How to find a co-founder who actually stays

5 min read

Finding a co-founder is easy. Finding one who is still there a year later is the hard part.

The strongest partnerships share three things: honesty about what each person actually wants, a rhythm of communication that survives a bad week, and a shared definition of what "done" looks like.

Green flags to look for: they follow through on small promises before you make big ones together. They disagree with you early instead of going quiet. They ask what you need, not just what you can do.

Red flags: all talk and no shipping, disappearing for days, and a vision that shifts every time the market does. On Krooko you can see how someone communicates before you ever commit — start with a message, not a marriage.
