Office buildings in the DOOH ecosystem
Office building DOOH commands above-network CPMs because the audience archetype is exceptionally specific: working professionals in the 25–55 age range, daytime peak audience, with concentrated dwell at elevator banks and lobbies. The Trillboards office building footprint spans premium Class-A buildings, with NYC and LA accounting for the majority of US inventory. Floor CPM of $5.08 USD positions this category in the top tier on the network, only bars, casinos, and night clubs clear higher. Buyer demand concentrates in B2B (financial services, business software), premium consumer (luxury automotive, financial cards, premium consumer technology), and dining (corporate lunch programs, after-work venues).
How the buy executes at office buildings
Each screen runs the Trillboards kiosk app on an open OpenRTB 2.6 connection to our SSP. Roughly every 45 seconds, the device fires an ad request carrying the IAB DOOH inventory descriptor, venue category, location, screen format, plus the live audience measurements from the on-device CV pipeline.
Demand-side platforms bid in under 100 ms. The winning creative ships back, plays in the device's native VAST player, and confirms playback with a signed proof-of-play receipt. Those receipts reconcile daily against partner-reported numbers, which is the record we bill against.
We serve first-party and third-party VAST, OMID viewability where the creative declares it, and device-signed proof of play, meeting the OAAA measurement standards and the IAB DOOH 1.0 specification. Buyers on our OpenRTB endpoint target office buildings through the IAB Audience Taxonomy and the Trillboards segtax=600 namespace, and receive no per-screen identifiers in the bid request.
If you own the venue
Commercial property managers host Trillboards screens in elevator banks, lobby waiting areas, and floor reception. The screens deliver programmatic ads during business hours and switch to building-info content (event listings, weather, transit) during off-hours.
Where these numbers come from
Screen counts, floor CPM, daily impressions and city rankings are aggregated from the Trillboards PostgreSQL system of record (earner_screens, filtered to status = 'approved') joined to the venue taxonomy, snapshotted 2026-05-11 and rebuilt monthly. Floor CPM is the screen-level minimum; cleared CPMs typically run 20–40% higher with demand. Audience index, price and market count come from the live curated catalogue. This page publishes no per-screen, partner or device identifiers.
