Today we catch up with Harj Taggar, who knows as much about startups as anyone of his generation. YC funded two of his startups, Auctomatic in 2007 and Triplebyte in 2015. In between them he was the first partner we hired besides the founders, and now he's a YC partner again. Among other things he happened to have a front row seat for the Damore controversy in 2017, and is one of the few people who know just how extreme things got in those days.

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.

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.

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.
