About
Hunter.io is an email finder and domain search tool used by sales, marketing, and recruitment professionals to find professional email addresses for B2B outreach. Founded in 2015 and headquartered in Paris, France, Hunter.io is a bootstrapped company that has grown to over 4 million users without venture capital. Its Domain Search tool finds all email addresses associated with a given company domain, while the Email Finder tool generates a predicted email address for a specific person at a company based on the company's email format.\n\nHunter.io's core tool is its domain search — users input a company domain and receive a list of publicly findable email addresses at that organization along with a confidence score. The email verifier tool checks whether an address is likely deliverable before it is used in an outreach sequence, reducing bounce rates and protecting sender reputation. A Chrome extension enables email discovery directly from LinkedIn profiles and company websites.\n\nHunter.io has built its large user base through a freemium model that provides a limited number of monthly searches at no cost, converting active users to paid plans as their prospecting volumes grow. Its combination of simplicity, accuracy, and free-tier generosity has made it a default first tool for individuals and small teams starting prospecting programs. While it lacks the intent data, firmographic depth, and compliance infrastructure of enterprise B2B data platforms, Hunter.io's focused email finding capability and ease of use have sustained strong growth in the individual and SMB prospecting segment.

About
Kaspr is a B2B contact data platform that helps sales development representatives find phone numbers and email addresses of business prospects, with tight LinkedIn integration that allows data extraction directly from LinkedIn profiles. Founded in 2018 and headquartered in Paris, France, Kaspr was acquired by Cognism to strengthen the combined entity's European contact data coverage and distribution through complementary product channels. Kaspr targets SDR teams seeking fast, LinkedIn-native access to prospect contact data.\n\nKaspr's Chrome extension integrates directly into LinkedIn, allowing SDRs to reveal contact details for prospect profiles with a single click without leaving the LinkedIn interface. The platform's contact data covers mobile phone numbers and professional email addresses for European and international business contacts. Contacts can be pushed to CRM systems and sales engagement platforms directly from the extension, reducing manual data entry in the prospecting workflow.\n\nFollowing its acquisition by Cognism, Kaspr operates as a complementary product in the Cognism portfolio — with Kaspr serving individual SDRs and smaller teams seeking affordable LinkedIn-native prospecting tools, while Cognism's enterprise platform serves larger revenue teams with bulk data exports, intent signals, and GDPR compliance infrastructure. The acquisition strengthened Cognism's coverage of French and broader European prospect data while adding a LinkedIn-integrated product channel to its portfolio.
