What It Is

A 5-week online course aimed at:

  1. understanding LLMs deeply
  2. figuring out what you can build with them for your startup (e.g., internal tools, AI features, new AI products)
  3. learning the basics of building so you could prototype a v1 yourself and then hand off to engineers/CTO

This course is designed for non-technical founders. That being said, ~20% of our students so far have been technical and they all enjoyed it too. If you’re technical and not sure whether you should take this class or not, email us and we’ll help you decide.

Course stats

as of Mar 2026

  • 4 years
  • 12 cohorts
  • 170 students (mostly YC founders, including founders of top YC companies like Daily, Mux, and Codecademy)
  • several founders started new companies after taking this course, one got into YC; explore outcomes here
  • tons of positive reviews, see for yourself here
  • 100% completion rates for c9 & c10

How It Works

  • Small groups of 7-12 founders
  • structured, well-researched curriculum, updated as of Mar 2026
  • hands-on, experienced instructor (YC founder)
  • Weekly speakers like:
    • Gordon Wintrob (Co-Founder & CTO at Newfront (acquired for $1.2bn), 2x YC alum). See Gordon’s previous lecture here
    • Vaibhav Gupta (CEO @ Boundary YC W23, ex-Google, ex-Microsoft; worked on HoloLens & Face ID). See Vaibhav's previous lecture here
    • Kwindla Hultman Kramer (Co-founder & CEO of Daily YC W16, creators of Pipecat, top YC company). See Kwindla's previous lecture here
  • SOTA learning practices like active recall, spaced repetition, socratic questioning, etc.
  • assignments and group calls to keep you accountable
  • course project!

Reviews

I can’t speak highly enough about this course. As a technical cofounder who has attempted to keep my skills sharp, I have generally kept up with the progress of LLMs but have also had trouble parsing the good information from the hype. Before the course, I had a basic understanding but did not quite see where the true value of the technology beyond a “better google” or “content generator”. I’m now excited about the tangible benefits I see from it not only in assisting my day-to-day workload, but also in how I can integrate it into future projects. As a bonus, Vasili, provided a wonderful framework for improving my learning skills. This wasn’t just a benefit to getting more out of the course, but to improve recall and retention in general. The last thing I would highly recommend is truly devoting time to the course. With the learning methodology, lectures and materials, you want to give yourself the time to truly absorb and explore to get the most out of the course.

Just wrapping up the cohort. Loving it! Recommended to our 7,000 person company. I had been playing around with vibe coding before the course & hitting a wall at certain points. The course has enabled me to take a step back & understand what is going on under the hood to help me work with the tools better. I also now have a much better understanding of the end to end stack - which helps me figure out which pieces to put together when building. Highly recommend 🙂

Full recommend here for Vasili Shynkarenka’s course! As a non-technical person, I was looking for a way to unlock my brain to learn how to use these tools and also at a higher level how to even think about what they really are. Vasili used the analogy of installing some new software in my noggin to figure out how to work with this hardware. I’ve learned a ton already, am working on a pretty exciting side project as part of the program and will continue to implement some of the learning techniques in my life even outside of this subject. Really great course and I think well worth the price of admission if you're looking to level up your understanding and learn some practical skills in the space! Also great to see a few fellow S13 founders on the zooms!

Syllabus

Basically we go over the last 6 years of LLM evolution and build up your understanding gradually, from base models like gpt3 to assistant models (+tools +multimodality) to reasoning models & agents that really started working in late 2025, all the way reinforcement learning as 2026 SOTA (esp. in domains with verifiable rewards, like coding).

See the full syllabus here.

In the last two weeks of the class, you will build a project, which usually is some piece of software that leverages LLMs (e.g., internal tool, AI feature, new product prototype). See some examples of what students build in the outcomes section above.

Logistics

  • fully remote
  • 5 weeks, ~1-2h a day to make sure it really sinks in and make progress on projects
  • 3 weeks of theory, ~2 weeks of project work
  • 60% async (reading, watching, tinkering, assignments, etc.) and 40% live (speaker lectures, group discussions)
  • live lectures and group calls are on Thursdays and Fridays at 9 am PT

Note: you really need to allocate at least 1h per day to the course, otherwise it won’t work. As I like saying, “1h a day or stuff fades away.” Karpathy explains why in this twitter thread.
