Vida Ventures GP III, L.L.C.

Vida Ventures GP III, L.L.C. discloses dealings in 2 companies, chiefly LB Pharmaceuticals Inc and Vigil Neuroscience, Inc. We count 8 filings; the first trade dates from 11 January 2022 and the latest from 12 September 2025.

Purchases make up the whole of the open-market record (4 purchases, €25.0M). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2025: 2 purchases and no sales on the market.

Half of the purchases are above €2.1M and half below. Clusters matter here: 2 out of 4 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The latest filing, published on 16 September 2025, reports an open-market purchase of €4.3M in LB Pharmaceuticals Inc. The median gap between a trade and its publication by SEC (Form 4) is 4 days. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
