Hunter.io finds email addresses for companies that already exist. FirstMark Data finds email addresses for businesses that just launched - companies that Hunter.io has never crawled and cannot find yet.
Quick answer: Hunter.io and FirstMark Data both provide verified email addresses, but from completely different sources. Hunter.io crawls existing websites to find publicly listed email addresses. FirstMark Data processes business registration data to surface emails from businesses that launched in the last 30 days - businesses whose websites have not been crawled by Hunter.io yet. If you want to email new businesses before any competitor does, FirstMark Data has what Hunter.io cannot provide.

Hunter.io is a web crawler. It visits websites, finds email addresses listed publicly, and indexes them. This works well for established companies that have had time to build a web presence. But for new businesses, it creates a significant gap.
FirstMark Data bypasses all of this. We process business registration records directly, surfacing contact data from the registration itself rather than waiting for web crawlers to catch up.
