Y Combinator's Winter 2026 batch is 60% AI companies (up from 40% in 2024). Dominant pattern: agents replacing SaaS workflows, not copilots inside SaaS. Tensol replaces legacy hotel ERPs entirely.

Salesforce unveiled Headless 360 at TDX, and this is the most aggressive enterprise platform pivot I've seen. Every capability across Customer 360, Slack, Agentforce, and Data 360 is now accessible via APIs, MCP tools, or CLI commands. No browser. No clicking through the Sales...
