Most startups don’t fail from lack of marketing—they fail from building something no one wants.
Before you run Facebook ads, hire a growth marketer, or burn cash on CAC experiments, you need one thing: product-market fit. Not guesswork. Not gut instinct. Real, validated market demand.
Here’s how to find it—before you spend a dime.
Step 1: Start With Customer Discovery Interviews
Before you write a line of code, talk to at least 20 potential customers. Not friends. Not “maybe” users. Real prospects with the pain point you’re solving.
Questions to ask:
- What’s your biggest challenge with [problem] right now?
- How are you solving it today?
- What have you tried that didn’t work?
- If a tool could solve this perfectly, what would it do?
Tip: Don’t pitch. Just listen. Your job is to uncover problem/solution alignment, not test your feature list.
Step 2: Build a Smoke Test Landing Page
Now that you’ve heard the pain, frame your solution.
Create a one-page site describing your product as if it already exists. Then track interest—signups, email captures, click-throughs.
Tools to use:
- Carrd, Webflow, or Unbounce for fast builds
- Mailchimp or ConvertKit for email collection
- Google Analytics or Hotjar for engagement heatmaps
Why this works: It simulates go-to-market messaging without needing a live product. If nobody bites, you’ve just saved months of build time.
Keyword tie-in: This is the most overlooked but powerful tactic in SaaS validation.
Step 3: Share in Communities & Slack Groups
Go where your audience hangs out. Reddit. Indie Hackers. Specific subreddits. Facebook groups. Even niche Slack channels.
Post your idea (or landing page) and ask:
“Is this a real problem for you? What’s missing here?”
What you’re testing:
- Do people respond emotionally?
- Do they tag others?
- Do they say: “I’d use this” or “I’ve been looking for this”?
Why it matters: Real product-market fit shows up as excitement—not politeness.
Step 4: Look for Pull, Not Push
You’re getting close when:
- People ask you when it’s launching
- They offer to pay or beta test
- They follow up without being prompted
These are pull signals. When you start getting them organically, you’re in the neighborhood of true demand.
No ads required. No paid growth hacks.
Bonus: Pre-Launch Validation Checklist
Use this to pressure-test your product idea before spending a dollar.
Product-Market Fit Readiness Checklist:
Talked to 15–20 target users with the problem
Created a smoke test landing page
Collected at least 100 unique visitors (via organic sharing or forums)
Got >15% of visitors to take a conversion action (sign up, click CTA)
Received feedback or engagement from strangers (not just friends)
Saw users ask about pricing, availability, or timelines
Identified 2–3 recurring pain points or patterns in responses
Final Word: Growth Starts With Truth
If you skip the validation phase, no amount of ad spend will save you.
But if you get product-market fit right from the start? Every dollar you do spend will scale further, faster, and more predictably.
Don’t launch blind. Start with truth. Start with traction before traffic.
