AppsFlyer Lands $1B Series E at $2.7B Valuation; Meta, Google, Moloco, Unity Invest

AppsFlyer, a marketing analytics platform that acts as an independent attribution and measurement referee for mobile app installs and in-app purchases, closed a Series E funding round exceeding $1 billion at a post-money valuation of $2.7 billion. The company is backed by Moloco, Google, Meta, and Unity, which each took minority stakes. AppsFlyer CEO and co-founder Oren Kaniel told Axios: "As AI takes over more of how advertising gets bought and optimized, the signals feeding those systems become the most consequential infrastructure in the industry." The company's most recent raise before this was in 2020; total known funding since 2011 inception is $1.3 billion.

The new round reflects conviction from the biggest platforms in applied AI advertising. Google, Meta, and Moloco—the three most active players in agentic buying and optimization—each chose to anchor stakes in AppsFlyer, signaling that independent, trusted attribution is a choke point in autonomous ad systems. AppsFlyer helps companies measure return on ad spend while protecting user privacy and blocking ad fraud. With $1.3 billion in known funding and a $2.7 billion valuation, the company has matured beyond the hypergrowth stage but remains private.

Kaniel flagged the public markets as the next milestone: "This financing is a step on that path." For practitioners building or buying into attribution stacks, AppsFlyer's investor syndicate—spanning infrastructure (Moloco), the two largest ad platforms (Google, Meta), and a major game engine (Unity)—validates the criticality of neutral measurement in the age of agentic AI optimization. Sales and marketing funding globally stands at ~$4.1B year-to-date 2026, tracking flat to slightly up from recent years but far below boom-era levels.
