Questions, answered.

Anyone aiming for a pre-seed to Series C startup, where one good email to a founder can become an interview. If you want to mass-apply to big companies, it isn't for you.

Job boards put you in a pile. Backdoor writes straight to the founder, often before a role is posted, about why you fit them.

No. Every new email waits for your SEND. Follow-ups only continue threads you approved, and you can cancel them anytime.

Backdoor connects to your Gmail so it can send the emails you approve and tell you when a founder replies. Connecting it is optional, and the privacy policy has the details.

Yes, when the email is about why you fit them. 9 in 10 people who heard back through Backdoor got their first founder reply within two weeks, and more than half of those who gave it three weeks heard back. Founders at early startups read their own inbox.

Follow-ups stop, you get a text right away, and the full reply lands in your inbox.

Chat, profile research and your resume are free. Outreach starts with a first week for $1, and you can cancel anytime.

No, nothing can. It handles the research, emails and follow-ups. The interview is still you.

Free to start ยท No forms ยท No app

Your next role is one text away.

Say hi and share your LinkedIn. Backdoor takes it from there.
