Pig.dev is a Y Combinator-backed startup founded by Erik Dunteman, a seasoned entrepreneur with a background in cloud infrastructure and developer tools. Initially accepted into Y Combinator’s Winter 2025 batch, Pig.dev set out to solve a critical challenge in the AI landscape: enabling AI agents to reliably control and interact with Microsoft Windows desktops over extended periods. The vision was to create a robust automation platform that would allow AI agents to perform complex, long-running tasks on personal computers, much like how Browser Use helps AI agents navigate web interfaces. Despite early promise and industry interest, Pig.dev made a significant pivot in May 2025, shifting away from Windows automation to focus on a new product called Muscle Mem. This innovative tool acts as a caching system for AI agents, allowing them to offload repetitive tasks and optimize performance by storing and reusing solutions to common problems. This pivot reflects the startup’s adaptability and responsiveness to the evolving needs of the AI ecosystem, where long-term agent reliability and cost-efficiency remain major hurdles. Pig.dev’s journey has been marked by insightful discussions with Y Combinator partners and industry leaders, who have highlighted the importance of solving computer use for AI agents in professional environments. The company’s developer SDK enables teams to build custom agents, manage connected machines, and even pass control to human operators for sensitive operations, blending automation with human oversight. Today, Pig.dev stands as a testament to the dynamic nature of AI startups, demonstrating how rapid iteration and strategic pivoting can lead to new opportunities in the fast-moving world of AI and automation. Its story continues to inspire founders tackling the next frontier of intelligent agent technology.
