  Adduro

  Denver, Colorado, USA

  Adduro is a streaming advertising platform founded in 2023 by a former media buyer who sought to eliminate the opacity and hidden markups endemic to traditional ad tech. Headquartered in Denver, Colorado, the company operates with a lean team of 11–50 employees and positions itself as a transparent, advertiser-first alternative. It offers connected TV (CTV), streaming audio, display, and online video campaigns, buying inventory directly from major publishers such as Netflix, Prime Video, Disney+, Hulu, Peacock, Roku, and Paramount+, thereby removing middlemen and resold inventory. Proprietary technology includes a real-time bidder (GammaRay), a fraud prevention layer (Hard Check) that blocks over 250 million invalid impressions monthly, and a reporting engine (GammaBurst) that provides publisher-level fractional attribution. The platform also features a patent-pending dynamic audio product (RIVI) and access to over 80,000 data segments from Experian, TransUnion, and LiveRamp. Adduro provides a dedicated team of strategists to manage campaigns and holds monthly reconciliation meetings where platform data is compared against actual sales, refusing to take credit for conversions driven by other marketing efforts.
