Know the founder before you sign.

Alex Example is a made-up founder.

Why it works

“He cut off every woman in the design review, then repeated our idea as his own.”

Talked over or dismissed women×4Condescending to people×3

One meeting is easy to dismiss. Four women describing the same meeting is a pattern.

01

Look them up

Search any founder by name or company, before you join, invest or partner.

02

Read the strip

How they treat people, whether they keep their word, rated by people who worked with them.

03

Pay it forward

Worked with a founder? Review them anonymously so the next person walks in with eyes open.

How we keep it fair

Built so it can’t be used as a weapon.

  • Only members can read reviews. Nothing here appears on Google.
  • Reviews describe what the founder did. A moderator checks every one.
  • No phone numbers or personal addresses, ever.
  • Anyone can report a review. What doesn't hold up comes down.
  • Founders can reply to any review, once we confirm it's them.
  • Good experiences count too. Vouch for founders who did right by you.

Ex-employees would tell you. Now they can.
