Ad campaigns executed through Choozle’s software as a service (SaaS) are served on various ad networks, including Rubicon, MoPub, OpenX, Facebook, DoubleClick, Google Display Network, Yahoo, AppNexus, and AOL.

The startup has more than 300 global clients operating campaigns for over 1,000 diverse advertisers, according to cofounder and CEO Andrew Fischer. Customers include Paradise Agency, Digital First Media, Watauga, and Ibotta.

The service works on a subscription basis, ranging from $99 to $1,999 a month.
