Posterous

Posterous is the blogging startup founded by Garry Tan and Sachin Agarwal in Garry Tan on Returning to Y Combinator. The product began as a side project for posting to a blog by email, then grew quickly because the early iPhone made photo capture easy while dedicated mobile photo-sharing apps were still immature.

The source uses Posterous as a Startup Timing Windows case. The same timing that created the opportunity also exposed the company when Instagram focused tightly on photo upload flow and network growth. Tan says that from inside the company, founders often cannot clearly see why growth is happening or why it stops.

Posterous also becomes a Co-Founder Conflict case. Tan describes himself as conflict-averse and says unaddressed disagreement over the company’s direction harmed his sleep, appetite, functioning, and health. The lesson is not only that Posterous lost a product race, but that founder communication and conflict management can determine whether the team can respond to a product shift.

Founder Mode: Garry Tan, President & CEO, Y Combinator revisits Posterous from the leadership side. Tan says the company sold for $20 million and changed his life, but fell short of what it could have been because he stayed too much in maker mode, gave hires low-risk work, and did not fully delegate, hire, manage, and lead.
