How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- Apollo.io is the value pick: a free Starter plan with no time limit plus a database, sequences, and dialer in one, with paid tiers on published per-seat pricing.
- ZoomInfo remains the data heavyweight (500M+ contacts, intent data), now with a permanent free Lite plan; its consumption-based pricing rewards careful credit management.
- UpLead ($99/month) and RocketReach (from $34/month) are the transparent-priced options with published plans and free starting points.
- SalesIntel drops the credit system entirely with flat-fee unlimited data; Cognism is the compliance-first choice for European prospecting.

The best sales leads software
Every sales team eventually does the same math. A rep spends hours hunting for contact details, half the emails bounce, and the "database" the company bought two years ago has decayed into guesswork. The best sales leads software fixes the top of the funnel: verified emails and phone numbers, company data, buying signals, and a way to get it all into the CRM without manual copying.
The market splits into two camps. Database platforms (ZoomInfo, Apollo, Lusha, Cognism, UpLead, SalesIntel, RocketReach) maintain huge contact indexes you search and filter. Workflow tools (LeadIQ, and Apollo's engagement side) focus on capturing prospects where reps already work, usually LinkedIn, and pushing them into sequences. Most teams end up with one of each. These nine cover both camps, with pricing you can actually verify.
#1
Apollo.io
Best for: Solo sellers and small teams that want the database and the outreach in one login
Visit apollo.io
Starting priceSee website (Free, Basic, Professional, and Custom tiers; per-seat pricing)
Free planYes (free Starter plan with no time limit)
Apollo is the reason this category has a budget option. Where competitors start with a sales call, Apollo lets a founder sign up free and start prospecting the same day, then grow into paid seats as the team grows. The platform covers the full motion: find contacts, enrich them, run sequences, dial, and sync everything to the CRM. For small teams, replacing two or three point tools with one Apollo subscription is the whole pitch.
The honest catch is the credit economy. Every email reveal, phone number, and export draws from a pooled credit balance that resets each cycle and does not roll over, so heavy months need planning or add-on credit purchases. Data quality is strong on emails and weaker on direct dials than Lusha or Cognism. And plan mixing is not allowed: if one rep needs Professional, everyone moves to Professional.
What we like- 240M+ contacts and 30M+ accounts with 200+ integrations
- Genuinely useful free plan for testing real prospecting
- Built-in email sequences, dialer on paid tiers, and deliverability tools
- AI agents for research and list building
Watch out for- The credit system takes time to understand and budget
- Phone-number accuracy trails the phone-first specialists
- Every seat on an account must sit on the same plan
#2
ZoomInfo
Best for: Mid-market and enterprise revenue teams that run on data depth and intent signals
Visit zoominfo.com
Starting priceFree to start; consumption-based credits (see ZoomInfo pricing for current details)
Free planYes (ZoomInfo Lite is a permanent free plan, no credit card required)
ZoomInfo is the incumbent every other tool on this list positions against. The dataset is the deepest, the intent data is the most mature, and the platform now stretches from prospecting to AI agents that run full go-to-market plays. The surprise is the free entry: ZoomInfo Lite is a permanent free plan with no credit card, and the company now prices on consumption credits rather than fixed seat tiers, so small teams can start without an enterprise contract.
The honest catch is cost control. Consumption pricing means the bill scales with usage, which is fair until a rep burns credits on broad exports. Annual contracts with 30-day cancellation notice windows are the norm on paid tiers. And while the data is the best in aggregate, no database is perfect: always verify a sample in your niche before committing.
What we like- The largest B2B dataset here: 500M+ contacts and 100M+ companies
- Intent data, org charts, and technographics in one platform
- 120+ integrations including Salesforce, HubSpot, Outreach, and Salesloft
- AI agents and a GTM Context Graph for account research
Watch out for- Consumption pricing can get expensive fast if credits are not managed
- The full platform is overkill for a five-person sales team
- Niche-title accuracy still draws complaints from reviewers
#3
Lusha
Best for: Reps who live on LinkedIn and need verified emails and phone numbers in one click
Visit lusha.com
Starting priceSee website
Free planYes (free plan available, no credit card required; limits on the pricing page)
Lusha built its name on a single interaction: open a LinkedIn profile, click the extension, get the email and phone number. That workflow is still the best in the category for speed, and the company backs its data with unusual transparency, publishing hit rates, sample sizes, and how fast records go stale. The 515M-contact database and 26 weekly-refreshed buying signals make it a legitimate prospecting platform, not just a browser trick.
