OpenAI's DevDay Is HUGE For Marketers: New Marketplace, Plugins Are Big, and Dots

👉 Single Brain - Revenue agents to scale faster using our unified intelligence layer. https://www.singlebrain.com

OpenAI's DevDay 2026 opens new ways for marketers to get discovered and build useful workflows. I walk through Dots, plugin discovery, Sign in with ChatGPT, the enterprise Marketplace, Decisions API, and Agents API, then explain what these changes could mean for AEO, SEO and paid media.

The opportunity: turn a workflow people need into something they can find and use. Access depends on the product, plan, partner and market. The enterprise Marketplace is a procurement channel; plugin discovery and paid ads are separate routes. Examples and forecasts are my analysis, not a promise of rankings or revenue.
