Michael Truell

Michael Truell co-founded Anysphere, the company behind Cursor, and has articulated a shift in AI programming tools from completing code to managing agents that build software. He was Anysphere’s CEO in May 2025. His personal site describes his work as building SpaceXAI “to advance useful AI.”[3][6][2]

In his February 26, 2026 essay, “The third era of AI software development”, Truell distinguished three ways of working: Tab autocomplete for repetitive coding, synchronous agents directed through prompt-and-response loops, and cloud agents tackling larger tasks independently over longer periods. He framed Cursor’s direction as “helping developers build the factory that creates their software.” In that vision, developers provide direction, equip agents to work independently, and review the results.[6]

Truell’s argument centers on parallel delegation and review. Synchronous agents compete for resources on a developer’s local machine and require ongoing interaction. Cloud agents each run in a separate virtual machine, allowing developers to move to other tasks while the agents iterate and test. Logs, recordings, and live previews make their work reviewable without reconstructing every session. He described the human role as defining problems and setting review criteria.[6]

At publication, Truell reported that 35 percent of Cursor’s internally merged pull requests were created by agents operating autonomously in cloud virtual machines. He also identified practical obstacles: a flaky test or broken environment that a person can work around can interrupt every agent run at scale. Reliable environments and access to the necessary tools and context remained unfinished engineering work.[6]

On April 2, 2026, Truell and Sualeh Asif introduced Cursor 3, a workspace organized around agents working across repositories. They explained that Cursor had originally forked VS Code to control its interface; the new agent interface was built from scratch. Their announcement described cloud agents returning demos and screenshots for verification, with sessions moving to a local machine for editing and testing or into the cloud to continue while the developer was offline.[8]

Before these agent-centered announcements, Truell studied computer science and mathematics at MIT. His personal account of earlier work includes statistical mathematics research, LLM-driven recommendation systems, high-throughput drug pipelines, and programming competitions. Cursor’s initial direction also differed from its later coding focus: Lenny Rachitsky’s May 2025 podcast summary describes an early pivot from mechanical engineering tools to programming, reflecting a larger opportunity and the team’s expertise.[2][3]

An August 2023 exchange with Cursor user Tavi captures an early interface tradeoff. Tavi questioned why Cursor had changed the primary-sidebar icons from vertical to horizontal, adding friction to familiar actions. Truell explained: “Original intention behind pivoting the sidebar was to free up horizontal space for the chat.” He promised an option to restore the old orientation and, on August 30, reported that it was available in version 0.9.0.[4]

In November 2024, Truell announced that Supermaven was joining Cursor. His rationale for joining forces with creator Jacob Jackson and the Supermaven team emphasized building a more useful product faster through purpose-built models and a tailored editing experience. He explained that Supermaven had already shifted toward an editor because extension APIs constrained what its team wanted to build. Cursor would become the core focus, alongside a commitment at the time to maintain the Supermaven plugin.[7]

In his May 2025 Lenny’s Podcast appearance, Truell’s outlook extended to engineering skills. Rachitsky’s summary characterized his view as placing increasing value on taste: deciding what should be built and how it should work, with greater emphasis on high-level design as AI takes on technical execution.[3]
