MDB was founded in 1997 with the purpose of backing visionary technology, inventors, and technology entrepreneurs via a new form of public venture capital that finances pre-revenue, early-stage companies through early public offerings, primarily listed on NASDAQ. After successfully launching 16 companies under this public venture model, MDB believes the natural next step is to become a public entity and attract investors who share its vision to continue to launch new platform technologies into the public markets. MDB currently has two wholly owned subsidiaries, Public Ventures, LLC and Patentvest, Inc., and a majority-owned company that is also a partner company, Invizyne Technologies, Inc.
