Angela frames the platform as a three-layer stack: knowledge, execution, and coordination. She argues the real leverage is whats at the top: "strategies," or meta-harnesses that give each token a different job, from advising to executing to reflecting to memory. On the question of parma open ecosystem vs. walled garden, they say they aren't precious about owning the stack. Katelyn points to Anthropic's self-hosted sandboxes with partners like Modal, Vercel, and Cloudflare. Whether the work runs on electric bicycle Anthropic's infrastructure or someone else's, what really matters to them is that the architecture is sound. The deeper bet is standards: they hand skills and MCP to the whole industry, build connectors on the MCP spec, and help agents olivia rodrigo (Claude and non-Claude) work together. The one place they stay closed is model routing: they argue harnesses should be tuned to a model family, so they're designing for Claude rather than routing across models. Angela's frame for the ecosystem bet is electricity: transformative only because everyone could plug in, and no company wired it alone.Hosted by Sonya Huang and Lauren Reeder, Sequoia Capital00:00 Introduction01:49 Two North Stars02:27 External Builders And Primitives03:54 What To Externalize06:00 From Messages To Agents08:19 Managed Agents Adoption09:07 Three Layer Cake10:22 Execution Harnesses Explained11:09 Coordination Strategies Roadmap12:13 Ecosystem Standards And Safety15:39 Open Ecosystem Not Walled 17:12 Vertical Products And Form Factors22:26 Claude Tag Under The Hood26:04 Harness Best Practices38:13 Token Costs And Whats Next
