# Start Founding

`POST /founding`

Capture the idea and open an interview in ``naming``.

Fail-fast gates only (Light tier, founding caps, the platform company cap).
**No moderation call**: moderation moved in-interview to the model's
``reject_founding`` tool, which also covers the mid-interview pivot an
idea-only gate never saw. **No credit gate either**: interviewing is free and
a founder can top up mid-flight; the credit floor applies to the INITIAL turn
at the very end, where it is a visible stall rather than a refusal.
