Minimum Viable Product: Validate Your Startup Idea for Less than $1,000
Michael Karnjanaprakorn · Founder, Skillshare
Twenty-three minutes from Skillshare's own founder on how he validated the idea for less than $5,000, worth watching once and forgetting the runtime.
Michael Karnjanaprakorn, Skillshare's co-founder, teaches this class the way he says he pitched Skillshare itself: fast, blunt, and short on ceremony. The whole course runs under 25 minutes across six lessons, and the arc is simple. Define MVP, tell the Skillshare origin story as the case study, compress your idea into one sentence, run interviews without arguing with the answers, build the smallest possible test, then repeat the cycle in units of ten.
The Skillshare story is the spine of the class, and it is the best part of it. Karnjanaprakorn contrasts his prior experience at Behance, where a product called Action Method took nine months to build only for the team to discover that one feature carried all the usage, against how he launched Skillshare itself: no custom ticketing system, just a linked Eventbrite page, a poker class he taught himself, and six students recruited by email. That contrast between the "waterfall" build-everything approach and the borrow-what-exists approach is a genuinely useful mental model, not just a war story.
The interview lesson is the most actionable single stretch of the course. The instruction is specific: ask people why an idea will not work, then stop talking. Karnjanaprakorn frames rebuttal as the instinct to fight, calling it falling into a "Steve Jobs trap" where a founder assumes the listener does not understand the vision. He also gives a workable rule for reading the results, that an objection repeated by 10 to 15 people in a row is a signal worth acting on rather than noise to argue past. It is a small technique, but it is concrete enough to use the next day.
Where the course thins out is anywhere it promises a method rather than a story. The "how to build your MVP" and "iterate and test" lessons repeat the restaurant analogy (taste-test dishes, invite 10 friends over, rent a dead Monday-night venue) without ever landing on a framework a viewer could apply to a different kind of business without translating it themselves. The ten-times-ten level structure is memorable, but it stays at the level of an anecdote about Skillshare's own growth rather than a checklist. There is no worksheet, no interview script, no template for defining what a level even means for a specific idea.
The course also never engages with a tech-heavy or physical-product idea in any depth, despite the blurb's promise to cover "a tech startup or a new restaurant." Everything after the restaurant example returns to Skillshare's own early growth tactics, like the Kickstarter campaign and the "why college is overrated" op-ed that generated an email list.
For a beginner who has an idea and has never once tried to get honest feedback on it, the course earns its short runtime. It reframes validation as a scrappy, personal, repeatable habit rather than a business-plan exercise, and the interview-listening advice alone is worth the twenty minutes. Anyone looking for a repeatable process, sample questions, or help building an actual MVP will need a second, more structured resource after this one.
The standout
The 'game with levels' structure, where each stage of validation has an explicit 10x goal (1 teacher and 10 students, then 10 and 100), turns a vague idea like 'talk to customers' into a concrete, repeatable ladder.
What you will learn
- How to compress a business idea into a single 'X for Y' comparison sentence that gets fast, honest feedback
- How to run a customer interview without rebutting or defending the idea, so people actually tell you the truth
- How to break MVP progress into stepped goals that multiply by ten (1 teacher/10 students, then 10/100, and so on)
- How to fake or borrow existing infrastructure (Eventbrite instead of building a ticketing system) to test demand cheaply
- How to read repeated objections across 10-15 conversations as a signal worth acting on
- How to accept doing unscalable, manual work early (personally onboarding every teacher and student) without over-engineering too soon
Best for: A first-time founder who has an idea but has never run a customer interview or thought about staging validation before writing code or signing a lease.
Skip it if: Anyone who has already read Lean Startup or The Mom Test, or who wants a step-by-step interview script, financial model, or MVP-building tutorial rather than a founder's origin story.
