Every round, newest first

How we built this list

We started this list while fact-checking our guides to 27 venture firms in October 2026, and we update it every month. A round is here if one of those firms led or co-led it, it was a seed or pre-seed round, it was announced between November 2025 and October 2026, and the firm's own site or a named publication reported it. It is not a census of all seed rounds: it covers only these firms and only rounds we could source. Social posts and videos are never the only source for a row.

Sizes are whole rounds, not the lead's own check. Euro rounds stay in euros and are left out of the median, as are rounds reported only as a range or combined with a Series A. Where a firm co-led, every named co-lead is listed. The full list is also available as JSON. For how each firm invests and how to reach it, see the 27-firm comparison.
