Dreamer Out of Stealth: David Singleton + Hugo Barra Launch Personal Agent OS with $50M Funding

Latent Space·high signal

Formerly known as /dev/agents, Dreamer emerged from stealth as a consumer-first platform where a 'Sidekick' AI builds personalized agents from natural language — an 'agent that builds agents.' Founded by David Singleton (ex-Stripe CTO) and Hugo Barra (who built Android together) with $50M and a developer SDK/CLI. Unusually, most users end up building their own agents rather than using marketplace ones; swyx called it 'the most ambitious full-stack consumer+coding agent startup I've ever seen.'
