Posterous Cofounder Garry Tan Steps Down, Heads To Y Combinator

Garry Tan, one of the cofounders of easy-to-use blogging service Posterous, is moving on from the company. Tan will be leaving to take a position at Y Combinator, where he will serve as a designer in residence. Posterous doesn’t put much weight on titles, but Tan had a hand in the site’s engineering, design, and product development.

Posterous isn’t taking off as quickly as its competitor Tumblr, but it has a solid audience and has recently released a neat Groups feature. Tan didn’t elaborate much on his reasons for leaving, but says that it boils down to wanting to work with smaller teams, which he’ll be able to do at Y Combinator (Posterous is now at around 13 employees). He also added that Posterous is going “gangbusters” and that he expects 2011 to be “really phenomenal”.

Posterous has raised over $5 million, including Y Combinator funding and a Series A round in March 2010.

Here’s Tan’s post announcing the news on his Posterous blog:

Just as Posterous has prospered, grown and changed, so to is it time for me to evolve my role. Effective today, I’m ending my day-to-day development with Posterous and moving into an advisory role. Though my day-to-day may change, my faith in the team and the product is unchanged and unwavering. Posterous is in good hands and on the right track to fulfilling its potential. I am proud of what we’ve built together and look forward to the future with anticipation to see where the team and you, the users, take this very special community.

My greatest passions lie with the early stage of building world-changing consumer products. To that end, I’ve decided to join the team at Y Combinator as a designer-in-residence and help the dozens of top pre-seed startups in the newest Winter 2011 batch reach their potential through excellent user experience.

I am greatly thankful to our team, investors and most of all our users for all the amazing work and adventures. Thanks for all of your support.
