Free Email Finders and B2B Lead Data
Which email finders, contact databases and company signal tools give you contacts for free today, how many, what a credit gets and what the first paid plan costs, read from each tool's own page.
Free allowances read on each provider's own pages, all checked on or after . Lead data tools change their free credits and plans often: confirm the terms on the tool's page before you plan a campaign on them.
Email finders and lead data tools you can use for free today include Apollo.io (900 credits a year, granted monthly), Tomba (25 searches every 30 days), TheirStack (50 company and 200 API credits a month), Lusha (40 credits a month), and Enrow (50 free credits). Each of the 14 free allowances below links to the tool's page that states it, with its main limit, what a credit gets and what the first paid plan costs.
Lead data tools find the people and companies a founder wants to reach: a person's work email from a name and a domain, contacts filtered by role and industry from a database, or companies by the technology they use or the visits they make to your website. Most let you start free, with credits every month or a one-time amount.
The headline number rarely tells you how far it goes. A credit can buy an email but several credits a phone number, free credits can expire at the end of a cycle or a 7-day trial, and a free plan can cap search results. Each tool below shows its free allowance, its main limit, what a credit gets and what the first paid plan costs, quoted from the tool's own page with the date we read it.
Which tools we picked and the order they appear in are our editorial choices; the terms are the tools'. Several of these tools pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

Startup programs for lead data
Programs from lead data providers that give startups discounts or credits. Most ask for an application, and several for funding or a partner investor.
Also useful for sales and outreach
Shown only because they fit what this page is about, and ordered by that fit (70%) and what a referral is expected to earn us (30%). We may earn a commission if you sign up through one of these, at no cost to you. They never change the ranking of this page.
Compare the top options
How this comparison is built
The list covers email finders, contact databases and company signal tools a founder can use for free today without applying to a program, grouped by the job they do. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or documentation page on the date shown, never from a third-party list; follow each link for the full conditions. What a credit gets (an email, a phone number, a company) and whether free credits expire can matter more than the headline, so the comparison quotes them wherever the tool states them. Use any of these only within the law that applies to you, and email only people you have a lawful reason to contact. Several of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that never decides whether or where a tool appears, and no tool pays for a placement on this page.
Read the full methodologyCommon questions
What is the best free email finder?
It depends on how many you need. By the terms each tool states, Tomba gives 25 searches every 30 days with no card and charges nothing for a search that finds nothing, Enrow and Voila Norbert give 50 free credits to start, and Apollo.io grants 900 credits a year on its free plan, where an email costs 1 credit and a phone number 8.
Is Apollo.io free?
Yes. Apollo's free plan grants 900 credits a year per seat, given monthly; an email costs 1 credit and a phone number 8, and unused credits expire at the end of each cycle. Its Basic plan is $49 a seat a month billed yearly, with 30,000 credits a year.
Do free lead data tools need a credit card?
Most of the free allowances here need none: Lusha, Wiza, Enrow, SignalHire, BookYourData, Tomba, Grape Leads, Leadfeeder, ColdIQ and RichAPI's sandbox say so on their own pages. Anymail Finder's 7-day trial checks a card without charging it.
How can I see which companies visit my website for free?
Leadfeeder's free Lite plan identifies the last 100 companies a month that visit your website, with a 7-day history and unlimited users. It identifies companies from your traffic, not the people who visited.
Can I email the people these tools find?
Only within the law that applies to you and to them. In the US, CAN-SPAM requires an accurate sender and a working way to opt out; in the EU and UK, GDPR and the e-privacy rules set stricter conditions on contacting people. Email only people you have a lawful reason to contact, and honor every opt-out.
