You have a SaaS idea. It solves a real problem -- or at least it feels that way. The question is: does anyone want to pay for it?
Most founders answer that question by building for 3 months, spending $5,000 in contractor time or 300 hours of their own, and then launching to silence. Not because they lacked skill. Because they skipped validation.
Here is a 5-step framework you can run in a weekend, before you write a single line of code.
Not potential customers. People who have actively dealt with the problem in the last 30 days.
Search LinkedIn for job titles that would have this pain. Post in a relevant Reddit community ("anyone else struggling with X?"). Check Slack communities in your niche. Ask your own network.
Your goal is not a survey. You want 5 actual conversations -- even 15 minutes each -- where you ask: "How are you handling this right now?" and "What does it cost you, in time or money?"
If you cannot find 5 people with this problem, the market is too small or too hard to reach. Stop here.
Go to G2, Capterra, and Product Hunt. Search your problem category. If you see existing tools, that is good news -- it means the market exists and people are already spending money.
Read the 1-star reviews on competing products. Those are your feature gaps and your positioning.
If there are no competitors at all, that is a red flag, not a green light.
You do not need code for this. Use a simple tool or a static HTML page to describe the problem, your solution, and one call to action: "Join the waitlist" or "Get early access for $X."
Write the page for the 5 people you spoke with in step 1. Name their problem in the headline. Describe the outcome they told you they wanted.
This is not a design exercise. It is a signal test.
Spend $50 on a targeted Google or Meta ad. Or post in the communities where you found your 5 interview candidates. Or DM 100 people who match your target profile on LinkedIn.
Your goal is 50-100 page visits. Measure signups or clicks, not impressions.
If fewer than 5% take action, the page or the idea needs work. If 10% or more do, you have something worth pursuing.
Email the people who signed up. Tell them you are building this and you are offering early access for a one-time price of $X.
If 5 people hand you money -- even $50 each -- for something that does not exist yet, you have validated demand. Refund anyone you cannot deliver to. But willingness to pay is the signal that matters more than any survey answer.
By Sunday night you know three things:
If all three are yes, you are ready to build.
The moment you decide to build, time becomes your biggest cost. Building auth, payments, email, and a database from scratch takes weeks. With Next.js SaaS Boilerplate, those systems are already done -- JWT authentication, Stripe subscriptions, Resend transactional email, Drizzle ORM with Neon DB, a pre-built landing page, and a one-click Vercel deployment pipeline.
You validated in a weekend. You can ship a working MVP in another one.
Once you know people want your product, the only thing standing between you and revenue is build time. A starter kit removes that delay. You go from "validated idea" to "paying customers can sign up" in days instead of months.
Once you are ready to launch, the SaaS launch checklist covers what to verify before you go live -- so nothing slips through between your MVP and your first real customer.
