Shalom Lamm’s Blueprint for Startup Validation: How to Test Your Idea Before Wasting Time or Money
Coming up with a startup idea is exciting—maybe even intoxicating. But before you start building that app, sourcing suppliers, or spending on marketing, there’s one essential question you need to answer:
Does anyone actually want what you’re offering?
Too many entrepreneurs skip this step and end up pouring months (and thousands of dollars) into ideas that were flawed from the start. That’s why seasoned entrepreneur Shalom Lamm is a strong advocate for validation first, building second.
With a career that spans multiple successful ventures—from real estate to tech startups—Lamm has seen firsthand what happens when founders leap before they look. “It’s not enough to believe in your idea,” he says. “You need evidence that other people believe in it, too—enough to pay for it.”
In this guide, Shalom Lamm shares his tried-and-tested strategies for validating a startup idea—saving you time, money, and unnecessary stress.
1. Start With a Real Problem—Not Just a Cool Idea
Lamm emphasizes that the foundation of any successful business is solving a real, painful problem.
“Too often, entrepreneurs fall in love with a solution before identifying the problem,” he says. “Flip the script. Focus on the pain point first. If the problem is real and painful enough, people will pay for a solution.”
Questions to Ask:
- Who experiences this problem?
- How often does it occur?
- What is the cost (time, money, energy) of the problem remaining unsolved?
Tip from Shalom Lamm: Talk to at least 20 potential customers about the specific issue. Ask them how they currently solve it and what frustrates them most.
2. Validate Demand Before You Build Anything
Many founders think they need a finished product to validate demand. Lamm disagrees.
“You don’t need a prototype or a website to validate an idea,” he explains. “You need a clear explanation of the problem, your solution, and a way to gauge interest.”
This is where minimum viable testing comes in. Instead of building a product, you build a landing page or run a simple ad campaign to test your hypothesis.
Examples:
- Launch a landing page that describes your product and includes a signup form.
- Create a mockup or explainer video that simulates how the product works.
- Run Facebook or Google ads targeting your ideal customer and track clicks or conversions.
If people are willing to give their email—or even better, pre-order—you’re onto something.
3. Pre-Sell Your Product or Service
Shalom Lamm often tells new entrepreneurs: “If no one’s willing to pay for your idea before it exists, they’re probably not going to pay for it afterward.”
Pre-selling is a powerful validation technique that does two things:
- Proves market demand
- Generates revenue to fund product development
Platforms like Gumroad, Kickstarter, or even a simple Stripe integration can help you test willingness to pay before you invest heavily in development.
Lamm’s Rule: “Get your first 10 paying customers before you hire a developer or lease an office.”
4. Find and Test Your Ideal Customer Profile
Not every idea has mass-market appeal—and that’s okay. What matters is identifying who your product is for.
Shalom Lamm stresses the importance of testing different customer segments to find the best product-market fit. “Your idea might work incredibly well for solopreneurs but fall flat with enterprise clients. You need to figure that out early.”
Try This:
- Create 2–3 customer personas
- Run ads or emails targeted to each segment
- Measure engagement, signups, and feedback
Let data—not assumptions—tell you who your audience really is.
5. Test Pricing Early
Pricing is one of the most common reasons startups fail. Set it too high and no one buys. Set it too low and you can’t sustain the business.
Shalom Lamm advises testing different pricing models before you fully launch. “You’ll learn a lot about your customer’s perceived value based on what they’re willing to pay.”
Pricing tests to try:
- A/B testing different price points on your landing page
- Offering tiered pricing to gauge preference
- Asking potential customers directly during interviews
And remember: people saying they “would pay” isn’t enough. You want them to actually pay, even if it’s a discounted pre-order.
6. Use No-Code Tools to Build a Quick MVP
Once you’ve validated interest and pricing, it’s time to build a minimal viable product (MVP)—but it doesn’t need to be complex.
“There are so many no-code tools now, there’s no excuse to spend tens of thousands on development right away,” says Lamm.
Useful No-Code Platforms:
- Webflow or Carrd for landing pages
- Bubble or Glide for app prototypes
- Zapier for automation
- Typeform or Google Forms for user feedback
Lamm’s advice? “Build something people can interact with—even if it’s rough. The goal is not perfection. It’s validation.”
7. Get Real Feedback—Not Just Compliments
Friends and family will always tell you your idea is great. But that’s not useful feedback. Shalom Lamm emphasizes seeking honest, unbiased input from real users.
Tips for gathering useful feedback:
- Ask what they dislike, not just what they like
- Watch users interact with your MVP
- Measure whether they return or share your product
And most importantly: listen more than you speak. Good feedback might hurt your ego, but it sharpens your product.
8. Set a “Go or No-Go” Timeline
Validation can drag on forever if you’re not careful. That’s why Lamm recommends setting a clear time or metric-based cutoff.
For example:
- If 100 people visit the landing page and fewer than 5 sign up, it’s a no-go.
- If no one prepays within 30 days, it’s time to pivot.
“Without a deadline, you’ll keep justifying the idea instead of learning from the market,” says Lamm. “Be brutally honest with yourself. Then act.”
Final Thoughts from Shalom Lamm
Launching a startup is risky—but guessing is even riskier. Shalom Lamm’s validation approach flips the process: prove the idea works before you spend months or years building it.
“The goal is to fail early, fail small, and learn fast. Every minute you validate is a minute you’re investing in success—not just survival.”
So before you pour your savings into that app, hire a team, or rent an office, take a step back. Test. Listen. Prove your assumptions.
That’s how smart entrepreneurs win—and that’s how Shalom Lamm built businesses that last.
