LinkedIn-heavy teams, the time saved on capture and syncing often justifies the price, but list builders who work mainly from databases may prefer Apollo or RocketReach.
What we like- Strong LinkedIn and Sales Navigator workflow, one-click capture to CRM and sequences, AI personalisation
Watch out for- Older low price tiers found online are out of date, best value comes with team plans
#8RocketReach
Best for: Teams that need broad contact search with email and phone coverage4.4/5 on
G2 (1,385 reviews, checked Oct 2026)
Visit rocketreach.co
Starting priceSee website
Free planYes
RocketReach combines a large database of more than 700 million profiles and 60 million companies with a browser extension, bulk lookup, and CRM integrations. Reps can search by title, company, location, and other filters, then reveal verified emails and phone numbers and export lists to Salesforce or HubSpot. AI recommendations and an AI message writer help with the next step after finding a contact, and an automation feature can run repeated discovery workflows without manual list building each week.
Pricing is the reason for See website here. Third-party pages quote several different price sets for the same plan names, reflecting changes over time, so a single figure copied from an old roundup would be unreliable. The free plan offers a small number of monthly lookups for testing. RocketReach suits teams that want a straightforward contact finder with broad coverage and do not need the workflow depth of Clay or the full platform scope of ZoomInfo. As with every credit-based tool, check how lookups and phone reveals are counted before comparing plans.
What we like- Large global database, browser extension, email and phone finder in one search
Watch out for- Published prices vary between sources, so the current price must be checked on the site
How we chose
We started from vendor pricing pages, product documentation, and feature lists, then checked those claims against public reviews on G2 and Capterra and discussion on Reddit. A tool made this list only if it is currently sold, offers AI-assisted prospecting or enrichment as a core feature, and fits a business-to-business sales use case. We favoured tools with published pricing where available and marked pricing as See website where vendors quote on request or where recent price changes made older figures unreliable. Company size fit mattered too. A tool that only makes sense for enterprise budgets did not displace a strong small-team option, and vice versa.
What to check before you buy
Start with your list, not the feature page. Write down your ideal customer in concrete terms, including industry, company size, geography, and buyer titles, then run the same test list through two or three tools on free or trial plans. Count how many records come back complete, how many emails are verified, and how many phone numbers you actually need. That test tells you more than any marketing claim about coverage, because databases differ by region and industry.
Next, read the credit rules as carefully as the price. Find out what counts as one credit, whether emails and phones cost the same, whether unused credits roll over, and whether AI actions are billed separately. A plan that looks cheap can become expensive when phone reveals cost five credits each or when AI research consumes a separate allowance. Ask vendors for a written summary of credit rules before signing an annual contract, and prefer monthly billing for the first quarter if the vendor allows it.
Compliance deserves the same attention as coverage. Prospecting rules differ by country and by channel, and business contact data still carries obligations around consent, opt-outs, and do-not-call lists. Check whether the vendor documents its data sources, offers suppression lists, and supports GDPR and CCPA requests. Teams selling into Europe should weight Cognism-style compliance handling more heavily, while US-focused teams should still confirm opt-out handling for email and calling. Finally, confirm the CRM integration works both ways. One-way exports create stale records, while two-way sync keeps enrichment, notes, and opt-outs consistent.
Frequently asked questions
What is an AI prospecting tool?
An AI prospecting tool helps sales teams find, enrich, and prioritise potential buyers. It searches contact and company data, scores leads by fit and buying signals, and often drafts outreach messages. Reps still qualify leads and run conversations, but the tool removes much of the manual research and list building that used to fill the start of the sales day.
Which AI prospecting tool is best for a small team?
Apollo is the safest starting point for most small teams, because it combines a large database, a free plan, and built-in outreach at a published price. Lusha is a strong alternative if the team mainly needs quick contact lookups from LinkedIn. Clay suits small teams only if someone on the team can own workflow setup, since its flexibility comes with a learning curve.
How much do AI prospecting tools cost?
Prices range from free plans with small credit allowances to quoted enterprise contracts. Published starting prices in this guide run from $37.45 per month for Lusha Starter to $200 per month for LeadIQ Pro for up to five users. All-in-one and enterprise platforms often cost more, and credit use can raise the real monthly cost above the headline subscription price.
Are the contact details from these tools accurate?
Accuracy varies by vendor, region, and industry, and no database is perfect. Vendors publish accuracy claims, but the reliable test is running your own target list through a trial and measuring bounce rates and wrong numbers. Tools that show confidence scores, last-update dates, or credit-back protection make that testing easier, because bad records cost less and are easier to spot.
Do I still need a CRM if I buy a prospecting tool?
Yes, in most cases. Prospecting tools find and enrich leads, while a CRM tracks conversations, deals, and customer history over time. Most tools on this list integrate with Salesforce and HubSpot, so enriched leads flow into the CRM instead of living in a separate spreadsheet.
Is AI prospecting legal?
AI prospecting is legal when it follows the rules that apply to business outreach in each market, including data protection law, consent requirements, and do-not-call rules. Vendors differ in how they source data and handle opt-outs, so teams should check vendor documentation and their own legal advice for the countries they target. Buying a tool does not remove the buyer's responsibility for how outreach is sent.
