How to pitch a VC firm in Boston
Open the firm's profile first: its stage focus, the sectors it actually funds and the size of round it usually joins. Then write to the partner who covers your space, with the traction and the ask in the first three lines. A fund that has done many deals in your sector this year is a warmer lead than a famous name that has not.

Frequently Asked Questions
How many VC firms are there in Boston?
The Round Funded catalog lists 105 active venture capital firms in Boston, after excluding banks, lenders, wealth managers, insurers and real-estate vehicles. This page shows the top 50 by investments on record; the count updates as the catalog is refreshed.
How is this list ranked?
By the number of investments on record for each firm, then by how complete its profile is. It is a catalog ranking, not an editorial one: a fund with many recorded deals sits above a famous name with few.
How do I get in touch with a VC firm in Boston?
Every firm on this page links to its profile with stage and sector focus. Sign up to see the partner contact behind each firm and send your pitch from your own Gmail, with replies tracked on the Round Funded pipeline.
Are these firms actively investing?
The catalog is built from funds with recent investment activity and is re-checked continuously; each profile shows the investments on record. Read the firm's stage and sector focus before you write, since an active fund in the wrong sector is still a no.
What is Round Funded?
