Sean Muller
Founder & CEO at ispot tv
Sean Muller founded iSpot.tv in April 2012 and has been CEO continuously since. He scaled the company from a TV ad catalog into one of three alternative national TV-currency providers JIC-certified alongside Comscore and VideoAmp, and closed a $325M Goldman Sachs Asset Management investment in April 2022 at a valuation above $1 billion.
Sean Muller is one of the small group of operators who have shaped the post-Nielsen era of TV measurement. He founded iSpot.tv in 2012 with a deceptively narrow premise — a complete catalog of every TV ad airing in the U.S. — and over the next decade pulled the company into the center of the alternative-currency contest now reshaping how national TV is bought and sold. The Goldman Sachs investment in 2022 anchored that effort financially; the JIC’s national-currency certification in August 2024 validated it methodologically.
We track Muller because iSpot’s trajectory under his continuous tenure is one of the load-bearing storylines in the measurement beat. He remains an active public voice on AI in TV measurement and the mechanics of cross-platform attribution, and the company’s strategic moves — partnerships, methodology disclosures, currency certifications — flow from his desk.
