Fidelity Management and Research Company

Fidelity sources through a combination of its 140-person equity-research department, existing public-market relationships with companies that later stay private longer, and the direct network of its venture-capital arm. The firm's size allows it to receive allocations that pure-play venture funds are too small to serve, particularly in late-stage raises above $500 million. Its public-market credibility means companies view a Fidelity ledger position as a signal ahead of an IPO.

Abigail Johnson holds approximately 24% of Fidelity's voting shares, with the Johnson family collectively controlling 49% — meaning no major corporate action can pass without family consent. Day-to-day investment decisions are delegated to professional portfolio managers and research analysts. The family's influence is most visible in capital-allocation strategy and succession planning rather than individual stock-picking.
