Firefly

Firefly operates a media-and-technology model built around monetising proprietary or controlled mobile OOH inventory. It creates value by aggregating screens across taxis, rideshare vehicles, in-car displays, golf environments, and experiential fleet assets, then selling access to advertisers directly and through programmatic pipes. The company supplements media sales with targeting, dynamic creative, attribution, and retargeting capabilities that help advertisers measure outcomes and extend campaigns beyond OOH.

Firefly is a privately held US digital out-of-home advertising company that operates and monetises mobile media inventory, primarily vehicle-mounted digital screens, in-car taxi media, and other experiential fleet formats. Its core customers are brands, media agencies, and programmatic buyers that want targeted urban reach, dynamic creative delivery, and measurement across out-of-home environments.

The company makes money by selling campaign access to its owned or controlled advertising inventory, by enabling programmatic buying of that inventory, and by offering related services such as experiential fleet activations, retargeting, and campaign measurement. Firefly has also expanded through acquisitions, notably Curb Taxi Media in the US and Ubiquitous in the UK, suggesting a consolidation strategy in taxi and mobile OOH media.
