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 Series B round in Cybersecurity?

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.
