What happened

Swivel, a publisher tech startup founded by ad tech veterans, aims to automate manual tasks in publisher ad operations for Connected TV (CTV). The company is developing an 'end-to-end system' of AI agents that handle campaign management from planning to optimization and reporting, with a particular focus on CTV. According to co-founder Joseph Hirsch, Swivel initially focused on yield optimization but is now expanding to the front end of the agentic workflow, including planning, forecasting, and rule-setting for guaranteed deals. The startup addresses fragmentation through the Ad Context Protocol (AdCP), which includes a specification called adagents.json for publishers to declare authorized agents. Swivel plans to expand into retail media, citing the overlap with CTV. The article discusses the challenges and benefits of agentic media buying for CTV, emphasizing its ability to handle non-standard formats and sequential media that are difficult to buy programmatically.

Key questions for investors and operators

When evaluating transactions, technology stacks, or commercial partnerships in this space, we recommend looking closely at three questions:

How is ad load balanced between traditional linear-style pod breaks and non-intrusive native CTV placements (pause, home screen, overlays)?
Are server-side ad insertion (SSAI) and OpenRTB 2.6 signals properly configured to pass pod-bidding and competitive separation parameters?
How are household identity graphs and data clean rooms connected under European GDPR and TCF 2.2 requirements?
