Matthew Jacobson

Matthew Jacobson, listed as board member, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Datadog, Inc., Gitlab Inc. and Braze, Inc. We count 82 filings; the first trade dates from 13 May 2020 and the latest from 14 August 2026.

In open-market terms, that means 15 purchases worth €40.8M on one side and 33 sales worth €99.0M on the other. Taken together, the sales exceed the purchases by €58.2M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Since January 2026: no purchases and 6 sales on the market.

The median purchase comes to €579k. Clusters matter here: 11 out of 15 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. Looking at 11 purchases old enough to measure, the stock rose over the following 90 days in 27% of cases; the median change was -4.5%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 17 August 2026, reports an open-market sale of €694k in Datadog, Inc. The most recent open-market purchase was published on 7 December 2022, 1,414 days ago. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
