The YC Philosophy

Y Combinator has pioneered a systematic approach to starting companies. Their philosophy revolves around a few core tennets: starting small, building fast, and making something people actually want.

This series distills the most critical lessons from the YC Library and Startup School, organized into a logical progression for any aspiring founder.


The Startup Lifecycle

The journey of a YC-backed startup can be visualized as a focused loop of iteration and growth:


Series Curriculum

  1. Starting a Startup Why you should (and shouldn't) start a startup and the mindset required.
  2. Evaluating Ideas Frameworks to determine if your idea has the potential to become a billion-dollar company.
  3. Business Models Understanding how to capture value and build a sustainable engine.
  4. First Customers How to do things that don't scale to get your first 10 and 100 users.
  5. Build MVP The art of the Minimum Viable Product: what to include and what to cut.
  6. Launching Strategies for broad launches and building momentum.
  7. Tips for Founders Expert advice on survival, burnout, and co-founder dynamics.

Golden Rules from YC

  • Make something people want: If you're not solving a real problem, you're just building a hobby.
  • Do things that don't scale: Recruit your first users manually. Don't wait for them to find you.
  • Write code and talk to users: These are the only two things that matter in the early days.
  • Launch now: If you're not embarrassed by your first version, you launched too late.
