This curriculum takes you from zero to the fundamentals of starting a startup, using talks from founders and investors at Y Combinator and beyond. It is for aspiring founders who have no company yet, and by the end you will know how to choose an idea, talk to users, build a first version, grow it, and fund it.
The steps follow the real order of a founder's journey, from deciding whether to start, to finding an idea, building, growing, funding, and then sustaining yourself for the long run. Video-first learning works here because these lessons come straight from people who built and funded the companies, so you hear the reasoning and the tradeoffs in their own words.
The steps in this curriculum are:
Should you start a startup at all? (3 videos, 95 min)
How do you find an idea worth pursuing? (2 videos, 58 min)
How do you know real people want it? (2 videos, 42 min)
How do you build and launch a first version? (3 videos, 67 min)
What should you build in the AI era? (3 videos, 118 min)
How do you get first users and grow? (2 videos, 54 min)
How do you pitch and fund the company? (3 videos, 65 min)
How do great founders think long term? (3 videos, 90 min)
How do you sustain yourself and your team? (3 videos, 68 min)
Total: 24 videos, 657 minutes of watch time (about 11 hours), and 21.6M combined views.

In short: Start a startup when you feel compelled by a specific problem and can honestly live with the worst-case outcome, because passion and resilience are what carry you through the stress. Your initial motivation matters less than an enduring interest in the problem and the people you work with.

These talks set expectations before you commit, showing that founders come from many backgrounds and that resilience matters more than any stereotype. They also frame how to choose meaningful work, so you begin with clear reasons rather than hype.

In short: Focus on real problems that are urgent, costly, and frequent rather than trendy solutions, and test each idea against questions about market size, competition, and founder fit. Ideas that look hard or boring are often the best opportunities because most founders avoid them.

Both videos give you frameworks to separate real problems from superficially plausible ones and to spot tar pit ideas. Together they turn idea selection into a skill you can practice instead of a lucky guess.

In short: Talk to users at every stage, because they reveal genuine problems even when they suggest bad solutions. Building personal, unscalable relationships with early customers teaches you the market before you try to scale.

One video teaches how to find users and ask open questions that surface problems rather than features. The other shows why manual, unscalable work early on gives you insight and loyalty that scalable tactics cannot.

In short: Build a ridiculously simple MVP, launch it quickly, and iterate on feedback instead of pivoting to new problems. AI tools now let small teams build faster, but learning to code still builds the taste and craftsmanship a good product needs.

These videos take you from planning a lean MVP to actually building it with AI assistance and version control. They keep the focus on shipping something basic fast, then improving it with real user feedback.

In short: Some of the biggest current openings are vertical AI agents that automate specialized, admin-heavy work, which could be larger than traditional SaaS. Software is shifting toward natural-language programming, so founders can build for a market where AI models are core.

These talks map where the opportunities are, from Karpathy's view of Software 3.0 to concrete cases for vertical AI agents. They help you aim your idea at a market that is expanding rather than shrinking.

In short: Find product-market fit and measure retention before spending on growth tactics. Products people spontaneously share, aimed at markets growing quickly, grow because users tell their friends.

One video details how growth teams measure retention and run experiments once fit exists. The other lays out the traits, from an evangelical founder to real momentum, that let a product spread on its own.

In short: Pitch by leading with a clear problem, solution, and insight, stated simply enough that anyone can repeat it. Most businesses should bootstrap, and you should raise venture capital only when you need upfront capital and can grow quickly.

These videos cover how to describe your idea so investors and users understand it, how to decide between bootstrapping and venture capital, and how to apply to an accelerator. Together they demystify the money side of building a company.

In short: Great founders start with a meaningful problem, hold an ambitious long-term vision, and stay flexible on tactics while remaining obstinate about the mission. Customer obsession and constant learning from feedback turn early struggle into durable companies.

These journeys, from Facebook to a venture builder's playbook to DoorDash, show vision and adaptability in practice. They connect the earlier tactical steps to the mindset that carries a company through years, not weeks.

In short: Founders reduce setbacks by protecting sleep, health, and supportive relationships, and by building the resilience to handle rejection. Fair equity and a real seat at the decision table keep the founding team healthy, and even failure leaves valuable skills behind.

One video audits the daily habits that keep founders steady, while another helps technical founders avoid unfair equity and exclusion. A final backstory shows how a failed startup can still lead to a career-defining product.

How long is this startup curriculum?
It runs roughly eleven hours across nine steps, so you can finish it in a week of focused evenings or spread it across a month.
Do I need to know how to code to start a startup?
No, you can start by learning basic coding, using AI vibe-coding tools, or finding a co-founder who codes, but building a first version yourself remains valuable for taste and craftsmanship.
Should I bootstrap or raise venture capital?
Most businesses should bootstrap, since venture capital fits only companies that need large upfront capital and can grow very quickly.
What makes a good startup idea?
A good idea solves a problem that is real, urgent, costly, and frequent, and gives you an unfair advantage, instead of starting from a trendy solution.
How do I get my first users?
Reach out to people you already know have the problem, do unscalable things to serve them personally, and gather feedback to keep improving the product.
Work through the steps in order, watch each video with a notebook open, and after every step write down one concrete action you can take on your own idea. Do not just consume the talks: talk to a potential user, sketch an MVP, or draft a pitch as you move through the material. After finishing, apply to an accelerator, build and launch something small, and return to the growth and fundraising steps as your company reaches each new stage.
