StackAdapt works with customers across different business verticals—for example, political campaigns, retailers, B2B, travel, healthcare, and financial services—and helps them place ads in front of target audiences, with inventory including native advertising, display, video, connected TV, audio, and games. The company has built its AI on 'a decade of experience analyzing ad traffic patterns and understanding their evolution,' which it uses to help combat ad fraud and bot traffic.
Cyborg Score Rationale
StackAdapt achieved a $2.5 billion valuation with annual revenues of $500 million following a $235 million equity funding round in February 2025 led by Teachers' Venture Growth. The company demonstrates strong market leadership, consistent profitability alongside growth, and commanding G2 rankings, though it operates in a competitive programmatic advertising market with evolving regulatory and fraud-prevention pressures.
