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.
