What the numbers say

The two largest deals are 79% of the month's capital, so the total describes a handful of companies rather than the market.

1 of 5 rounds were pre-seed or seed, and together they drew 11% of the capital. The formation end is busy and cheap.

1 of 5 rounds came out of an institution (ETH Zurich 1), which is the structural feature of this market rather than a feature of the month.

18 distinct investors were named across 4 rounds, none of them twice. No fund built a visible position this month.

1 transaction is announced rather than closed and its figure is excluded from every total above: Prem (USD 100M, raising, expected to close in Q3). A ceiling quoted gross, before redemptions and subject to approval, is not capital raised.

2 of 4 closed rounds have been checked against a primary source, covering CHF 26M of the CHF 33M, 79%. The rest is as reported. Every error found in this database so far was a figure or a label that a primary source contradicted, so that share is the weight this page can carry.

The database records what the press carried, so undisclosed rounds and quiet extensions do not reach it, and 4 of 5 rounds name their investors. This is reported activity, not a market census, and one month is too short to read as a trend.
