Invite loops for solo founders
An invite loop works when completing the job naturally requires another person.
The mechanism
User reaches value → product prompts a contextual invite → invited user experiences value → cycle repeats.
Solo-founder translation
Ship one invite prompt after the first successful outcome. Measure invites sent and activated invitees for 14 days.
When not to copy
If your product is single-player, force-fitting invites creates spam, not growth.
