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.

Backdoor does the searching, writing and chasing. You stay in the loop and say yes.
A founder reads it, not a filter
Your note reaches the founder or hiring manager directly, with no application form in between.
