Recently Funded Biotechnology Startups in Boston

FundedIQ tracks 110 funded Biotechnology startups in Boston. This page lists the 100 most recently funded of them, ordered by the date of their latest round, and the full set is available on a FundedIQ plan.

Biotechnology startups in Boston tracked by FundedIQ have raised $2.7B in disclosed capital across 55 funding rounds over the last 24 months, including 34 rounds in the last 12 months. 47 of those 55 rounds disclosed an amount; undisclosed rounds are excluded from the capital total.

The median disclosed round over the last 24 months is $41M, and the middle half of rounds fall between $12M and $78M. Round sizes vary widely by stage, so the seed and later-stage bands sit well either side of that figure.

Series A is the most common labelled stage, with 15 rounds in the last 24 months, ahead of Seed (9) and Series B (5). A further 22 rounds were announced without a stage label and are not counted here.

The dataset is refreshed weekly. New rounds are normalised and de-duplicated before they are published, and the most recent round currently on record for funded Biotechnology startups in Boston is dated Sep 2026. Counts and totals on this page are recomputed on every refresh.
