Brian Hirsch

Brian Hirsch is a declared insider at 2 companies (board member); the most frequent names are ACV Auctions Inc. and Katapult Holdings, Inc. Between 9 June 2021 and 27 May 2026, the trades on record add up to 32 filings.

The open-market side counts 5 purchases for €1.0M alongside 9 sales for €16.2M. Sales outweigh purchases by €15.1M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 3 share grants and 2 option exercises.

Half of the purchases are above €163k and half below. Clusters matter here: 4 out of 5 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The newest entry dates from 29 May 2026: a share grant, in ACV Auctions Inc. The clock since the last published purchase (14 November 2025) now reads 338 days. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
