Ad tech trims bloat as efficiency sparks C‑suite exits
Digiday reports consolidation and efficiency drives across ad tech as companies pursue targeted M&A, open-source tooling and leadership reshuffles. Viant announced an intended $40 million acquisition of audience measurement firm TVision, combining it with its IRIS ID to offer buy‑side CTV signals (who was in the room, co‑viewing and eyes‑on‑screen). JWX (the Connatix–JW Player merger) bought True Anthem to add AI-powered social publishing. IAB Tech Lab open-sourced Amazon Ads’ Dynamic Traffic Engine to let DSPs signal bidding preferences to SSPs, aiming to reduce bidstream waste. Supply-side firm Magnite reported several senior exits (including CMO, CPO and CSO) and a CFO retirement plan, signaling a more commercially driven product focus. The briefing also highlights Reuters/Integral Ad Science findings on keyword blocking and wider momentum toward “agentic” AI in programmatic buying.
Deals and product shifts affect CTV measurement, programmatic efficiency (IAB Tech Lab open‑source work) and SSP commercial strategy; these developments have medium industry impact on measurement, bidstream waste and vendor positioning.

OpenAI's Measurement Gaps Keep ChatGPT Ads Budgets at Test Level
Seven months after OpenAI introduced ads in ChatGPT, marketers still face measurement hurdles, as agencies like Accuracast report discrepancies—zero conversions despite form fills and 100 clicks vs. 20 tracked internally—along with 24-36 hour delays and a lack of demographic or prompt data. Legal concerns about OpenAI's terms and data use deter many from enabling conversion tracking, slowing custom audience adoption. Test budgets range from £10,000 to £30,000, with clients spending under $100,000 monthly on ChatGPT versus $10 million on Google. Third-party measurement through partners like AppsFlyer and Adjust is deemed essential, though limited. Meanwhile, DoorDash expands retail media by partnering with Macy's, Timberland, and others, the Trump administration spends millions on pro-Trump ads, Swap Commerce acquires Vizby, and OpenX hires John Rogers as SVP of Global Publisher Development. OpenAI declined to comment.
