Before joining Industry Ventures, Jonathan Roosevelt was an early employee and VP of Sales at SoFi, co-founded companies including Epesi Technologies with James Park (who later co-founded Fitbit), was an early angel investor in Fitbit itself, and built a health-focused business with more than 200 employees. His investing approach centers on getting access to competitive venture rounds through SPVs, and when evaluating mid-stage deals he pays close attention to the track record of the earlier-stage investors involved and talks directly to customers rather than relying mainly on market comparisons.
