## Questions

### How does MDB Capital Group structure its investments differently from traditional venture capital?

MDB Capital states it pursues a model that brings deep technology companies to the public markets earlier than conventional venture firms. It prioritizes public liquidity and structures deals so that founders, co-founders, and university partners retain higher ownership stakes relative to traditional venture funding rounds. The firm describes its approach as more democratic and liquid, aligning the incentives of inventors, investors, and employees without imposing the decade-long lockups typical of closed-end venture funds.

### What kinds of companies does MDB Capital target for its pipeline?

MDB focuses on deep technology “Big Ideas” that originate with inventors, universities, and co-founders. Its stated investment range spans the earliest stages — seed, startup, and pre-IPO — with an emphasis on scientific discoveries and technologies that can support high-value job creation and economic growth. The firm has not published a public portfolio list detailing specific companies or sector sub-verticals beyond the broad deep-tech category.

### Does MDB Capital disclose its assets under management or fund structure?

MDB Capital does not publicly report assets under management or total capital deployed. It likewise does not publish details on whether it raises capital through a registered investment vehicle, a single-family commitment, or a network of individual participants. The firm’s website references an “MDB Investor Community” that participates in its deals, but the legal and regulatory framework governing that community has not been made public.

### Who leads investment decisions at MDB Capital?

MDB Capital has not identified named principals, portfolio managers, or investment-committee members on its current website or in the materials reviewed. The firm describes a collaborative architecture that rewards long-term employees, but the individuals responsible for deal sourcing, underwriting, and governance remain publicly undisclosed.
