Fast applying still lands you in a pile.

Each swipe lands in a crowded queue.

Weeks later, you're still waiting.
Skip the pile. Land in the founder's inbox.
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.
BackdoorNothing goes out without your yes
You read every draft first, and nothing leaves your Gmail until you reply SEND.
BackdoorIt sounds like you, not a template
Each note says why you fit that startup, written from your own background, not a stock pitch.
BackdoorA founder reads it, not a filter
Your note goes to the founder's inbox, the person who can actually say yes to you.
Replies come in weeks, not months.

It can be, if you want to apply to a lot of roles quickly from your phone. If you'd rather send fewer, more personal notes to founders and approve each one, Backdoor is built for that.
If you want founders to read you, Backdoor. It matches you to startups that fit and writes 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. Keep applying where it helps, and let Backdoor reach founders at startups that fit you, often before the role is posted.
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.
