PubMatic, Inc.

PubMatic, Inc. (NASDAQ: PUBM) is an independent sell-side advertising platform founded in 2006 by brothers Rajeev and Amar Goel with co-founders Anand Das and Mukul Kumar. Headquartered in Redwood City, California, the company IPO’d on the NASDAQ Global Market on December 9, 2020 at $20.00 per share. Rajeev Goel has served as CEO since inception. The business sits squarely in the same independent-SSP cohort as Magnite, with a parallel CTV-as-share-of-revenue trajectory and overlapping membership at the two governance fronts where the SSP layer is being rewritten in 2026: the IAB Tech Lab Programmatic Governance Council and the Amazon Dynamic Traffic Engine open-source extension.

The May 7, 2026 print is the next material read. PubMatic pre-announced Q1 2026 results above guidance on April 22 — revenue of approximately $62.4M against a $58.0M–$60.0M guide, and adjusted EBITDA of approximately $2.5M against a $(0.5)M–$1.0M guide. The same release packaged the beat with two simultaneous senior departures: Chief Growth Officer Paulina Klimenko (a 15-year PubMatic veteran, retiring for health reasons and staying through July 2026 for transition) and Americas Chief Revenue Officer Kyle Dozeman (departing for an entrepreneurship opportunity, through end of May with advisory continuation thereafter). PubMatic retained Heidrick & Struggles to search for a consolidated global CRO; the structural read on the May 7 call will be how that consolidation is positioned against the Q1 beat.

PubMatic’s standards-body posture in April 2026 lines up with Magnite’s. Goel went on the record via MediaPost’s Laurie Sullivan calling Amazon’s April 15 donation of the Dynamic Traffic Engine to IAB Tech Lab a signal “about where programmatic is heading,” and PubMatic’s own blog has cited “up to a 10 percent increase in eCPM” from its DTE integration (which moved from closed beta in January 2025 to global production). Six days later, on April 21, PubMatic took a founding seat on the IAB Tech Lab Programmatic Governance Council alongside Magnite, The Trade Desk, Amazon Ads, Disney, and the major holding-company agencies — the council that will write the auction-transparency rules the SSP layer transacts under for the next cycle.
