Alex Robinson is the CEO and Co-founder of Juniper Square, a San Francisco-based private markets software platform serving 2,000+ GPs managing over $1 trillion in investor equity. Founded in 2014 after Robinson spent years at Microsoft and building GreenDoor (a PACE clean energy lending platform that collapsed when federal regulators abruptly ended the subsidy program), Juniper Square has grown into a $1.1 billion unicorn after a $130M Series D in June 2025. Robinson's singular focus: digitizing the paper-and-spreadsheet world of private equity partnerships and making private markets infrastructure as reliable as the public markets infrastructure that came before it.
