Business validation is the process of collecting enough evidence to decide whether a defined customer will pay for a specific outcome through a model that can operate sustainably. It is not a search for compliments, followers or a perfect forecast.

The decision you are trying to make

At the end of 90 days, choose one of four actions: proceed, revise the offer, change the target segment or stop. Define the evidence required for each decision before beginning. This reduces the temptation to reinterpret weak signals after investing time and money.

Days 1-15: define the problem and customer

Write a narrow problem statement: For [specific customer], [situation] creates [measurable cost or frustration] because [current alternative is inadequate].

Interview people who recently experienced the situation. Ask what happened, what they tried, what it cost and how they chose an alternative. Avoid presenting your solution too early. Statements about past behavior are generally more useful than predictions about a hypothetical purchase.

Create a research log that separates direct evidence, interpretation and unanswered questions. Ten thoughtful interviews can reveal patterns, but they do not prove market size. The objective is to improve the hypothesis and the next test.

Days 16-30: map alternatives and willingness to switch

Customers already solve the problem somehow, even if the alternative is delay, manual work or doing nothing. Compare alternatives on price, effort, risk, trust, speed and switching cost.

Draft a clear offer containing the outcome, scope, delivery method, price and conditions. Test comprehension before persuasion. Ask participants to explain the offer in their own words. If they misunderstand it, advertising will amplify confusion rather than demand.

Days 31-45: test a real commitment

A waiting-list form is a weak signal unless joining requires meaningful effort. Stronger tests include a refundable deposit, paid pilot, signed letter of intent, scheduled implementation call or introduction to the budget owner.

Use one landing page and one primary call to action. Track source, visit, qualified lead, checkout start and purchase. Do not create ten versions before the basic offer can attract one credible commitment.

Days 46-60: calculate unit economics

Estimate contribution margin per customer:

Revenue - variable delivery cost - payment fees - support cost - expected refunds = contribution margin.

Then estimate customer acquisition cost by channel and the working capital required before payment. Include founder time at a realistic replacement cost. A product can be popular and still be economically fragile.

Build three cases: conservative, base and upside. State every assumption. A model is useful because it exposes what must be learned, not because its spreadsheet looks precise.

Days 61-75: deliver a controlled pilot

Run the smallest version that produces the promised outcome. Record onboarding time, completion, support requests, failures and the customer’s evidence of value. Ask what nearly caused them to stop and what they would change before recommending the offer.

A pilot should test delivery risk as well as demand. If every customer requires custom founder intervention, the offer may be consulting rather than a scalable product. That can still be a good business, but it needs the correct price and operating model.

Days 76-90: make the launch decision

Review the pre-defined thresholds. Useful evidence includes paid conversion, gross contribution, delivery time, repeated customer language, retention or completion, referrals and support burden.

Write a short decision memo:

  • what the team believed at the start;
  • evidence collected;
  • assumptions confirmed or rejected;
  • economics under current conditions;
  • main unresolved risk;
  • proceed, revise, pivot or stop;
  • next test and its owner.

Stopping a weak idea is a successful validation outcome. It preserves capital and attention for a better opportunity.

Legal and operational setup

Once the evidence supports launch, complete the registrations, tax, banking, insurance, licensing and local compliance steps that apply to the business. Requirements depend on location, structure and activity. The U.S. Small Business Administration guides cited below illustrate the categories, but founders must use the rules of their own jurisdiction.
