What it is

End-to-end programmatic digital-out-of-home (DOOH) stack: a demand-side platform (Vistar DSP) for buyers, a supply-side platform (Vistar SSP) for media owners, an ad server for automated campaign delivery and yield, and Cortex, a device and content management system (CMS) for signage networks. At acquisition (T-Mobile, Jan 2025), Vistar's network spanned more than 1.1 million digital screens from approximately 370 media owners, serving more than 3,000 brand advertisers globally.

Funding & ownership

Privately held

Wholly owned subsidiary of T-Mobile US (NASDAQ: TMUS), acquired February 3, 2025

Funding raised

Approx. 35.5 million dollars disclosed pre-acquisition venture funding per ZoomInfo; likely an incomplete figure given the company sold for approximately 600 million dollars in 2025. No further funding rounds post-acquisition since Vistar is now a wholly owned subsidiary, not a standalone fundraising entity.

Most recent investors

T-Mobile US (acquirer, 2025); pre-acquisition investor names not independently confirmed in materials reviewed

Vistar is no longer an independent company. Its financial standing should be read as a division inside T-Mobile Advertising Solutions rather than a standalone entity with its own market cap or funding trajectory.

Product architecture

  • 01Vistar DSP: real-time bidding demand-side platform for DOOH, described by Vistar as analyzing daily movement patterns to identify optimal times and locations for a target audience, then bidding only on matching screens. Includes automatic creative transcoding across formats and a creative studio service layer.
  • 02Vistar SSP: supply-side platform for media owners, giving control over which inventory is exposed, pricing, restrictions and creative approval, plus direct connections into major omnichannel DSPs (Vistar names DV360, The Trade Desk, Yahoo, PulsePoint, Nexxen, StackAdapt, Viant, Blis, Adomni, AdQuick, Basis, Displayce, KNOREX and HarmonyAds on its own site).
  • 03Vistar Ad Server: automated campaign delivery and yield engine for media owners, combining impression-based and loop-based scheduling, real-time pacing, and an API suite for orders, venues and reporting. Named ad-serving customers on Vistar's site include Lamar, Clear Channel Outdoor, GSTV, Lyft and T-Ads.
  • 04Cortex: device and content management software (CMS), used for remote deployment, troubleshooting, custom app development (HTML/CSS/JS or pre-built apps), network health monitoring and alerting across a signage network.
  • 05Adstruc: a separate, traditional (non-programmatic) OOH planning and buying platform mentioned in Vistar's own navigation, positioned as simplifying direct/traditional OOH planning on one platform. Not detailed further in materials reviewed beyond its listing as a Vistar product line.

Distinctive asset

One of very few vendors covering the full DOOH stack end to end (DSP, SSP, ad server, and CMS) rather than specializing in one layer. Direct integrations named on Vistar's own site include DV360, The Trade Desk, Yahoo, PulsePoint, Nexxen, StackAdapt, Viant, Blis, Adomni, AdQuick, Basis, Displayce, KNOREX and HarmonyAds on the demand side, and Lamar, Clear Channel Outdoor, GSTV, Lyft and T-Ads on the supply/ad-serving side. Founding team (Provenzano, Ozen, Chadwick) previously built Invite Media, an early display DSP acquired by Google in 2011, which is real relevant pedigree for the DSP layer specifically.

Market coverage

At acquisition (Jan 2025, per T-Mobile and Vistar Media legal-counsel press releases): more than 1.1 million digital screens, from nearly 370 out-of-home media owners, serving more than 3,000 brand partner advertisers globally. A separate, older third-party vendor profile (Domedia) describes operations in more than 20 countries across North America, Europe, Latin America and Asia-Pacific; this was not independently re-verified against a current Vistar source and should be treated as directional.
