Boston has 834 investors in the Robynhood database, counting Cambridge. It is the only city on this list where life sciences is the defining story: healthtech at 175 plus biotech at 76 gives 251 investors in health and bio, comfortably ahead of anything else.

The life sciences capital of the database

Boston's 76 biotech investors are the highest count anywhere relative to city size. Combined with 175 in healthtech, roughly three in ten Boston investors with a stated focus are in health or bio.

The universities explain most of it. A large share of these investors either research, teach, or built companies out of the labs around Kendall Square, and they can assess a scientific claim in a way generalist investors cannot.

AI/ML at 166 is strong too, and increasingly overlaps with the bio group rather than competing with it.

Small, expert, and quick to say no

460 of 834 have a verified email — 55%.

Boston is a technical audience. Vague scientific claims are caught immediately, and a deck that would pass elsewhere gets picked apart here. That is a feature if your science is real.
