Steve Ruiz, creator of tldraw, explains how his free whiteboard tool became the foundation for a commercial SDK business built on high-performance web canvas rendering. The conversation covers a specific and underexplored tension: how SDK and infrastructure companies are exposed to the agentic software wave differently than SaaS companies are.
The most technically interesting thread is what happens when you give an LLM an infinite canvas. Ruiz has already shipped an agent starter kit at tldraw.dev and a demo called tldraw fairies that shows early answers to that question. The internal tooling angle is worth paying attention to: Ruiz has a concrete thesis on where that market goes as agents need persistent, visual workspaces to operate in.
Changelog++ members get 15 additional minutes not in the public feed. The full episode is at tldraw.dev for context on the SDK side, and the agent starter kit is live if you want to build rather than just listen.
