How to find a million-dollar SaaS idea using three filters

Executive overview

Most founders pick ideas without doing the math, building for months before discovering no one will pay. Before writing a line of code, validate that your idea can reach $1M ARR at a price point realistic for your market.

Three filters do the work: price-based math to size the customer target, a 10x differentiation test, and a 100-10-1 outreach rule to confirm real demand.

Cheap software doesn't win — 10x better software does.

Step 1: Do the math on price and customer count

• $1M ARR = $83K MRR. That number doesn't change; your price point determines how many customers you need.
• At $9/month: 9,259 paying users required.
• At $29/month: 2,874 users.
• At $99/month: 842 users.
• At $299/month: 279 users.
• At $999/month: 83 users.
• Price determines product quality bar, sales motion, and who can afford to buy.
• No-code tools can support a $9–$29 product; they rarely produce competitive $99+ products.
• Choose your price tier before scoping the product — it defines what you're actually building.

Step 2: Apply the 10x rule

• If no one else is doing your idea, assume smarter people already tried and it failed. Pick a competitive space.
• Identify where the market leader is weak. Build one feature that is 10x better than theirs — not all features, just one.
• Alternatively, go vertical: purpose-build for a specific niche (e.g., a CRM only for used-car salespeople). Less competition, tighter fit, easier to win.
• Do not compete on price. Buyers won't move critical operations to an unknown startup for a lifetime deal — they want better, not cheaper.
• The 10x bar applies to ROI too: a $29/month tool needs to deliver at least $300/month of value for a buyer to justify it without deliberation.

Step 3: Use the 100-10-1 rule to pre-validate

• Talk to 100 people in your ideal customer profile before building.
• Expect roughly 10 to express genuine interest.
• Expect 1 to become a paying customer.
• If zero people show interest after 100 conversations, the idea is wrong — go back to step 1.
• One customer proves the thesis. Repeat: talk to another 100, get another customer, build from there.
• Also use this exercise to sanity-check market size: reaching $1M ARR at $29/month requires 2,874 customers, which means engaging ~28,000 prospects over time. Confirm that pool exists.
• Scale only after unscalable early conversations confirm the product thesis.
