Most business ideas feel great in your head. Validation is the work of finding out, cheaply and quickly, whether other people will actually pay for it. Here is a process you can run in a few weeks with almost no budget.
What validation really means
Validating an idea does not mean asking friends whether they like it. Friends are polite. It means collecting evidence that a specific group of people has a specific problem, cares enough to pay to solve it, and would choose your solution.
Good validation ends with a decision: go, pivot or stop. If you cannot imagine any result that would make you stop, you are not validating, you are decorating.
Step 1: Write the idea in one sentence
Force yourself to fill in this sentence: "I help [specific customer] to [solve specific problem] so that [result they care about]." If you cannot be specific about the customer, you do not yet have an idea, you have a topic.
- Bad: "A fitness app for everyone."
- Better: "I help new mothers in their first year get back to exercise in 15-minute home sessions."
Step 2: List the assumptions that must be true
Every idea rests on a few beliefs. Write them down and rank them by how fatal it would be if they were wrong. Usually the riskiest ones are about the customer, not the technology.
- The problem is painful and frequent enough that people already try to solve it.
- They are currently spending money or time on a workaround.
- They would pay a price that leaves you with a margin.
- You can reach them at a cost you can afford.
Step 3: Talk to 10 to 15 potential customers
Interviews are the cheapest and most informative step. Talk to people who match your customer sentence, not to people who are easy to reach. Ask about their past behavior, not about your idea.
Ask questions such as: "Tell me about the last time you dealt with this", "What did you try?", "What did it cost you?" and "What would have to be true for you to switch?" Avoid "Would you buy this?" because people overestimate their own future behavior.
Step 4: Test whether people will pay
Interest is not demand. The strongest signal is money or a concrete commitment. Run the smallest test that asks for one.
- A landing page that explains the offer with a button to pre-order or join a paid waitlist.
- A manual version of the service that you deliver by hand to your first few customers.
- A small paid advertising test sending the right audience to that page, to see what each interested visitor costs you.
Step 5: Check the numbers
Before you build anything, estimate what a customer is worth and what one costs to win. If acquiring a customer costs more than the margin you earn from them, the idea does not work yet, however much people like it.
Also check the basics of the business: the legal requirements in your state, the competitors that already serve this customer, and how long your savings would last at realistic revenue.
Step 6: Decide: go, pivot or stop
Set your decision rules before you see the results, otherwise you will bend the numbers to fit what you hoped for. Write down what result means go, what means change something material, and what means stop.
Stopping is a good outcome. It means you spent a few weeks instead of a year and your savings are intact.

Quick answers
How long does it take to validate a business idea?
A focused effort usually takes two to six weeks: a few days to define the idea and assumptions, one to two weeks of customer interviews and one to two weeks of a small paid test.
How many customers should I interview?
Ten to fifteen conversations with people who really match your target customer is a good starting point. If the answers keep repeating, you have learned most of what interviews can teach you.
Is it enough that people say they like my idea?
No. Compliments are not demand. Look for behavior: people already spending money or time on the problem, and people willing to pre-order, pay a deposit or join a paid waitlist.