The honest catch is scope. Lusha finds people and enriches records; it does not send your sequences or manage your pipeline, so you will pair it with an outreach tool. Credit limits mean heavy prospectors need a paid tier, and the pricing page holds the exact numbers. For phone-first outbound teams, though, few tools deliver numbers this fast.
What we like- 515M+ verified contacts with 26 buying signals
- The Chrome extension is the fastest LinkedIn-to-contact workflow here
- Publishes its accuracy methodology and test results
- API and MCP access for teams and AI agents
Watch out for- Credit-based pricing with limits on the free tier
- Company-level data is thinner than ZoomInfo's
- It enriches and finds contacts but does not run your outreach sequences
#4
Cognism
Best for: Revenue teams selling into Europe where compliance is non-negotiable
Visit cognism.com
Starting priceSee website (custom quote)
Free planNo (demo available)
Cognism is the answer to a specific, expensive problem: prospecting in Europe without tripping over GDPR. The platform combines verified emails with phone-verified mobile numbers, refreshed on a 30-day cycle, and wraps it in compliance tooling (opt-out and DNC suppression) that US-built databases treat as an afterthought. For teams whose pipeline depends on connecting with European decision-makers by phone, the verified-mobile focus is the differentiator.
The honest catch is the buying experience. There is no price list, no free plan, and no self-serve signup: you talk to sales, you get a custom annual quote. That is normal for enterprise data vendors, but it makes comparison shopping slow. US-heavy teams should test coverage in their territories first, since Cognism's depth is Euro-centric.
What we like- Phone-verified mobile numbers (Diamond Data) with up to 3x higher connect rates claimed
- Compliance-first posture with GDPR, CCPA, and European DNC coverage
- The strongest European data coverage on this list
- Bombora intent data and a Chrome extension for LinkedIn workflows
Watch out for- No published pricing and no free tier: every deal starts with sales
- US data depth trails the US-native vendors
- Premium positioning means premium quotes
#5
Seamless.AI
Best for: Founders and SDRs who want real-time contact lookup without committing to a database subscription
Visit seamless.ai
Starting priceFree for up to 50 credits; paid plans are quote-based via sales
Free planYes (50 free credits to start)
Seamless.AI takes a different technical approach: instead of selling access to a stored database, its engine searches the web in real time when you look up a prospect. The pitch is freshness: a record verified seconds ago beats one verified months ago. The company backs that with 100% credit-back protection on invalid emails and a free tier of 50 credits that lets you test the approach before spending anything.
The honest catch is pricing opacity. Beyond the free credits, everything runs through sales, so you cannot budget from the website. The real-time model also means results depend on what is publicly findable about a prospect, which favors well-documented professionals over niche titles. Try the free credits on your actual ICP before committing.
What we like- Real-time AI search that verifies contacts at lookup time instead of serving stale database records
- Credit-back protection automatically refunds credits for invalid emails
- Free tier is genuinely usable for testing
- API available on every plan including free
Watch out for- Paid pricing is entirely sales-led with no public tiers
- Accuracy varies more by niche than with curated databases
- The product has expanded into a full revenue platform, which adds complexity for pure prospecting use
#6
UpLead
Best for: Small teams that want verified B2B emails with a price they can see before talking to sales
Visit uplead.com
Starting price$99/month (Essentials plan, 170 credits/month)
Free planFree trial (7 days, 5 credits)
UpLead is the anti-enterprise pick: published prices, a 7-day free trial, and month-to-month billing. The 95% accuracy guarantee is the core promise, backed by real-time verification and credit refunds when data fails. At $99 a month for 170 credits, a solo seller or small agency gets a predictable prospecting budget without a procurement cycle.
The honest catch is scale. The contact universe is smaller than the giants, and the plan structure pushes teams toward the custom-quoted Professional tier once you need multiple seats, intent data, or API access. For individual prospectors and small teams, though, it is the most straightforward buying experience on this list.
