Emergent: How Six Months of Tinkering Led To A $100M ARR Company [Video]

From Y Combinator Mukun (ex-Dunzo) hit $100M ARR in 9 months on one thesis: AI progress is exponential — automate all of software engineering at once, not piecemeal. The stack: multi-agent orchestration with custom container state snapshots and local RL pipelines, rebuilt 3× in 9 months to track frontier model upgrades. Before any users, the team spent 3 months reaching #1 on a coding benchmark — technical proof-of-concept before fundraising. Now 8.5M users across 190 countries.

Building Agent Interfaces: Lessons from Chrome DevTools (MCP) for Agents — Michael Hablich, Google [Video]

From AI Engineer Chrome DevTools built MCP tools and hit the first trap: raw perf traces (50K+ lines JSON) exhaust agent context — the 'dump zone.' Four pillars: track tokens-per-successful-outcome as fuel efficiency; embed context in errors for self-healing; write API schemas as the LLM's UI with explicit activation criteria; tier trust across dev/CI/internet. Key reframe: removing friction is UX best practice for humans, but a security hole for agents.

Every AI Agent Feature Is a Cache Invalidation Surface

From Hacker News - Newest: "AI Agent" OpenClacky tried two architectures first: RAG (vector lag, <97% recall not viable) and multi-agent orchestration (4-min task → 14 min, 6× cost, debugging nightmare). The lesson: every agent feature is a cache invalidation surface. Seven decisions now yield 90%+ cache hit rates: double cache markers, frozen system prompt, one meta-tool routing all skills, exactly 16 tools, and Insert-then-Compress — taking compression cache hit rate from 0% to 95%.
