What Happened: The Timeline
Founded by Dave Morin (ex-Facebook) as intimate social network with 150-friend limit
Path 2.0 launches; beautiful design wins Apple Design Award
15M registered users; fined $800K by FTC for uploading contacts without permission
Gained traction in Indonesia/Southeast Asia but US users abandoned the app
Shut down completely; briefly acquired by Kakao (Korean messaging company)
Root Causes
Key Lessons Learned
1. Artificial constraints can kill network effects
The 150-friend limit (based on Dunbar's number) made sharing intimate but prevented the viral loops that grow social networks. Each user was a dead-end for distribution.
2. Design excellence doesn't replace distribution
Path was widely considered one of the most beautifully designed mobile apps ever built, winning Apple awards. But users chose ugly-but-connected Facebook over beautiful-but-isolated Path.
3. Privacy violations destroy trust in privacy-first brands
Path's FTC fine for secretly uploading address books was especially damaging because the product positioned itself as the privacy-respecting alternative to Facebook.
