Bio

Jack is the co-founder of RowFlow. He spent 8 years scaling marketplaces at Uber, Shef (YC19), and Faire (YC17), where he built 0-to-1 operational systems, standardized messy onboarding flows, and most recently led human-in-the-loop ML programs. He holds a degree in Statistics and Operations from Wharton, where he graduated in 2017.
