Christopher Vanderhook: trading record in brief
Christopher Vanderhook (chief executive) discloses dealings in Viant Technology Inc. to SEC (Form 4). The record holds 55 filings, for trades running from 10 February 2021 to 10 September 2026.
Every open-market trade on record is a sale: 23 sales worth €12.4M. The rest of the record consists of 4 share grants and 10 option exercises. Since January 2026: no purchases and 15 sales on the market.
Most recently, on 14 September 2026, the filings show a transaction worth €95k in Viant Technology Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
