The Varosity AI GTM Report

MCP's biggest upgrade ships tomorrow, Claude Opus 5 makes long-running agents safer, buying agents start moving real money, China writes the first AI-agent rulebook, and HubSpot brings the agent fleet to GTM — plus why AI disclosure is now a GTM problem.

Show Notes

Episode 48. Today's read on where A.I. meets go-to-market — Monday, July 27, 2026. The agent stack grew up all at once: the protocol underneath every A.I. agent ships its biggest revision, a frontier model puts a hard number on agent security, buying agents start moving real money across borders, China writes the first binding agent rulebook, and HubSpot pulls the whole fleet into the CRM. Plus: why the E.U. A.I. Act's August 2 disclosure deadline lands on the brand that publishes A.I. media — not the model that made it.
