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!
The guys at SmartReach.io have created a pretty cool plugin for LinkedIn and Gmail. Find contact details while browsing LinkedIn, or directly within gmail as you are composing a new message.
We think the Gmail email finding feature is pretty cool, and definitely unique. If you use Gmail a lot, and outreach to many people on a case-by-case basis, we'd recommend it!
