Why Open Select exists

Most recruiters optimize for speed. I optimize for the hire you're still happy with two years later.

I've recruited engineers for startups since 2011. By the end of our first call I usually already have people in mind, because I've spent years talking to engineers long before your role existed.

  • 01You deal with me. No account managers. No handoffs.
  • 02Straight answers. On candidates, comp and your process, even when it's not what you want to hear.
  • 03I build with AI every day. When an engineer explains their work, I can follow it.

Let's build your team.

Pick a time that suits you. A 15-minute call, a search strategy memo, and a decision in 48 hours.
