Wellington Management is an investment manager with a private-investing platform spanning venture capital, growth and private debt, informed by its public-market research.

Its equity strategies include early-stage venture, private biotech, climate growth and late-stage growth. These teams address different development needs, from scientific breakthroughs and medical demand to scaling industrial systems and preparing for public markets.

A Value Creation Team connects portfolio companies with Wellington’s public- and private-market specialists from seed through IPO. The wider platform also provides growth lending, giving some businesses a debt-financing route alongside equity capital.
