The number one reason SaaS products fail is not technical -- it is building something nobody wants. After helping dozens of founders launch SaaS MVPs, I have seen the pattern: the founders who validate first succeed more often. Here is the exact framework I recommend.
The Validation Framework: 4 Stages
Stage 1: Problem Validation (Week 1)
Before you think about solutions, confirm the problem exists and people care enough to pay for a fix.
Action: Talk to 15-20 potential customers.
Find them on LinkedIn, Reddit communities, industry Slack groups, or by cold emailing businesses in your target market. Ask these questions:
- "How do you currently handle [problem]?" -- Understand the current workflow.
- "What is the most frustrating part of this process?" -- Find the pain points.
- "How much time does this take you per week?" -- Quantify the problem.
- "Have you tried any tools to solve this?" -- Understand alternatives.
- "If this problem magically disappeared, what would change for your business?" -- Gauge urgency.
Do NOT: pitch your idea, describe your solution, or ask "would you use X?" People say yes to hypotheticals but do not pay.
Green light to continue: At least 10 out of 15 people describe the same pain point, and at least 5 are actively looking for a solution.
Stage 2: Solution Validation (Week 2)
Now describe your proposed solution and test willingness to pay.
Action: Create a 1-page solution description and share it with your interview subjects.
The description should include:
- What the product does (3 bullet points)
- Who it is for (1 sentence)
- How it differs from alternatives (1-2 sentences)
- Price (be specific: EUR X/month)
Ask: "If this existed today at this price, would you sign up?" Follow up with: "Can I put you on the waitlist?"
Green light: At least 5 people say "yes, I would pay for this" and give you their email.
Stage 3: Demand Validation (Week 3)
Action: Build a landing page and drive traffic.
Create a simple landing page with:
- Clear headline stating the problem you solve
- 3-4 feature descriptions (with mockups if possible)
- Pricing
- Email signup or "Join Waitlist" button
Drive traffic with:
- EUR 200-500 in Google Ads targeting your main keywords
- Posts in relevant communities (Reddit, Indie Hackers, Twitter/X)
- Direct outreach to the people you interviewed
Green light: 3-5% conversion rate on the landing page (visitors to signups). If 100 people visit and 4 sign up, the demand signal is strong.
Stage 4: Revenue Validation (Week 4)
Action: Pre-sell before building.
This is the strongest validation: ask people to pay before the product exists. Offer:
- "Founding member" pricing (50% off the first year)
- Early access with input on features
- Full refund guarantee if you do not deliver in 60 days
Use Stripe or Gumroad to collect payments. Even 3-5 paying customers before writing code is a massive signal.
Green light: At least 3 paying customers (not friends or family).
Red Flags That Mean "Do Not Build"
- "Nice idea" responses with no email signups -- politeness is not validation
- People describe the problem but say "I would just use a spreadsheet" -- low willingness to pay
- Landing page gets traffic but zero signups -- the solution does not resonate
- Everyone wants different features -- no clear core use case
- Only free users, nobody converts on paid plans -- wrong market or wrong pricing
Pricing Validation Tips
Getting the price right is critical. My approach:
- Start higher than you think. It is easier to lower prices than raise them.
- Use value-based pricing: If your tool saves 5 hours/week and their time costs EUR 50/hour, that is EUR 1,000/month in value. Price at 10-20% of value = EUR 100-200/month.
- Offer 3 tiers: Starter (limited), Professional (most features), Enterprise (everything). Most customers pick the middle tier.
- Annual discount: 20% off for annual plans. This improves cash flow and reduces churn.
Validation Without Technical Skills
You do not need to code to validate. Use:
- Carrd or Webflow for the landing page
- Typeform for customer interviews at scale
- Stripe for pre-sales
- Figma for product mockups
- Google Ads for demand testing
Once validated, bring in a developer for the build. I help founders go from validated idea to launched MVP in 4-6 weeks. Book a free consultation to discuss your validated SaaS idea.
