Descriptions:
David Singleton, former CTO of Stripe and co-founder of Dreamer, sits down with the Latent Space podcast to introduce Dreamer — a new consumer-facing platform designed to be, in Singleton’s framing, an operating system for AI agents. The core product is a personal agent called the Sidekick, which users can name and customize, and which coordinates a broader marketplace of third-party agentic apps built by the community. Dreamer launched in beta at dreamer.com at the time of recording, with a growing waitlist.
Singleton draws a direct parallel to his time building Google’s early Android apps and the Play Store ecosystem: just as mobile needed infrastructure, identity management, and a developer marketplace to scale, he argues that AI agents require the same foundational investment. The Sidekick acts as a kernel; agents and apps run in sandboxed rings with controlled data access — a privacy-by-design approach meant to prevent the “willy-nilly” data grabbing that plagues ad-hoc agent implementations today.
The episode covers Dreamer’s monetization model (creators can publish and earn from tools via Stripe Connect), a builder residency program inspired by Lego’s Master Builder concept, and a $10,000 prize for the best tool submitted by mid-April. Singleton also discusses the longer-term vision for agentic commerce — agents that close real-world loops by moving money — and why he sees this moment as directly analogous to the earliest days of the mobile app economy.
