In this episode we walk down memory lane with Steve Huffman, co-founder and CEO of Reddit, who was in Y Combinator's very first batch of startups in 2005.

Hear about Reddit's eventful early years and how they affected what it eventually became.

Today we're talking with the fabulous Tracy Young, one of the most successful female startup founders so far. Y Combinator funded her company, PlanGrid in the winter of 2012. PlanGrid revolutionized the construction industry by getting blueprints off paper and onto tablets. You’ll hear about how they found their idea, how they lost a cofounder to cancer in the first few weeks of YC, how they sold the company for almost a billion dollars in 2018, and how she’s now gone on to start a new startup called TigerEye, with her husband and PlanGrid cofounder, Ralph Gootee.

In this episode we’re talking to Garry Tan, the president & CEO of Y Combinator. We go full circle with Garry as we chat about his path from turning down a job with Peter Thiel, to founding a YC-backed company in 2008, then starting his own multi-billion dollar fund in 2011, and finally returning to run Y Combinator in 2023. Garry knows about programming, design, running startups, and investing in them, so there are lessons and stories for everyone in this episode.

Back in 2009, YC funded his startup, Bump Technologies, which had a cool technology where you transferred your contact info from one person to another by literally bumping phones. He’ll share Bump’s ups and downs as they went from business school side hustle to hot new iOS app. He’ll talk about getting acquired by Google and ultimately transforming Bump into the wildly popular Google Photos. David recently came back to Y Combinator as a visiting group partner.

In the premiere episode, Jessica & Carolynn sit down with Paul Buchheit. Paul created Gmail in 2004 while he was employee #23 at Google. They do a deep dive into the history of Gmail, including the fact that it might never have launched if it weren’t for a leak to the New York Times. After Google, PB went on to found a startup called FriendFeed, which was a social media aggregator, and where the first “like” button was created. It was acquired by Facebook in 2009. After that, he joined Y Combinator as a partner and also became one of the most successful angel investors in Silicon Valley.
