Kagan compresses early business discovery into a weekend. Start by listing problems from daily life, disproportionate spending, cobbled-together solutions, or tasks avoided for weeks. Prefer a problem inside your existing interests and network. Use rough signals such as Google Trends, audience counts, and category spending to establish that meaningful demand exists. Then calculate simple unit economics: selling price minus costs, and the number of sales required to reach the target. Build only enough of the offer for a buyer to understand it, such as a Google Doc with pictures and a price. Contact a Dream 10 list and seek payments or refundable deposits. Three paying customers are Kagan's validation threshold. Only after fulfilling the first promise should the founder repeat, improve, or scale.
Origin
Kagan walks through Jake's golf-trip business and AppSumo's first weekend as demonstrations of the method in Million Dollar Weekend.

How to run it
- 1
Mine problems you know
List what went wrong during breakfast, lunch, and dinner, what consumes unusual spending, what you cobble together, and what remains avoided on your task list.
Pro tip Favor a problem connected to your interests, expertise, or network.
Watch out A personally interesting problem still needs paying demand.
- 2
Check the market quickly
Use search trends, audience size, category spending, and public market signals to see whether at least a million dollars is already spent in the area.
Pro tip Seek directional confidence, not a research dissertation.
Watch out More research can become another way to avoid asking customers.
- 3
Run the one-minute model
Estimate price, direct costs, profit per sale, and how many sales produce the target.
Pro tip Turn revenue dials such as price, repeat purchases, and additional products when the required volume is unrealistic.
Watch out Do not hide weak unit economics behind a large market.
- 4
Create the minimum offer
Make the idea understandable with a document, picture, landing page, advertisement, or marketplace listing.
Pro tip Show the experience and state a specific price.
Watch out Do not build the complete product before testing payment.
- 5
Build the Dream 10
List ten reachable people who experience the problem and can evaluate the offer.
Pro tip Start with people in your existing zone of influence.
Watch out Easy prospects are not invalid prospects.
- 6
Ask and listen
Use LOT to explore the problem, present the option, and request payment or a refundable deposit.
Pro tip After stating the ask, remain silent.
Watch out A promise to buy later is a rejection, not validation.
- 7
Apply the three-customer gate
Treat three real customers in the weekend as evidence that further investment is warranted.
Pro tip Record objections from every no to improve the offer.
Watch out Do not interpret compliments or survey enthusiasm as purchases.
- 8
Deliver before scaling
Fulfill exactly what the first customers bought, learn from the manual experience, and then repeat it.
Pro tip Use high-touch manual delivery to collect customer feedback.
Watch out Do not start an app or solve scale before delivering the first offer.
In the wild
Jake chose high-end golf trips, drafted a Google Doc showing the experience and price, called golfers he knew, and requested refundable deposits. He collected five deposits totaling $500 within 48 hours.
→ Wallet evidence justified organizing the first trip without first building an app or full operation.
Kagan cold-emailed Imgur, arranged a discounted offer, obtained free Reddit ads, added a PayPal button, and manually emailed codes from Gmail. The first sale was $12.
→ A weekend test confirmed demand before AppSumo had an engineering backend or large team.
Common mistakes
Building before asking
A polished product can consume months before the founder encounters real payment behavior.
Counting promises as sales
A prospect who says they will buy later has not validated the offer with their wallet.
Solving scale before delivery
Apps, automation, and delegation distract from fulfilling the first promise and learning from it.
Is it for you?
Best for
A new product or service that can be represented, presold, advertised, or listed on a marketplace before full construction.
Not ideal for
Regulated, dangerous, or irreversible offerings where taking payment before delivery would be unlawful or unethical.
From the transcript
“Just right fucking now, what's the smallest action you can take that will get you momentum?”
“I generally say three people on the weekend. If you can get three customers, to me that's validation.”
“A promise is a rejection.”
