Blumberg Capital was founded in 1991 by David J. Blumberg, who brought a rare combination of operating experience - as one of Check Point Software's first four senior executives - and international investing credentials from T. Rowe Price, Apax Partners, and the Bronfman Family Office. That dual foundation shaped a genuinely hands-on early-stage investing model, leading Seed and Series A rounds in AI, big data, fintech, insurtech, and cybersecurity companies with $500,000 to $5 million checks, and serving as active board members from inception through exit. The firm has backed more than 160 active companies producing five unicorns and seven IPOs, including DoubleVerify's 2021 NYSE listing (a reported 98x return on Blumberg's 2008 investment), Nutanix, and Braze, and now manages more than $750 million with offices spanning San Francisco, Tel Aviv, Miami, and New York.
DoubleVerify's NYSE IPO under ticker DV in April 2021 at a valuation exceeding $3 billion - Blumberg's early 2008 investment delivered a reported 98x return, one of five unicorns and seven IPOs across the firm's portfolio
