Apostra Bets on Agentic Ad Layer
Scope3 has rebranded as Apostra, pivoting from its original carbon emissions calculator mission to focus on enabling agent-to-agent ad buying and selling. The company, led by adtech veteran Brian O'Kelley, has been building agentic advertising infrastructure since early 2025, including the Ad Context Protocol (AdCP) open standard and a platform that allows AI agents to negotiate and execute media buys. Apostra has already managed $1.2 million in media spend over the last three months, with clients in the U.S., U.K., France, Brazil, the Netherlands, and South Africa. The company faces competition from the IAB Tech Lab's AAMP 3.0 standard, which also aims to standardize agentic media buying. O'Kelley acknowledges the shift away from sustainability but argues AI is the biggest growth area. The article questions whether the industry needs such a neutral layer or if open standards suffice.
- Scope3 rebranded to Apostra, shifting focus from sustainability to agentic advertising.
- Apostra's platform manages $1.2 million in media spend over the last three months.
- Apostra launched Ad Context Protocol (AdCP) as an open standard for agent-to-agent media transactions.

AI Agents Increasingly Handle Ad Dollars
The article discusses the growing but still experimental use of AI agents in advertising. Companies like Apostra, The Trade Desk, PubMatic, Magnite, and Kargo are developing agentic systems for media buying. Apostra has handled about $1.2 million in ad buys over three months, and Rouge Care reported a fivefold ROAS on CTV ads via PubMatic's AgenticOS. However, highly autonomous deployments represent less than 5% of marketing use cases in 2025. Protocols like AdCP, AAMP, and Amazon's MCP are emerging, but fragmentation risks interoperability. Responsibility for agent decisions remains unclear, and premium advertising remains relationship-driven.
- Apostra has handled automated media buys totaling about $1.2 million over the last three months.
- Rouge Care spent $25,000 on CTV ads and drove over $125,000 in attributable sales via PubMatic's AgenticOS.
- Highly autonomous deployments represent less than 5% of all marketing use cases in 2025, per Gartner.
