Does Anyone Actually Want Your Product? How to Know for Sure

"Everyone I talk to says they'd use it." This sentence has killed more startups than bad code. At DemandSonar, we treat hypothetical interest as noise. What matters is observed demand, the digital exhaust of real purchase intent. Here's how to cut through. First, stop asking friends. Start asking the internet. Our platform ingests many signals per idea on average. It doesn't poll people; it observes their behavior. Searches, forum rants, competitor review gaps, YouTube comments. The "Wants and Pains" algorithm clusters these into unmet needs. One founder was convinced her "meditation app for teenagers" was a winner. Conversations with parents were glowing. But the platform returned a Demand Score of 28. Why? Teens weren't searching for it; they were using general apps. Transactional intent: 8%. Reddit discussions: near zero. She pivoted to a focus tool for students instead, Demand Score 74. Saved 18 months. Hard proof isn't emotional. It's a number. If your Demand Score is below 62, listen. If it's above, you've got permission to build. But don't trust conversation. Trust the billions of data points DemandSonar processes monthly. [Get your real demand number →]
