B2B SaaS for accountants
Validator scores 78/100. Strong pain (manual invoice reconciliation), clear willingness to pay ($200/mo), but crowded market. Recommendation: niche down to one accounting platform integration first.

Try a quick scenario
What to do next
- Talk to 10 target customers in the next 14 days — not friends, real prospects. Ask about the problem, not the solution.
- Build a one-page landing site explaining the offer and run $200 of ads to it. Measure interest with email signups, not opinions.
- Use the Startup Cost Estimator to size the real cost of getting the first 100 customers, not just launching.
- Define a 'kill criteria' upfront: if X doesn't happen by Y date, you stop. Founders who skip this burn years on dead ideas.
- Re-validate quarterly — markets shift faster than your roadmap.

Examples
Consumer subscription box
Scores 42/100. Vague audience, weak unit economics ($35 LTV vs. $42 CAC), low retention risk. Recommendation: fix the LTV/CAC ratio with a higher-priced premium tier before launching.
Marketplace for local services
Scores 61/100. Real demand but classic chicken-and-egg supply problem. Recommendation: pre-seed one city with a manual concierge model before building the platform.

What 'validation' actually means
Validation is not friends saying 'great idea!' — that's social proof, and it's worthless. Validation is evidence that strangers will pay for the solution before you've finished building it. The gold standard is a pre-order, a paid pilot, or a signed letter of intent. Email signups are weaker but useful as an early signal.
Most ideas die because founders confuse interest with intent. 'I would totally use that' becomes 'sorry, I don't have budget right now' the moment you ask for a credit card. Build your validation around a real economic action — even $1 charged is more meaningful than 1,000 'likes'.
The four pillars of a validatable idea
Strong ideas score well on four dimensions: problem severity, audience reachability, willingness to pay, and your unfair advantage. Weak on any one and the idea is hard to validate; weak on two and it's likely a hobby, not a business.
Problem severity: how often does the pain occur and how much does it cost when it does? 'Saves 10 hours a month' is severe; 'nice to have' is not. Audience reachability: can you find 100 of these people without spending $10k? If not, your acquisition cost will eat all your margin. Willingness to pay: have they already paid for an inferior solution? If yes, validation is straightforward. Unfair advantage: why you, why now? Without one, expect a copycat within 12 months.
Cheap validation experiments
You don't need a product to validate demand. The five cheapest experiments in order of signal strength:
1. Concierge MVP: deliver the service manually for 5 paying customers before writing any code. Costs nothing, teaches everything. 2. Smoke-test landing page: $200 of ads to a simple page with an email signup or pre-order. Measures real interest. 3. Customer interviews: 20–30 conversations with target customers about the problem (not the solution). Reveals language and intensity. 4. Wizard of Oz: a fake product that looks automated but is actually you behind the scenes. Stripe and Zapier both started this way. 5. Crowdfunding pre-sale: a Kickstarter or Gumroad pre-order forces real commitment from buyers.
How to set kill criteria upfront
Sunk-cost bias is the silent killer of founders. You spend 6 months building, the metrics are weak, but you've invested too much to walk away — so you spend 12 more. The fix is to write down kill criteria before you start: specific, measurable, time-bound conditions that, if not met, mean you stop.
Good kill criteria look like: 'If I don't have 50 paying customers within 6 months, I shut down.' Or: 'If CAC stays above $400 after the first $5k of ad spend, I pivot the audience.' Bad criteria are vague and emotional ('if it doesn't feel right'). Run the validator quarterly with the same inputs to see whether the score is improving — and trust the output even when it disagrees with your gut.
Frequently asked questions
- Is the verdict reliable?
- It's a structured second opinion, not a guarantee. Use it to expose blind spots, then validate with real customers.
- What if I don't have everything?
- Fill what you can — the more context, the sharper the verdict.
- Will it suggest a pivot?
- Yes — when the score is below 6, it proposes a specific pivot direction.
