I am an entrepreneur and investor, currently part-time at YCombinator helping early stage entrepreneurs. Prior to YC, I was Director of Product Management at Facebook where I led the Local product team.
I have also worked on Search and Ads at Google, started and sold a few companies, and invested in startups including Optimizely, Boom, Color, Cruise, Instawork, CaseText, and many more.
Most of my posts are based on email threads and conversations with entrepreneurs. If I end up sending the same email twice or have the same conversation twice, I turn it in to a blog post to save time in the future.
