A digital advertising technology company, PubMatic builds a cloud platform that automates the buying and selling of online ad space for publishers — websites, apps, and video creators — handling the fast, automated auctions that place ads on pages. Founded in 2006 by brothers Rajeev and Amar Goel with two partners, the company got its name by blending "publisher" and "automatic," and early software was built in Pune, India. Co-founder Amar Goel has said his favorite first-year memory was simply printing out the wireframes for the early product — not yet serving real ads, but finally making the vision tangible.
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.