What we like- Fully published pricing starting at $99/month with no sales call required
- 95%+ data accuracy guarantee with credit refunds for bad data
- Real-time email verification on every export
- No long-term contracts on monthly plans
Watch out for- 200M contacts is a smaller universe than ZoomInfo or Apollo
- Buyer intent data sits on the top Professional tier
- Essentials and Plus are single-user plans, so teams must step up to Professional
#7
RocketReach
Best for: Sales and recruiting teams that want lookup-first prospecting at a low entry price
Visit rocketreach.co
Starting price$34/month (entry subscriptions start at $34/month per RocketReach's own site)
Free planYes (5 free lookups, no credit card required)
RocketReach is the workhorse of lookup prospecting. Type a name or filter by title, industry, and location, click to reveal, and get graded contact details with real-time verification. The pricing starts lower than almost everything else here, and the free account with 5 lookups lets anyone test accuracy on their own prospects. Recruiters use it as heavily as sales teams, which says something about the data breadth.
The honest catch is the tier ladder. The cheap entry tier covers email lookups; phones, bulk exports, CRM sync, and the API climb the tiers quickly. A lookup is only charged when it returns a verified result, which is fair, but heavy users should model their monthly lookup volume against the tier limits before choosing. For straightforward "find this person's email" work, it is hard to beat on price.
What we like- 700M profiles and 60M companies, one of the largest lookup indexes
- Graded emails and phone numbers with stated deliverability ranges
- Entry pricing far below the enterprise vendors
- Trusted by 26M+ users including most of the S&P 500
Watch out for- Lookup and export limits tighten on cheaper tiers
- CRM integrations start on the Pro tier
- Intent data and advanced features are gated to the top Ultimate tier
#8
SalesIntel
Best for: Teams tired of credit math that want one flat fee for unlimited prospecting data
Visit salesintel.io
Starting priceSee website (one flat fee for unlimited data; custom quote)
Free planNo (demo available)
SalesIntel's pitch is one sentence: one fee, unlimited data. No credit pools, no per-seat metering of lookups, no mid-quarter overage purchases. Underneath that sits a 200M-contact database that 2,000+ human researchers re-verify on a 90-day cycle, with 95% accuracy claimed and 54M+ verified mobile numbers. For RevOps leaders who want a forecastable line item, the model is refreshing.
The honest catch is that "simple pricing" still means a sales quote: there is no public number. The platform has also grown into sequencing, dialing, and ads, which is either a bonus or bloat depending on your stack. Evaluate it against your current credit spend: if your team routinely buys top-ups, the flat fee usually wins.
What we like- Unlimited data access with no credits to count or top up
- 200M+ contacts re-verified every 90 days by 2,000+ human researchers
- 60,000+ intent topics via PredictiveIntent and Bombora
- Free RevDriver Chrome extension for LinkedIn prospecting
Watch out for- Pricing is quote-only despite the simple model
- The full platform has a learning curve for new users
- A smaller brand than ZoomInfo, so peer references take more digging
#9
LeadIQ
Best for: SDR teams that prospect inside LinkedIn Sales Navigator all day
Visit leadiq.com
Starting priceSee website
Free planNo (demo available)
LeadIQ does not try to be your database. It sits where your SDRs already work, LinkedIn and Sales Navigator, and turns profile views into CRM-ready prospects with verified contact data in one click. The Scribe AI personalization and real-time champion tracking (pinging you when a past champion moves companies) are the features teams cite when they renew. Used by 20,000+ sales professionals, it is the specialist's choice for outbound workflow.
The honest catch is the dependency. Without LinkedIn Sales Navigator in your stack, much of the value evaporates, and you will still need a data source behind it for net-new list building. Pricing is quote-based. Buy it to make an existing outbound motion faster, not to replace your contact database.
What we like- One-click capture from LinkedIn and Sales Navigator straight into CRM and sequences
- Scribe AI writes personalized outreach at scale
- Champion tracking alerts you when past buyers change jobs
- Deep integrations with Salesforce, Outreach, Salesloft, and Gong
Watch out for- A workflow and capture tool first, not a standalone contact database
- No published pricing
- The full value assumes your team already pays for Sales Navigator
How lead software is priced: credits, seats, and flat fees
Three pricing models dominate this category, and misunderstanding them is the most expensive mistake buyers make. Credit systems (Apollo, Lusha, Seamless.AI, UpLead, RocketReach) charge per reveal or export: one credit usually equals one email or phone number. They look cheap until a rep burns hundreds of credits on broad lists. Always ask what costs a credit, whether credits roll over (most do not), and what happens at the limit.
