MDB Capital

MDB Capital, founded in 1997 and based in the United States, operates an integrated venture-building and capital-markets platform focused on deep technology. The firm's stated approach, which it terms "Public Venture", involves curating and developing technology companies and supporting their launch into public markets - a model that combines elements of company building with public-market execution rather than relying on conventional private funding rounds alone.

The platform comprises three principal capabilities: a company-building and launch function for curated deep-technology ventures; investment-related services directed at technology inventors and entrepreneurs; and a brokerage business conducted through Public Ventures, LLC, a broker-dealer registered with the U.S. Securities and Exchange Commission. The broker-dealer registration is a distinguishing structural feature, permitting the firm to handle securities activity in-house as companies progress toward public listing.

Technology domains cited by the firm span deep technology, public venture capital, broker-dealer services, company building and capital markets. Its stated mission emphasises backing visionary technology, inventors and entrepreneurs, and it engages three audiences: founders submitting technology ideas, investors assessing public venture opportunities, and a community of members. Operating continuously since 1997, the firm occupies a niche at the intersection of venture formation and the public equities market.
