Why this matters
This is the graduation exam of validation: asking for money or a written commitment before the product exists. Compliments, waitlists, and enthusiasm all cost the customer nothing; a pre-order or an LOI costs something, which is exactly why it is the only signal that reliably predicts paying customers.
What "done" looks like
- 3 commitments in hand: paid pre-orders (even discounted deposits) or signed LOIs stating intent to buy at a defined price
- Each names scope: what they expect, when, at what price
- Asks made to at least 8 to 10 qualified prospects (a real denominator)
- Every "no" and its reason logged, those are your remaining objections
How to do it
- Ask the people who leaned in during solution interviews, they have context and confessed pain.
- Make the offer concrete: "Founding customer: [price, discounted], you get [scope] by [date], direct line to us, cancel anytime before delivery."
- For B2B, offer the LOI path: a one-page non-binding letter, "intends to purchase [product] at [price] upon delivery of [scope]", when payment needs procurement.
- Handle hesitation by downscoping the risk, not the price: smaller deposit, pilot period, refund guarantee. Discounting on the spot teaches them to wait.
- Log every ask, who, response, objection. Three yeses from ten asks is a strong signal; zero from ten is your answer too.
Common mistakes
- Never actually asking, and logging "positive conversations" instead
- Counting free-pilot agreements as commitment (they cost nothing)
- Asking only your two friendliest contacts and stopping at their yes
Real-world examples
- Pebble famously validated its smartwatch by taking pre-orders on Kickstarter after VC funding fell through, the first campaign raised over $10 million from about 69,000 backers, proving demand before the product shipped.
- In B2B, a letter of intent (LOI) or signed pilot agreement has become the standard way to show real customer pull before a product exists, you typically need only a handful of committed companies, not a hundred, to prove the point.
- One documented caution (the "LOI fallacy") is that commitments alone aren't understanding: treat pre-orders and LOIs as a stronger signal than compliments, but pair them with real conversations, the kind you'd have when you interview 10 potential customers.
From a founder's point of view
Compliments are free, so people give them freely; money and a signature cost something, so they mean something. Asking for a real commitment feels rude right up until it saves you months building the wrong thing. Three people willing to pay or sign teaches you more than fifty who say "great idea."
Rule of thumb
Until someone gives you money or signs their name, you have opinions, not customers. Three signatures beat three hundred waitlist emails.
