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

Called a start Pig.dev The 2025 ball in the winter of Y Combinator was working on a potential revolutionary idea: Microsoft AI agent Technical Tech to manage the Windows desktop.

But in May The founder announced He refuses techniques and turned his company completely different: Muscle memoA cache system for AI agents that allow you to download repetitive tasks.

The previous first stage YC company, of course, is not something ordinary. What is interesting – and what caused a dynamic conversation on Thursday And a combinator podcast – This pig works on computer use, one of the largest areas that should be solved for agents to be really useful in the workforce. Another company – and another YC Alum – solves the use of browser for browser.

The use of browser has risen to popularity when Chine Agent tools are Manus, Went to viral. Using the browser, use a website buttons and elements to convert more digest to agents that help you to see how the AI’s website will walk and use the website.

YB Cominator Liked the pig, on Thursday, Joint Tom Blomfield, Pight, as the Windows desktop used. Podcast, Amjad Massad, Popular Former and CEO Vibe-coding starting replit.

Massad, Blomfield and YC Partner David Lieb, not watches, the use of a period of time to use for a longer term for hours was still a block who stumbles for agents. As the context window grows, an agent’s accuracy, despite the increase in LLM costs.

“Today, the advice I will give to the founders, using the browser or window, trying to enter the vertical industry, trying to enter the vertical industry,” said Bomfield.

Massad agreed: “The moment of the technology is working, it will be really good, really good,” he said.

Unfortunately, the founder of the pig, Eric Duntemer, now refused to thought. In his post in May, a cloud API product (a conventional way of delivering AI technology) was first explained in his post. However, their clients did not want it. Thus, he tried to sell it as a dev instrument. And they did not want them.

“In the legacy application, which users in the automation space are to give me money and get an automation,” he said. In fact, they wanted to hire a consultant to work for them to work for their Windows Robot Process.

However, Duneman did not want to do one-time projects. Wanted to build developments. So he left the pig and began working on the AI Prevention. Dunteman, Windows Automation, Although HINCH has commented on Windows automation decision later Pig.Dev website and GitHub documents stay available.

However, Dunteman told us that a new tool was inspired by the computer’s use problem. Whipped from another angle. The idea is to allow the agent to download recycled tasks Muscle memo Service, so the agent may focus on the grounds for new problems and outsider.

“Now what we work is also inspired directly and applied to use the computer, only the developer is very optimistic for computer use in the ‘last mile’.

Not to say that no one is working on Windows automation.

Probably the farthest company is Microsoft itself. For example, in April Microsoft has announced Added a computer usage label to Copilot Studio for graphical user interfaces like Windows. This technology was released as a review of a study. Moreover, Microsoft was declared earlier this month Agent tool on Windows 11 Help users manage settings.
