What's this about?
Sequoia's Training Data podcast (Jul 14) hosts Anthropic's Katelyn Lesse and Angela Jiang on "Building an Ecosystem, not a Walled Garden" — how Anthropic thinks about platforms, partners, and developers rather than locking everything into first-party products.
What exactly is a "walled garden"?
A walled garden is a platform where the owner controls everything inside (Apple's App Store is the canonical example). The alternative — an ecosystem — grows value by letting outsiders build on your foundation (MCP, Skills, the Agent SDK are Anthropic's moves here). For AI labs this is a live strategic fork: capture all the value yourself, or become the substrate others build on.
Why is it worth noting?
Fresh episode, no discussion metrics yet. It pairs neatly with today's Ode scoop — Anthropic simultaneously courting an open ecosystem *and* building a captive services channel.
