Joel Karacozoff

Joel Karacozoff currently leads Y Combinator Partnerships at Stripe, where he manages the strategic relationship and integration pipeline between the global financial infrastructure provider and the accelerator's portfolio of emerging companies. Before joining the fintech sector, he built his operational expertise as the founder of Balto Sports, a technology startup that participated in the Y Combinator Winter 2020 batch. In December 2020, Karacozoff guided Balto Sports through a corporate acquisition by Fubo, a publicly traded sports television and video streaming platform operating under the ticker symbol NYSE: FUBO.

His professional background combines direct entrepreneurial experience in building venture-backed companies with a current focus on scaling fintech infrastructure across the broader global startup ecosystem.
