John Bowman

John Bowman is a co-founder and Chief Business Officer of Maybern, the New York fintech building fund management software for private markets. After more than two decades inside Goldman Sachs' Merchant Banking Division and a stint as CFO of Periphas Capital, he switched sides: instead of suffering through spreadsheet-driven fund accounting, he helped build the tool that replaces it. Maybern raised a $50M Series B led by Battery Ventures in November 2025.
