Introduction to AI Agentic Tech
A startup called Pig.dev, which was part of Y Combinator’s Winter 2025 batch, was working on a revolutionary idea: using AI agentic tech to control a Microsoft Windows desktop. This technology had the potential to change the way we interact with computers. However, in May, the founder announced that he was abandoning this project and pivoting his company to something entirely different.
The Pivot to Muscle Mem
The new project, called Muscle Mem, is a cache system for AI agents that allows them to offload repeatable tasks. This means that AI agents can focus on more complex tasks and leave the repetitive ones to the cache system. The founder, Erik Dunteman, decided to pivot his company after realizing that his customers didn’t want the original product as a cloud API or a dev tool. Instead, they wanted to hire a consultant to make their desired Windows robotic process automations work for them.
The Importance of Computer Use
Computer use is a crucial area that needs to be solved for AI agents to be truly useful in the workforce. Another company, Browser Use, is working on a similar problem, but for browsers instead of Windows desktops. Browser Use scans the buttons and elements of a website to turn them into a more digestible format for AI agents, helping them navigate and use the website. The founder of Pig.dev was likened to the founder of Browser Use, as both companies are working on similar problems.
The Challenges of Computer Use
During a Y Combinator podcast, the challenges of computer use were discussed. The partners talked about how long-term computer use of hours, rather than minutes, is still a stumbling block for AI agents. As the context window for reasoning grows, an agent’s accuracy wavers, and the costs increase. The partners suggested that founders should take either Browser Use or Windows automation and try to apply it to enterprise or a vertical industry.
The Future of AI Agentic Tech
The founder of Replit, Amjad Masad, agreed that the moment the technology works, companies like Browser Use and Pig.dev will do really well. However, Pig.dev’s founder has already given up on the idea of Windows automation. Microsoft is also working on computer use tech, and has announced the addition of computer use tech to Copilot Studio for graphical user interfaces like Windows.
Conclusion
The story of Pig.dev and its pivot to Muscle Mem is a fascinating one. It highlights the challenges of working with AI agentic tech and the importance of solving the problem of computer use. While Pig.dev may not be working on Windows automation anymore, the problem is still being tackled by other companies, including Microsoft. The future of AI agentic tech looks promising, and it will be interesting to see how it develops in the coming years.
