Michael Truell (00:00:00): ... our goal with Cursor is to invent a new type of programming, a very different way to build software. So a world kind of after code, I think that more and more being an engineer will start to feel like being a logic designer, and really, it will be about specifying your intent for how exactly you want everything to work. Lenny Rachitsky (00:00:16): What is the most counter-intuitive thing you've learned so far about building Cursor? Michael Truell (00:00:20): We definitely didn't expect to be doing any of our own model development. And at this point, every magic moment in Cursor involves a custom model in some way. Lenny Rachitsky (00:00:26): What's something that you wish you knew before you got into this role? Michael Truell (00:00:29): Many people you hear hire too fast, I think we actually hired too slow to begin with. Lenny Rachitsky (00:00:35): You guys went from $0 to 100 million ARR in a year and a half, which is historic. Was there an inflection point where things just started to really take off? Michael Truell (00:00:43): The growth has been fairly just consistent on an exponential. And exponential to begin with feels fairly slow when the numbers are really low, and it didn't really show off to the races to begin with. Lenny Rachitsky (00:00:51): What do you think is the secret to your success? Michael Truell (00:00:53): I think it's been... Lenny Rachitsky (00:00:55): Today, my guest is Michael Truell. Michael is co-founder and CEO of Anysphere, the company behind Cursor. If you've been living under a rock and haven't heard of Cursor, it is the leading AI code editor, and is at the very forefront of changing how engineers and product teams build software. It's also one of the fastest growing products of all time, hitting 100 million ARR just 20 months after launching, and then 300 million ARR just two years since launch. (00:01:22): Michael's been working on AI for 10 years. He studied computer science and math at M...

💡 Key Takeaways

  • 1Software engineering is shifting from syntax management to 'logic design' and intent specification.
  • 2Relying solely on foundation models (like GPT-4) is insufficient for high-performance AI tools; custom 'ensemble' models are necessary for speed and context.
  • 3The most effective AI interaction pattern is 'chopping' tasks into small, iterative loops rather than one-shot generation.
  • 4Hiring for high-velocity teams works best with a 2-day onsite work test rather than standard interviews.
  • 5Taste and 'model intuition' are becoming the new differentiating skills for engineers.
  • 6Market ceilings for AI coding tools are much higher than traditional IDE markets because they automate labor, not just edit text.

🎯 Product Strategy

Instead of being a 'wrapper', Cursor combines large foundation models with small, custom-trained models. Small models handle high-frequency, low-latency tasks (like next-edit prediction), while large models handle complex reasoning, creating a seamless user experience.

Core Principles

  • 1.Specialized Small Models: Train custom models for specific tasks (e.g., diff prediction) to achieve <300ms latency.
  • 2.Input/Output Filtering: Use models to pre-search the codebase (context retrieval) and post-process output into valid code diffs.
  • 3.Cost Arbitrage: Offload repetitive inference to cheaper, faster models to maintain economic viability.

⚡ Execution

A workflow framework where complex engineering tasks are broken down into small, verifiable units. The user specifies intent, the AI generates a small batch, the user reviews, and the cycle repeats. This maintains human agency while leveraging AI speed.

Core Principles

  • 1.Decomposition: Break large features into atomic, specifiable steps.
  • 2.Iterative Review: Review AI output after every small step rather than at the end of a massive generation.
  • 3.Human-in-the-Loop: Maintain strict control over the logic while outsourcing the implementation details.

"I would bias less toward trying in one go to tell the model 'here's exactly what I want'... I would chop things up into bits."

🚀 Career & Leadership

As AI handles the 'how' (implementation), the human role shifts entirely to the 'what' (intent and logic). Success depends on 'Taste'—the ability to judge if the output is the right solution—rather than the ability to write syntactically correct code carefully.

Core Principles

  • 1.Intent over Implementation: Focus on specifying exactly how the software should work and look.
  • 2.Taste as a Core Skill: Cultivate the ability to recognize high-quality architecture and UX design.
  • 3.Pseudocode Thinking: Represent logic in high-level English/Pseudocode rather than getting bogged down in syntax.
  • +1 more...

"I think that more and more being an engineer will start to feel like being a logic designer... it will be about specifying your intent."
