Company Signal lists funders so founders can find them. We are not a broker or a financial adviser: we do not recommend funders, pass pitches on or take any fee from them, and nothing here is an offer of finance. Each entry comes from the funder's own public pages, last checked 1 Oct 2026; amounts, terms and rates change, so check them with the funder before you apply.
