Cheq, a startup focused on preventing ad fraud and ensuring that ads run in brand-safe environments, has raised $16 million in Series B funding.

When the company raised its $5 million Series A last year, CEO Guy Tytunovich contrasted Cheq’s approach with what he called “first generation solutions for ad verification” — rather than identifying fraud and other issues after an ad has already run, he said Cheq is more proactive and can block ads from being served in real time.
