Hunter.io finds the email address when you know who to write to. Backdoor finds the startup and the founder too, then drafts the note and follows up.

Same founder. None of the legwork.
Founders at early startups often read their own email. A short note about why you fit them stands out there in a way a form application rarely does.
A founder's inbox, the week a role goes up.
One short note, about why you fit. Then a reply.
Hey, this is great timing. We're about to open this role.
Free for a quick call Tuesday?
Here's what it feels like instead.
Backdoor does the searching, writing and chasing. You stay in the loop and say yes.

Questions, answered.
It's a quick way to find a founder's email once you know who you want. You still find the startups, write the note and follow up yourself, which Backdoor does for you.
Backdoor. It writes to each founder about why you fit, and more than half the people who gave Backdoor three weeks heard back from a founder, and 4 in 10 got to an interview or next round.
Yes. Use it for founders you already have in mind, and let Backdoor bring you startups you haven't found.
No. Every note waits in your chat until you reply SEND, and then it goes out from your own Gmail. After that, follow-ups go out on their own in the same thread.
