Why a Y Combinator startup tackling AI agents for Windows gave up and pivoted

Pig.dev, a Y Combinator startup, abandoned its AI agent technology for Windows desktop automation after struggling to find product-market fit. Despite working on a potentially revolutionary problem, the founder Erik Dunteman discovered customers wanted consulting services rather than development tools or cloud APIs. He pivoted to Muscle Mem, an AI caching system that helps agents offload repetitive tasks. The story highlights the challenges of building computer use technology for agents, with Microsoft currently leading development in this space through Copilot Studio and Windows 11 features.
