In today’s episode, we chat with all three of the Gusto founders: Josh Reeves, Eddie Kim, and Tomer London. Gusto is a payroll and employee benefits company that YC funded in 2012. The striking thing about Josh, Eddie, and Tomer is their level of commitment: to their customers, their employees, and one another. It's rare to see a startup with 3 founders still being run by all 3 founders 12 years in, but these guys are special.

In Part 2 of our conversation with legendary investor Ron Conway, we chat about how he made one of the most prescient decisions in the history of startup investing when he decided in the early 1990s to focus exclusively on investing in internet startups. It's like being a fly on the wall at the beginning of the internet boom as he takes us through shadowing Sequoia founder Don Valentine and "living" in Netscape's office as it took off.

In this episode, we speak with Surbhi Sarna, founder of nVision Medical, a pioneering company in women's health diagnostics.

Now a Partner at Y Combinator, Surbhi discusses her transition from founder to mentor, offering insights into the challenges of healthcare innovation. Her book, Without a Doubt, was released in 2022.

We’re back with Tyler Shultz for the second part of his story: the whistleblowing. He’d resigned after noticing potential fraud within Theranos. After he spoke on background to the Wall Street Journal, Theranos retaliated with a series of legal threats, intimidation, and surveillance -- all designed to silence him. Tyler tells us about the nightmare leading up to when the news story broke, and the world found out about Theranos. (Learn more about Tyler at tyler-shultz.com.)

Tyler Shultz went to work at Theranos right out of Stanford and soon noticed that things weren't as they seemed. Lots of other employees knew there was something fishy going on, but Tyler was one of a tiny handful able to resist the mesmerizing and intimidating Elizabeth Holmes and speak out about the fraud that was putting patients at risk. This podcast is a lesson for anyone who wants learn what it takes to speak out against misdeeds by powerful people. (Learn more about Tyler at tyler-shultz.com.)

Today we catch up with Dan Siroker, co-founder of Limitless, which trains a personal AI to remember things for you. Y Combinator funded his previous company, Optimizely, in 2010, and it was acquired a decade later. But before he started Optimizely he ran the new media group within the Obama campaign, which achieved stunning results through A/B testing. In fact Optimizely was the software he wished he'd had then.

In today's episode we catch up with Eddy Lu, co-founder and CEO of GOAT, the fashion marketplace. GOAT represents one of the most epic pivots in Y Combinator history: they started out organizing group dinners. Founders are often told they should be "scrappy". Eddy and his cofounder Daishin are scrappiness personified, and that's what enabled them to bounce from idea to idea and end up on top.

David Rusenko was a college student when he applied, at the last minute, to Y Combinator in 2006. His startup, Weebly, made a web site builder. At one point they came within days of running out of money, but they survived to be acquired by Square in 2018 for $365 million. Now David runs a fund, Leap Forward Ventures, focused on climate change. He has spent his whole career in startups, and has seen close to everything that can happen.
