MailsHunt is a relatively small, new tool that helps you to find anyone's email address and connect with the people that matter for your business.
It's generally nice to support new, smaller tools and we like how their Domain Search lists all the email addresses of people who are working in a particular company.
Seamless.AI is a B2B database with a twist. Every time someone performs a search, their AI engine researches and verifies emails and direct dials in real-time, which keeps the data fresh. They also provide an email finder Chrome extension.
They have a pretty unique approach, and while judging by reviews the results are mixed across different niches, it's definitely worth a shot!
