Understanding Market Demand
Why Positive Feedback Doesn't Mean People Will Buy—And How to Find Real Buyers

"Everyone I talked to loved the idea!"
This is one of the most dangerous sentences in entrepreneurship. It suggests validation when none exists. It creates false confidence, leading to wasted time and money and eventual disappointment when the business launches to silence.
The problem isn't that people lied. Most people are genuinely trying to be encouraging. The problem is that interest and demand are fundamentally different things, and confusing them is one of the most common—and costly—mistakes founders make.
This article explains the critical distinction between interest and demand, why most founders mistake one for the other, and how to design tests that reveal genuine buying intent before you commit resources to building something.
Defining the Difference
What Interest Looks Like
Interest is verbal enthusiasm without commitment. It's what people express when an idea sounds appealing in the abstract, but they haven't seriously considered whether they would actually use it or pay for it.
Interest sounds like:
"That's a really cool idea!"
"I could definitely see myself using that."
"That would be so helpful!"
"Let me know when you launch—I'd love to try it."
"This is exactly what people need!"
"You should definitely do this."
These statements feel validating. They're positive, supportive, and encouraging. But they require nothing from the speaker. No money changes hands. No time is committed. No inconvenience is accepted. Interest is free.
What Demand Looks Like
Demand is demonstrated willingness to give up something of value—usually money, but sometimes time, convenience, or social capital—in exchange for your solution.
Demand shows up as:
"I'll buy one right now if you have it."
"Here's my credit card—charge me when it's ready."
"Can I pre-order? I need this before [specific date]."
"I'm currently paying $X for [alternative]—yours is better."
"Let me introduce you to [decision-maker] at my company."
"I'll commit three hours next week to help you test this."
These statements involve sacrifice. They require the person to give up money, time, reputation, or convenience. Demand is costly—and that cost is what makes it meaningful.
The Critical Distinction
The difference between interest and demand is the difference between:
Theory and practice: Liking an idea versus actually using it
Intention and action: Planning to buy versus actually buying
Possibility and probability: Could use it versus will use it
Polite and honest: Being nice versus revealing true priorities
Businesses succeed when demand exists, not when interest exists. You cannot build a company on enthusiasm that evaporates the moment money is requested.
Why People Express Interest Without Demand
Understanding why people express interest helps you recognize it—and avoid being misled by it.
Reason 1: Social Politeness
Most people don't want to hurt your feelings or discourage you. When you're excited about an idea and ask for feedback, the default social response is encouragement.
This is especially true when:
The person is a friend or family member
You're clearly passionate about the idea
They perceive you as vulnerable or seeking validation
Saying "no" feels uncomfortable
People are conditioned to be supportive. They say "that's great!" the same way they'd say "congratulations" at an engagement announcement—as a social courtesy, not a market assessment.
Reason 2: Hypothetical Thinking
When you describe an idea, people evaluate it abstractly. They imagine a perfect version without considering real-world constraints like:
Price
Switching costs
Time to implement
Learning curve
Compatibility with existing systems
Whether they actually need it right now
In the abstract, many things sound appealing. "A service that organizes your closet" sounds nice. But when you consider the cost, the hassle of letting someone into your home, and the time required, it suddenly becomes less attractive.
Hypothetical interest evaporates when confronted with practical reality.
Reason 3: Solution Looking for a Problem
Sometimes people express interest because your idea sounds clever or innovative—not because they're actively experiencing the problem you're solving.
They might say:
"That's smart—I never thought of that"
"Interesting approach to solving that"
"I can see how that would be useful"
These responses praise your creativity, not the solution's value to them. They're admiring the idea intellectually without a personal sense of urgency.
Reason 4: Future-State Optimism
People overestimate their future behavior. They imagine a better version of themselves who:
Exercises regularly
Cooks healthy meals
Keeps detailed budgets
Learns new skills consistently
Maintains perfect organization
When you describe a product that helps with these aspirations, people mentally place themselves in that future state. "Yes, I would use that!" really means "The person I hope to become would use that."
But aspirational interest doesn't translate to actual behavior change.
Reason 5: Low-Stakes Conversation
When there's no immediate call to action, people respond casually. Saying "I'd use that" costs nothing when there's no expectation of follow-through.
The same person who enthusiastically says "Great idea!" in conversation might:
Ignore your launch email
Do not visit your website
Abandon their cart when they see the price
Choose a competitor
Decide they don't need it after all
Interest expressed in low-stakes conversation rarely survives high-stakes decision-making.
The Cost of Mistaking Interest for Demand
Founders who mistake interest for demand make predictable, expensive mistakes.
