Announcing Season 3 of The Social Radars!

Today we chat with Adora Cheung, Co-founder of Homejoy (YC summer 2010) and now InstaLab, an at-home blood testing service that helps you optimize your health by measuring over 60 biomarkers. Our conversation is wide-ranging: from how to clean homes efficiently to how she helped defeat Trump in 2020 by getting hundreds of thousands of votes in swing states.

Today we have another insider episode: we're talking to Trevor Blackwell, who was my cofounder at Y Combinator. But that's not all he's done. He was also the founder of Anybots, where he created the first dynamically balancing biped robot, and also worked on Viaweb with Paul Graham and Robert Morris.

Today we're talking with Parker Conrad, who founded two startups that went on to become unicorns: Zenefits in 2013, and Rippling in 2016. Parker’s story is one the more dramatic ones you’ll hear on this podcast. In fact this episode is two stories: his misadventures at Zenefits, and the ambitious ideas he has implemented at Rippling.

Today we talk with Emmett Shear, who was in the very first YC batch in 2005 with a startup called Kiko. But you know him better as the co-founder of Twitch, which YC funded in 2007. Learn how Twitch grew from one guy walking around with a camera on his head to one of the biggest communities on the internet. It's a crazy story even by startup standards. Enjoy!

In this episode we catch up with Patrick and John Collison, two brothers from Ireland who founded Stripe in 2009. Since then we've watched Stripe grow from a two-man show to one of the great powers of the tech world

Today we're talking with Bill Clerico, co-founder of WePay which Y Combinator funded in 2009. WePay was one of the first of what are now called "FinTech" startups. In 2017, J.P. Morgan acquired WePay for $400M. Listen in to the adventures of an early fintech pioneer.

Today we're talking with Dimitri Dadiomov of Modern Treasury, a startup Y Combinator funded in 2018. Dimitri works in a very important world whose existence is hidden from most people: the movement of money into and out of companies. Listen in as we follow the money!

Today we're talking with Brian Armstrong of Coinbase, a startup YC funded in 2012 and is now a publicly traded company. Coinbase is truly in the middle of the exciting new world of cryptocurrency. It's particularly interesting to explore this world with Brian, who was unusually candid, even for Silicon Valley.

In today's episode, we're talking once again with Brian Chesky, co-founder and CEO of Airbnb. YC funded Airbnb in 2009, when the company was at death's door. During YC we watched the founders work frantically to get growth started and turn Airbnb into the rocketship that it is today. Today we pick up where we left off in Brian's incredible story of startup survival.
