MiQ has expanded its Sigma tool by introducing new AI-powered planning and measurement capabilities. Since Sigma’s launch a year ago, the technology has powered more than 40,000 campaigns for more than 2,300 advertisers. MiQ said that Sigma delivers a return of $2.22 for every $1 spent when compared to standard programmatic campaign setups. Sigma now allows marketers and agency partners to curate audiences and personas to target, plan, activate and measure campaigns across digital media channels.
