How to read these figures

They come from announced rounds. Large rounds are almost always announced and many small ones never are, so the true typical round is probably a little smaller than shown, most of all at pre-seed and seed. Every round behind them is in the record with its source. How we read rounds.

Q&A

How big is a typical seed round in Biotech?

The median is $7.3M, from 60 seed rounds announced in Biotech in the last twelve months. Half of them raised between $3.3M and $13M; one in ten raised more than $22M.

Which rounds are counted?

Rounds announced in the last twelve months with a stated amount and stage, each read from a named article or filing. A page is only published where at least 30 rounds stand behind it.

Are these figures biased?

Towards larger rounds, yes. Big rounds are announced; many small ones never are. So the true typical round is probably a little smaller than the figure here, especially at pre-seed and seed.

How often does it change?

The figures are recounted from the record every night, as new rounds are read.
