I’m delighted to announce that Ali Rowghani is joining YC as a part-time partner.  He will mostly focus on helping our alumni that are a few years out of YC scale their companies, but I’m sure the current batch will enjoy getting to know him as well.

Though we’ve traditionally focused on helping very early-stage companies, our successful companies have asked for help on topics like scaling operations, managing hypergrowth, building out management teams, etc.

Ali is a perfect fit for helping YC companies with these scaling questions.  Ali was the CFO at Pixar, where he spent 9 years working closely with Ed Catmull and Steve Jobs.  In 2010, he joined Twitter as its first CFO, at a time when Twitter had about 100 employees, 20 million users, and virtually no revenue.  In late 2012, he became Twitter’s COO and took on many additional responsibilities within the company.

Welcome, Ali!
