Firefly Systems Inc. is a data-first moving out-of-home (mOOH) advertising network that turns taxis, rideshare vehicles, and other mobility assets into digital and static advertising surfaces across 15+ major North American markets and several countries. Its network of tens of thousands of GPS-connected screens delivers geo-targeted, contextual, and programmatic digital out-of-home (DOOH) campaigns with advanced tracking, attribution, and measurement. Firefly offers digital and static car tops, full and partial car wraps, in-car TaxiTV, around-car activations, and experiential LED and hologram truck formats. Programmatic demand reaches Firefly inventory through third-party DOOH supply-side platforms rather than a Firefly endpoint — its own advertising-solutions page names Place Exchange, Vistar Media, Hivestack and Broadsign, alongside a VIOOH integration, and supports Programmatic Guaranteed and open-marketplace deals. The company is backed by investors including 500 Global, Andreessen Horowitz (a16z), and GV (Google Ventures).
