Startup validation hub
Startup Idea Validation
Startup validation means testing whether a real, painful problem exists and whether people would act on a solution before you spend months building one. Start with customer discovery, look for a repeated pain point, then test willingness to pay.
What you’ll learn
- Find problems people already try to solve
- Plan useful customer interviews
- Test whether customers will pay
- Recognize meaningful demand signals

Start with the fundamentals, then move from customer discovery to a concrete demand test.
Essential guide
How to Validate a Startup Idea Before Building
Validate a startup idea by finding where people already discuss the problem publicly, interviewing 10–15 of them about what they’ve tried and failed at, and only starting to build once you see the same pain point and workaround show up repeatedly.

How to Test Startup Demand Before You Build
Test startup demand by asking for a real commitment, such as a deposit, a sign-up with a credit card, a scheduled call, or a switch away from a current workaround. A "yes" to "would you use this?" is not enough. Commitment, even a small one, is the signal; verbal interest is not.

How to Find Customer Pain Points Before You Build
Find customer pain points by reading places where people already complain unprompted, such as forums, reviews, support tickets, and subreddits. Ask people about specific past moments of frustration rather than their general opinions. A real pain point is one someone is already (imperfectly) trying to solve.

How Many Customer Interviews Do I Need?
Aim for roughly 10–15 early interviews, but stop when new conversations no longer reveal new patterns. Treat this as a better guide than a fixed number.

Do I Need an MVP Before Validation?
No. Validate the problem and demand first through research and interviews, before building an MVP. An MVP tests a specific solution. Building one too early just makes a wrong guess more expensive.

How Do I Test Willingness to Pay?
Ask what they already spend, whether money, time, or a worse tool, to deal with the problem today. Where possible, ask for a small, real (even refundable) pre-payment. Avoid asking "would you pay for this?" directly because people tend to say yes to be agreeable.

Startup Validation
Startup validation is the process of testing whether a problem is real, common, and painful enough that people will act, not just agree, to solve it. Do this before committing time and money to build a solution.

Customer Discovery
Customer discovery is the process of learning directly from potential users, mainly through conversations about their actual behavior, to determine whether the problem you want to solve is real, important, and worth solving.

Problem-Solution Fit
Problem-solution fit is early evidence that your specific solution addresses a real, validated problem. It differs from product-market fit, which concerns broader market adoption at scale.

Willingness to Pay
Willingness to pay is demonstrated through a deposit, a purchase, or current spending on a worse alternative. These actions show that someone will exchange money for a solution, unlike a stated opinion that they might.

Validate a SaaS Idea Before You Build
Validate a SaaS idea by researching whether the workflow problem it solves already shows up as a recurring complaint, interviewing people who currently do that workflow manually or with a worse tool, and confirming they’d switch before building the software.

Validate an AI Startup Idea Before You Build
Validate an AI startup idea the same way as any other: confirm the underlying problem is real and painful before building. AI makes demos cheap and impressive, so it is easy to mistake "this works" for "people need this." Those are different questions.

Validate a Marketplace Idea Before You Build
Validate a marketplace idea by researching the supply side and demand side separately. Confirm sellers or providers have a real reason to list, and buyers have a real, recurring need, before building the platform that connects them.

FirstSight vs Manual Market Research
Manual research gives you full control and depth but takes days of searching before you even start interviewing. FirstSight compresses that research step to minutes and hands you an organized starting point. It doesn’t replace the interviews you still need to run yourself.
