The napkin test is a way to check a startup idea with paper, a phone and Instagram, without writing a single line of code. The idea is written as answers to 5 questions, turned into a short video and shown to the market with small targeting.
Most startups fail because they build a product the market does not need. The founder spends 6 months to 1 year building, and then finds out that nobody pays. The napkin test shows this in a few weeks.
In short:
- You need: a phone, an Instagram page, paper.
- 5 questions → short video → targeting → conversations.
- Every conversation is material for the next offer.
What are the 5 questions?
Write the idea as answers to these questions:
- What is your startup?
- Whose problem does it solve, and what problem is it?
- What exactly is the solution?
- What does the customer achieve as a result?
- How much benefit do they get from it?
If you cannot answer one of the questions clearly, that is the first signal. The idea is not yet ready even in your own head.
How do you make the video?
Shoot a 30–60 second video on your phone. The script is the five answers. At the end, add proof: a similar international example or your own case. Then a CTA:
"Leave a + in the comments and we'll show you the demo."
You don't need fancy editing. At this stage you are testing demand, not the creative.
Targeting and conversations
Post the video on Instagram and run it to a target audience with a small budget. Talk to every person who responds yourself, as the founder. Don't hand this to an agency or an operator: at this stage the most valuable thing is the customer's own words.
There is no such thing as "I couldn't sell, it didn't work out." Record every meeting. It becomes a cheat sheet for the next offer.
How do you judge the result?
There are three kinds of results:
- PMF sign — people are ready to pay and pay in advance.
- Pivot — there is interest, but in something else.
- Kill — nobody is interested.
Don't be afraid of the third option. A test of $3,000–$4,000 saves you from losing $20,000–$30,000. Details: Go-To-Market: 6 stages.
How has this method worked in real cases?
From our projects that went to market before the product was ready:
- Nasiya365: with no product yet, $1,000 in ads → 22 paid wishlist entries and 12 sales × $5,000.
- MySchool: $1,115 → 215 leads, 10 customers on the waitlist before launch, 22 sales in total.
- Tuzuk AI: $300 → $3,000+ in subscriptions in 10 days.
These numbers started with a simple video and the right offer.
Conclusion
In short, write down the demand before you write code.
- Answer the 5 questions.
- Shoot a video on your phone.
- Launch with small targeting.
- Talk to every interested person yourself.
- Based on the result: continue, pivot or stop.