Mistake 1: Building Before Validating
Scenario: You talk to 20 people. All of them say your meal prep delivery service is a great idea. Encouraged, you invest $15,000 in a commercial kitchen lease, equipment, and marketing.
Launch day: Zero orders. You send emails. No response. You post on social media: three likes, no purchases.
The problem: Those 20 people liked the idea in theory. But when faced with $60/week for meals, they chose to continue cooking at home, order takeout, or eat what they were already eating.
Mistake 2: Overestimating Market Size
Scenario: You survey 100 people. Seventy say they'd use your service. You calculate: "70% interest rate × 10,000 people in my target market = 7,000 potential customers!"
Reality: Of those 70 interested people, perhaps five actually buy. Your real conversion rate isn't 70%—it's 5%.
The problem: Interest is not a reliable predictor of purchase behavior. Using interest percentages to project revenue creates wildly optimistic—and wrong—forecasts.
Mistake 3: Ignoring Price Sensitivity
Scenario: Everyone loves your handcrafted furniture. They say it's beautiful, unique, and exactly what people want. You price pieces at $2,500.
Launch day: Lots of compliments. Zero sales. People say it's "too expensive" or "not in my budget right now."
The problem: When you requested feedback, you didn't mention the price. People assumed something affordable. Their interest was conditional on a price point you never tested.
Mistake 4: Misreading Encouragement as Endorsement
Scenario: Friends and family tell you to "definitely do this" and "you'll be so successful." You interpret this as validation.
Reality: They're supporting you personally, not evaluating your business model.
The problem: People who love you want you to be happy and successful. Their encouragement reflects their feelings about you, not their assessment of market opportunity.
How to Test for Real Demand
The only reliable way to distinguish interest from demand is to design tests that require commitment. Here's how.
Method 1: Ask for Money
Money is the clearest signal of demand. When someone gives you money, they're making a real commitment.
Pre-Orders
How it works: Offer your product or service for pre-order before building it. Accept payment now in exchange for delivery later.
Example - Handmade Furniture:
Create mockups or detailed descriptions
Set a pre-order price (perhaps 10% discount)
Specify delivery timeline (e.g., 8 weeks)
Offer full refunds if not satisfied
What you learn:
If 50 people say they're interested but zero pre-orders, you have interest without demand
If 10 people pre-order, you've validated actual willingness to pay
Deposits
How it works: Request a small deposit (10-25% of full price) to reserve a spot or secure your service.
Example - Personal Training Studio:
"Opening in 60 days"
"First 20 members pay $50 deposit, get 15% off monthly rate"
"If we don't open, full refund"
What you learn: Deposits separate serious prospects from casual interest. If people won't commit $50, they won't commit $150/month.
Crowdfunding
How it works: Launch a Kickstarter or Indiegogo campaign. Set a funding goal. Deliver only if the goal is met.
Example - Specialty Coffee Roastery:
Goal: $10,000 for equipment
Rewards: Coffee subscriptions, bags of coffee, exclusive blends
30-day campaign
What you learn: If you can't raise $10,000 from people who love the idea, scaling to hundreds of customers will be difficult.
Method 2: Sell Before You Build
You don't need a finished product to test demand. You can validate willingness to buy using minimal versions or manual delivery.
Manual Delivery (Concierge MVP)
How it works: Deliver your service manually before automating or scaling. Charge full price for the manual version.
Example - Meal Prep Delivery:
Cook meals in your home kitchen
Deliver personally to the first 10 customers
Charge the price you intend to charge at scale
What you learn: If people won't pay for the manual version, they won't pay for the automated version. You validate both demand and price before investing in infrastructure.
Landing Page Test
How it works: Create a simple website describing your product. Drive traffic. Measure how many people try to buy (even though you can't fulfill them yet).
Example - E-commerce Home Decor:
Build a one-page website with product photos and descriptions
List prices clearly
Add "Buy Now" button leading to email signup: "Pre-order now, ships in 4 weeks"
Run small Facebook/Instagram ads ($200-500)
What you learn: Conversion rate from visitor to attempted purchase. If 1,000 visitors produce zero purchase attempts, demand is weak. If 50 people try to buy, you've validated demand.
Method 3: Ask for Time Commitment
When money isn't practical to request early, ask for time. Time is valuable, and people guard it. Genuine interest shows up as time commitment.
Pilot Programs
How it works: Offer free or discounted access in exchange for feedback and time investment.
Example - Fitness Coaching Service:
"Free 4-week coaching program for first 10 participants"
Requires 3x/week workouts, weekly check-ins, before/after photos
Must complete feedback survey
What you learn: If people won't commit time when it's free, they definitely won't pay. If 8 of 10 complete the program and rave about results, you have validated demand.
Waiting Lists With Conditions
How it works: Create a waiting list, but require meaningful action to join.
