Ouster, Inc.
A maker of digital lidar sensors and perception software that let robots, self-driving vehicles, and smart infrastructure "see" and map their surroundings in 3D. Founded in 2015 by two Stanford classmates, Angus Pacala and Mark Frichtl, the San Francisco company merged with longtime rival Velodyne in 2023 and kept the Ouster name. The name is a fun quirk: "ouster" is the English word for ejecting someone from a position — fitting for a company that set out to shake up the lidar market.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -1.40M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
