How to validate a million-dollar business idea in five steps

Executive overview

Most people pick a business idea based on gut feel and skip straight to building. This wastes months on ideas no one wants. The Million Dollar Weekend process gives you a fast, evidence-based filter: find a real problem, size the demand, calculate customer value, estimate the market, then get paying customers before you build anything.

Run all five steps before writing a line of code or spending a dollar.

Finding an idea

• Browse relevant subreddits to spot recurring pain points and popular topics.
• Look at Amazon best-sellers in your category to see what products already have demand.
• Solve your own problem — frustrations you live with are often the best starting points.
• Existing competitors are a signal, not a barrier: if someone is doing it and isn't dominant, there's room.
• COVID-era constraints created durable new habits; look for categories where convenience is still under-served.

Gauging demand (step 2)

• Use Google Trends to check whether the market is growing, declining, or flat.
• SpyFu reveals organic traffic competitors are already capturing.
• Google Keyword Planner shows search volume and cost-per-click — cheap clicks mean untapped demand.
• Facebook Ads audience size estimates the addressable pool of interested buyers.
• Target categories on an upward trend, not peaked or declining ones.

Customer worth (step 3)

• Check Amazon best-seller price ranges to anchor what the market will pay.
• Compare against direct-to-consumer brands in the category for premium pricing signals.
• For the pubic hair trimmer example: Amazon ranges $40–$70; Manscaped charges ~$70 — set that as your baseline.

Total addressable market (step 4)

• TAM = number of potential buyers × average price.
• If TAM exceeds $1M, you have a million-dollar idea worth pursuing.
• Example: 2M Facebook-reachable buyers × $70 = $140M gross market; capturing 5% = $7M opportunity.
• Same effort goes into any business — choose the one with the biggest upside.

Validating with real customers (step 5)

• Do not build anything before getting a paying customer.
• Text friends, post on social, call potential buyers directly — no website needed.
• If someone says yes, then figure out fulfilment.
• The goal of validation is a single confirmed sale, not a polished product.