Seat pricing (Apollo's paid tiers, LeadIQ, Cognism) charges per user per month, sometimes with credit pools attached. It is predictable but punishes teams with mixed usage: Apollo puts every seat on the same plan, so one power user can drag the whole team up a tier. Flat-fee unlimited (SalesIntel) removes the metering entirely for one annual number, which suits high-volume teams but requires a quote to evaluate.
Then check the contract mechanics. Annual billing typically saves 15 to 20% but locks you in for 12 months with no mid-term seat reductions at several vendors. Free plans and trials are genuinely useful here: Apollo's free Starter has no time limit, ZoomInfo Lite is permanent, and UpLead and RocketReach both let you test before paying. Run your real ICP through the free tier first. If the data is bad for your niche on the free plan, the paid plan will not fix it.
How to judge data accuracy before you buy
Every vendor claims high accuracy, and every vendor's numbers are measured differently, so treat marketing claims as a starting point, not evidence. The practical test is simple: take 50 contacts you already know (customers, past prospects, your own network), run them through each trial, and score what comes back. Check three things: did it find the person, is the email pattern right, and does the phone number connect.
Watch for the specific failure modes. Database vendors go stale: people change jobs, and a record verified a year ago is a bounce today. Real-time lookup tools (Seamless.AI) dodge staleness but depend on public findability. Phone numbers are the hardest field everywhere; email accuracy is consistently higher. Lusha deserves credit for publishing its methodology with sample sizes, which is more than most competitors offer.
Two structural points matter. First, accuracy varies by segment: US tech contacts are the best-covered humans on earth, while niche industries and non-US markets are thinner everywhere. Second, compliance is part of accuracy now: Cognism's GDPR-first approach and ZoomInfo's DNC handling are not just legal cover, they keep your sender reputation intact. A cheap list that burns your domain costs more than an expensive one that does not.
Frequently asked questions
What is sales leads software?
Sales leads software helps B2B teams find and contact potential buyers. It typically combines a contact database (emails, phone numbers, company data), search and filtering, data enrichment, and integrations that push leads into a CRM or outreach tool. Some platforms add sequencing, dialing, and intent data.
How much does sales leads software cost?
It ranges from free to thousands per month. Transparent options include RocketReach (from $34/month), UpLead ($99/month), and Apollo (free Starter; paid tiers per seat). ZoomInfo and SalesIntel use consumption or flat-fee models that require a quote, and Cognism and LeadIQ are quote-only. Budget for credits or seats plus any add-ons.
Which sales leads software has the best data accuracy?
No vendor wins everywhere; accuracy varies by segment and data type. ZoomInfo has the largest database, Lusha publishes its testing methodology, UpLead guarantees 95% accuracy with credit refunds, and Cognism phone-verifies mobiles. The reliable move is to test 50 known contacts on each free trial and score the results yourself.
Is there really free sales leads software?
Yes, with limits. Apollo's free Starter plan has no time limit, ZoomInfo Lite is a permanent free plan, Lusha offers a free plan without a credit card, Seamless.AI gives 50 free credits, RocketReach gives 5 free lookups, and UpLead has a 7-day trial. Free tiers are best for testing data quality in your niche before buying.
Do I need LinkedIn Sales Navigator too?
Not necessarily, but the workflow tools assume it. LeadIQ and Lusha's Chrome extension are built around LinkedIn prospecting, and their value drops without Sales Navigator. Database-first tools (ZoomInfo, Apollo, UpLead, SalesIntel, RocketReach, Cognism, Seamless.AI) work standalone. Many teams run one database plus one LinkedIn workflow tool.
Credits vs. unlimited data: which pricing model is better?
It depends on volume. Light prospectors (under a few hundred lookups a month) usually spend less on credit systems like UpLead or RocketReach. Heavy teams that burn thousands of lookups often save with SalesIntel's flat-fee unlimited model or Apollo's pooled credits. Model three months of your actual usage before choosing.
How we chose
We started with the categories buyers search: sales leads software, B2B lead database, sales prospecting tools, and lead generation software. For each candidate we opened the vendor's own homepage, checked prices and free tiers against the vendor's own published pages where they exist, and compared database size, data accuracy practices, and fit for different team sizes using public reviews on G2 and Capterra and practitioner discussion on Reddit. Where a price could not be verified on the vendor's own page we wrote "See website" rather than guessing. Kaspr was replaced by LeadIQ because Kaspr was acquired by Cognism.
