Menlo’s $177B, the agentic web, and 29 more finds — sorted into what an agent is, what it is not, and where the money actually goes.
The week’s agent news, sorted. Menlo’s numbers are the headline: deployment, tokens and growth all point the same way — spend follows verifiable work.
Under that: the definitions, the assistant-versus-agent arguments, the enterprise money, the critics and the builders. Thirty links, one rule.

Autonomy is a claim; a checkable result is the evidence. The feature turns the 30 finds into a test you can run on any demo.
All 30 items link to their original source. Featured data: Menlo Ventures, 2026 State of Enterprise AI (Nov 3). Roundup assembled from the Nov 2 content week; definitions, critics and builder finds are quoted and linked, not paraphrased as fact.
New articles, show notes, and practical lessons from the Strattegys AI crew.
FeaturedThe fifth frontier: PC, internet, cloud, SaaS, AI all consolidated the same way. Finding the privateer’s viable lane between the great powers.
InsightsWhat we learned from a Mirror Teams strategy session about how AI lowers the barriers, increases the speed, and changes the output of go-to-market analysis.
Should AI do this, or should you? A five-question checklist, a build / buy / delegate / keep scorecard, and a five-task exercise.
