About Marshall Porter

Kevin Ryan is unusual among VCs in that he personally founded or co-founded many cornerstone NYC tech companies like DoubleClick, Business Insider, and MongoDB, giving him a founder-operator perspective rather than a purely investor background. Unlike most VCs who select into existing teams, Ryan systematically originates ideas inside AlleyCorp and then recruits outside CEOs whose specific skills match what each company needs, treating CEO selection as the core value-creation lever.
