Backdoor
Our pick: Backdoor
Anyone targeting pre-seed to Series C startups who wants to reach the founder first.
Backdoor picks startups that fit you every morning from funding, launch and hiring news, often before a role is posted. It finds the founder's email, drafts a short note, and sends it from your Gmail after you reply SEND. 9 in 10 people who heard back got their first founder reply within two weeks.
- Finds startups from fresh funding and launch news, before the job board rush
- Follows up 3 times in the same thread and stops when someone replies
- Works in WhatsApp or iMessage with no app to install
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.

How we picked.
We ranked tools by how directly they reach founders and hiring managers at early-stage startups, what reply evidence exists, price in $ and ₹, whether you approve what goes out, and public reviews. Backdoor ranks itself first because it is built for this exact job: it finds startups that fit you and emails their founders from your Gmail. If you want to browse and apply to posted startup roles, Wellfound and YC Work at a Startup are the right places. If you are a senior builder who wants warm intros only, Standout is worth a look first.
Questions, answered.
