90% of startups fail, and the #1 reason is building something nobody wants. Validation helps you avoid this fate by testing assumptions before investing significant time and money.

The Validation Mindset. Your idea is a hypothesis, not a fact. Your job is to prove or disprove it quickly. Be prepared to pivot based on what you learn. Seek disconfirming evidence, not just validation.

Method 1: Customer Discovery Interviews. Talk to 20-50 potential customers. Ask about their problems, not your solution. Use open-ended questions: 'Tell me about the last time you experienced X.' Never pitch during discovery interviews.

Method 2: Landing Page Test. Create a simple landing page describing your solution. Drive traffic with small ad spend ($200-500). Measure signup rates and engagement. A 5%+ signup rate suggests strong interest.

Method 3: Concierge MVP. Manually deliver your service before automating. This 'Wizard of Oz' approach tests demand with minimal development. Learn exactly what customers need before building.

Method 4: Pre-sell or Crowdfund. Ask customers to pay before you build. Successful pre-sales prove real demand. Platforms like Kickstarter or simple Stripe checkout work well.

Method 5: Competitor Analysis. Study existing solutions. If competitors exist, that validates market demand. Identify gaps in their offerings that you can fill.

Method 6: Build a Rapid MVP. Create the simplest version that solves the core problem. Launch to a small audience and measure engagement. Use tools like Bubble or Webflow for no-code prototypes, or hire SpeedMVPs for a 2-3 week professional MVP.

Validation Metrics That Matter. Signup/conversion rates, willingness to pay, user engagement frequency, referral rates, and qualitative feedback intensity. Trust actions over words—what people do matters more than what they say.
