Active technology investors in Massachusetts — 2026

543 investors backed the 39 most recent of 137 technology offerings by companies in Massachusetts in the last 12 months, per SEC Form D.

Funds file one too when they raise, which is how we list the venture and private equity funds based in Massachusetts. Figures come straight from SEC EDGAR and refresh daily.

Offerings are matched on the Form D industry group (Computers, Telecommunications, Other Technology) and the company’s business address, one offering per company, funds excluded. Each filing reports how many investors have already invested, not who they are, so an investor in two offerings counts twice. Run the same search on sec.gov.

Funds with “Tech”, “Technology”, “Technologies”, “Software” in their name

Form D doesn’t say what a fund invests in, so this is a keyword match on the fund’s name, not a stated technology focus. Venture capital and private equity funds in Massachusetts that filed in the last 12 months.
