A practical CG81 guide to validate a business idea: validate demand, define scope, protect your time, price responsibly, and build evidence before expanding.
Validate a Business Idea Before Spending Money
The cheapest business lesson is a conversation before the build.
Before paying for branding, software, automation or a full website, find evidence that the problem is real, frequent enough and important enough for someone to act.
1. Write the riskiest assumption
Do not start with ‘people will love this.’ Write the assumption that could kill the idea: who has the problem, how often it happens, what it costs them, and why the current solution is not good enough.
2. Interview behavior, not opinions
Ask what happened the last time the problem appeared. What did they do? What did they pay? How long did it take? What was frustrating? Avoid ‘Would you buy this?’ Hypothetical enthusiasm is cheap.
Seven useful interview questions
- When did this problem last happen?
- What did you do to solve it?
- What did the current solution cost in money or time?
- What was the most frustrating part?
- How often does this happen?
- What would make you switch from the current solution?
- Who would need to approve or pay for a new solution?
3. Run the smallest useful manual version
Deliver the result manually before building the system around it. If the idea is a service, serve one client. If it is software, reproduce the outcome with spreadsheets, forms and human work first. Automation should scale evidence, not replace it.
4. Ask for a real commitment
A deposit, paid pilot, signed implementation or another meaningful commitment is stronger evidence than a compliment. The amount does not need to be huge. It needs to be real.
5. Set a decision date
Do not validate forever. Choose a date and define three possible decisions:
- Continue: the problem is real and people commit.
- Change: the problem is real but the buyer, offer or price is wrong.
- Stop: evidence is weak and another problem deserves your time.
The MNS Validation Score
Problem frequency × Urgency × Current workaround × Budget × Willingness to commit.
Give each factor a simple 1–5 score. The score is not science. It forces you to compare evidence instead of falling in love with the idea.
What counts as strong evidence?
Repeated pain, an existing workaround, current spending, urgency, access to the buyer and a willingness to commit are all stronger signals than likes, survey compliments or friends saying the idea is cool.
Spend after the evidence
Once the signal is strong enough, then decide what deserves investment: domain, branding, automation, software, paid acquisition or a larger build.
Evidence first. Spending later.
