What Broadsign does
Broadsign provides the content-management and ad-serving software that screen owners use to run digital out-of-home networks, plus programmatic buying and selling tools.
In late 2025 it acquired Place Exchange, a DOOH SSP, combining buy- and sell-side capabilities.
How it makes money
Software licences per screen plus fees on programmatic transactions.
Where it meets invalid traffic
Proof-of-play logs help verify that DOOH ads actually displayed.