Example - Boutique Opening:
"Join VIP list for exclusive preview event"
Requires: phone number, style preferences survey (10 questions), referral to 3 friends
What you learn: Easy signups (just email) attract casual interest. Signup requiring effort attracts genuine interest. If 200 people express interest but only 15 complete the survey, your real audience is 15, not 200.
Method 4: Watch Behavior, Not Words
The most reliable signal of demand is what people already do, not what they say they'll do.
Observe Current Solutions
Question to ask: "What are you doing right now to solve this problem?"
Strong demand signals:
"I'm paying $X for [competitor], but it doesn't quite work."
"I've tried three different solutions—none are right."
"I built a manual system because nothing exists."
Weak demand signals:
"I don't really do anything about it."
"It's not a big enough problem to address."
"I've thought about solving it, but never got around to it."
If people aren't actively trying to solve the problem now—even with imperfect solutions—they likely won't pay you to solve it.
Track Engagement Depth
Deep engagement indicates genuine interest:
Asking detailed questions about pricing, features, and timeline
Comparing your solution to specific alternatives
Discussing implementation challenges
Introducing you to decision-makers or partners
Following up multiple times
Surface engagement ("that's cool!") is interest. Deep engagement is in demand.
Questions That Reveal Demand
The questions you ask determine the quality of information you receive. Here are questions designed to uncover demand, not collect polite encouragement.
Questions About Current Behavior
"Walk me through the last time you experienced this problem. What did you do?"
"What solutions have you already tried?"
"What are you currently paying for [related solution]?"
"How much time do you spend dealing with this problem weekly?"
"Why hasn't this been solved yet for you?"
Questions About Urgency
"If this problem disappeared tomorrow, what would change for you?"
"When was the last time this problem cost you money, time, or opportunity?"
"On a scale of 1-10, how painful is this problem right now?"
"What triggers you to look for a solution?"
Questions About Budget
"What's your budget for solving this?"
"If I offered this at $X, would that be worth it to you?" (State real price)
"What would make this a no-brainer purchase for you?"
"At what price does this become too expensive?"
Questions About Decision-Making
"Who else would need to approve this purchase?"
"What would prevent you from buying this next week?"
"What information do you need before making a decision?"
"If I launched tomorrow, would you buy?" (Ask for commitment, not opinion)
The Critical Question
After your conversation, ask directly:
"Can I send you a pre-order link this week?"
This single question more effectively distinguishes between interest and demand than any other. Genuine prospects say yes. Polite interest finds excuses.
Red Flags: Signs You're Seeing Interest, Not Demand
Red Flag 1: Vague Enthusiasm
Responses like "That's awesome!" or "Great idea!" without specific questions or concerns.
Genuine buyers ask about pricing, delivery, features, and compatibility. They're solving a problem, not cheerleading.
Red Flag 2: Future Tense Language
"I would use that" or "I could see myself buying that."
The future tense is hypothetical. Demand exists in the present: "I need this now" or "When can I get it?"
Red Flag 3: No Follow-Up
People say they're interested but don't respond to your launch email, don't visit your website, or ghost when you follow up.
Demand creates urgency. Interested people become unreachable. Buyers follow up.
Red Flag 4: Price Avoidance
When you mention price, people change the subject, get uncomfortable, or say "we'll see."
Genuine buyers openly discuss budget constraints: "That's more than I expected, but I can see the value," or "Can we negotiate?"
Red Flag 5: Conditional Interest
"I'd buy if..." followed by unrealistic conditions:
"...if it was half the price"
"...if it had 20 more features"
"...if I had more time/money/resources"
These conditions are often rationalizations. The person doesn't want it—they're being polite.
Red Flag 6: Only Friends and Family Show Interest
If your warmest supporters are all people who know you personally, you haven't found market demand—you've discovered personal loyalty.
Conclusion: Build Businesses on Evidence, Not Enthusiasm
Interest feels good. It's encouraging, validating, and energizing. But interest is not a business model.
Demand is uncomfortable. It requires you to ask for commitment, risk rejection, and accept the possibility that your idea may not have a market. But demand is what builds businesses.
The difference between interest and demand is the difference between:
Words and actions
Hypothetical and actual
Free and costly
Politeness and honesty
Before you invest significant resources in building your business, design tests that require commitment and ask for money. Ask for time. Watch behavior rather than listen to words.
If ten people express interest but zero commit when tested, you don't have demand. If two people commit out of ten, you've found genuine buyers—and that's a far better foundation than a hundred enthusiastic well-wishers.
Build your business on evidence of demand, not the illusion of interest. The distinction will determine whether you build something people actually buy—or something they merely compliment.
