# whowhy
> Double opt-in intros for hiring. The candidate says yes. You say yes. Then you meet. For founders and hiring managers at fast-growing startups. No recruiters allowed.

How it works:
- you: send the role (link or a few words)
- whowhy: sample in 2 minutes
- you: yes or no per person
- whowhy: writes to your yeses, then to people like them
- candidate: yes
- meeting

## pricing
- deposit: $100 (covers 2 meetings)
- per meeting: $50
- no subscription

## use it from Claude, Codex or Grok (MCP)
Run whowhy from Claude, Codex or Grok: start a role, see who was found and why, and pick whom to meet. It changes something only when you ask (creates a role, saves your yes and no, edits the email, moves someone on your pipeline); it asks you before every change. Sign in with your work email; the first sign-in creates your account, no card needed to start. Add ?read_only=true to the URL and every tool that changes something disappears.

## for candidates
whowhy writes to you when a company said yes to your profile, or when you look like a person it said yes to. One email, from who@whowhy.io (sender name: whowhy): the role, the pay, the company, the hiring manager and why. Reply yes, and if the founder wants to talk too, whowhy introduces you both by email: a meeting with the founder, never a recruiter. No recruiters allowed. Reply no and say why, and the next one will fit better. Reply stop, and whowhy never writes again. There is no login and no account for you: all of it happens by email. You never pay.
