The 50 most recent seed rounds in biotechnology span April through November 2025 across at least 16 countries, with the United States accounting for roughly half the entries. Chicago alone contributed five companies — Clever Carnivore, Madison Scientific, 32 Biosciences, OrisDX, and Stately Bio — making it the most concentrated single city in this dataset. Round sizes range from QRL Bioscience's $340K (Ahmedabad) to Integra Therapeutics' $13M (Barcelona), with Stately Bio ($12M), Dash Bio ($11M), and Araceli Biosciences ($11M) rounding out the top tier. Ten of the 50 rounds are undisclosed, including four Chinese entries — BayOmics (Shenzhen), Yuantian Bio (Tianjin), Jingcui Bio (Zhongshan), and Zhonghe Gene (Dongli).
The UK is the most active non-US country, with six companies across four cities: Newcastle Upon Tyne (InvenireX, GlycanAge), London (BoobyBiome, Samphire Neuroscience), Nottingham (Forge Genetics), and Cambridge (OutSee). Switzerland (arcoris bio, Hemostod, SEITO Biologics) and Spain (Integra Therapeutics, Bioinspired Materials) each contribute multiple entries, reflecting meaningful European seed activity alongside the dominant US pipeline.

Frequently asked
What are the largest disclosed seed rounds in this group?
Integra Therapeutics (Barcelona) tops the list at $13M, closed in September 2025. Stately Bio (Chicago) raised $12M in May 2025, and both Dash Bio (Boston) and Araceli Biosciences (Tigard, Oregon) closed $11M rounds in July and April 2025, respectively. arcoris bio (Schlieren, Switzerland) and Immuto Scientific (Madison, Wisconsin) each raised $8M.
Which city has the highest concentration of seed-stage biotech companies in this dataset?
Chicago appears five times — Clever Carnivore, Madison Scientific, 32 Biosciences, OrisDX, and Stately Bio all closed seed rounds there within this window, more than any other single city. San Francisco (Hermes Biosciences, Mana.bio) and London (BoobyBiome, Samphire Neuroscience) each appear twice.
How does the UK compare to other non-US geographies in biotech seed activity?
The UK contributes six companies — the highest count of any non-US country — spread across Newcastle Upon Tyne (InvenireX, GlycanAge), London (BoobyBiome, Samphire Neuroscience), Nottingham (Forge Genetics), and Cambridge (OutSee). China follows with four entries (BayOmics, Yuantian Bio, Jingcui Bio, Zhonghe Gene), all with undisclosed amounts. Switzerland accounts for three (arcoris bio, Hemostod, SEITO Biologics).
What share of rounds have undisclosed amounts, and where are they concentrated?
Ten of the 50 rounds list undisclosed amounts, roughly 20% of the dataset. Four of those ten are Chinese companies — BayOmics, Yuantian Bio, Jingcui Bio, and Zhonghe Gene — while the remaining six are spread across the US, Canada, and Denmark.
What does the distribution of round sizes look like across the 40 disclosed amounts?
Among the 40 rounds with disclosed figures, the median sits at $4M. The majority cluster between $2M and $8M, though the range is wide: QRL Bioscience (Ahmedabad) raised $340K at the low end while Integra Therapeutics raised $13M at the high end. Seven rounds came in at $5M exactly, making it the single most common disclosed amount.
Are there any notable timing patterns in when these rounds closed?
The most recent entries from October and November 2025 are dominated by US companies (Hermes Biosciences, LambdaVision, Clever Carnivore, Rarity PBC) and UK (InvenireX). The May–July 2025 window shows broader geographic spread, including Stately Bio, Araceli Biosciences, Antler Bio (Dublin), Pictor (Auckland), and Preventix (Philippines).
