Harj Taggar is a Managing Partner at Y Combinator and serial founder who went from Oxford law to Silicon Valley startup culture. He co-founded Auctomatic with the Collison brothers (Patrick and John, later of Stripe fame) in 2007, sold it for $5M in under a year, then became YC's first non-founder partner in 2010. He co-founded Initialized Capital with Garry Tan and Alexis Ohanian, co-founded technical hiring platform Triplebyte in 2015 (acquired by Karat in 2023), and returned to YC in 2020 as a Group Partner before becoming Managing Partner. He has advised over 1,000 companies across 17 YC batches and worked with more than 20 unicorns including Coinbase, Instacart, and Gusto.
John Collison is the President and co-founder of Stripe, the Irish-American payments giant he built with his brother Patrick from their rural Tipperary roots into a $159 billion fintech colossus processing $1.9 trillion annually. He sold his first company at 17, dropped out of Harvard at 19, and by 26 was the world's youngest self-made billionaire - all while maintaining the understated disposition of someone who grew up in a village of a few hundred people on Lough Derg.
