Fidelity Management & Research Company is an investment adviser within Fidelity Investments, managing portfolios for investment funds and other clients, including exposure to private companies.
Fidelity’s research-led technology investing examines both public and private businesses. Its AI framework covers the computing components and infrastructure needed to run models as well as companies applying the technology, connecting private-company analysis with the wider listed market.
FMR manages capital through investment products and client mandates. A financing attributed to the manager can therefore involve fund-managed capital, rather than a standalone accelerator or a standard programme with a fixed investment offer for founders.
