How to validate a business idea in 14 days

Most new businesses don't fail because the founder couldn't build the product. They fail because not enough people wanted it at the price it had to sell for. Validation is how you find that out early, while it's still cheap to change your mind.

Here's the same two-week sprint we run with every BizBakers founder.

Days 1–2: Write down what you believe

Before you talk to anyone, put your guesses on paper. Write one sentence for each:

• Who has the problem? Be specific. "Busy parents" is too broad. "Parents of kids in travel sports who drive to weekend tournaments" is something you can test.
• What is the problem? Describe it in the customer's words, not yours.
• How do they solve it today? Every real problem already has a workaround, even if it's a spreadsheet or doing nothing.
• What would they pay? Pick a number. You'll test it later.

These are assumptions, not facts. The rest of the sprint is about proving or breaking them.

Days 3–7: Talk to 15 real people

Find people who match your customer description and ask for 15 minutes. Friends and family are fine for practice, but they're too nice to count.

Good questions are about the past, not the future:

• "Tell me about the last time this problem came up."
• "What did you do about it?"
• "What did that cost you, in time or money?"
• "What have you already tried?"

Avoid "Would you buy this?" People say yes to be polite. What they've already done and spent is far more honest.

If nobody can remember the last time they had the problem, it probably isn't painful enough to build a business on.

Days 8–9: Size up the competition

Search for every company solving the same problem, including indirect ones. For each, note the price, who they target, and what reviewers complain about. Those complaints are often your opening.

No competitors at all is usually a warning sign, not a win. It can mean there's no market.

Days 10–12: Test the price with a real ask

Talk is cheap. Now ask for a small commitment:

• A simple landing page with a waitlist or preorder button
• A deposit for an early version
• A signed letter of intent for a business customer

Count how many people take a real step. A handful of signups from strangers tells you more than a hundred "sounds cool" comments.

Days 13–14: Make the call

Look at what you learned and choose one:

1. Go. The problem is real, people pay to solve it today, and some took a step toward buying.
2. Adjust. The problem is real, but your customer, product, or price needs to change. Run the sprint again.
3. Stop. Nobody felt the pain. That's a win too. You just saved months.

Keep your evidence

Save your interview notes, competitor list, and test results. If you apply to BizBakers, this is exactly what we want to see, and strong evidence moves you up the list.
