Most fintech ideas fail on three patterns: compliance burden, real CAC, and defensibility against incumbents. I scored 571 fintech ideas on Preuve AI. Only 24.9% cleared the 70-point viability threshold. The other 75% had at least one of those three failure modes load-bearing in their plan.

Score 70+ rate  
24.9%  
Of 571 fintech ideas scored on Preuve AI, 24.9% scored 70 or above on the viability check.  
70+ means an idea cleared all six frameworks (TAM, VC scorecard, Lean Canvas, Porter, risk, PMF) with no single dimension dragging it down. By design, most don't reach it.

## How do I validate a fintech idea?

Validate fintech ideas against four checks: regulatory feasibility, unit economics under realistic CAC, defensibility versus incumbents, and a 12-month wedge that does not require a banking license. Of 571 fintech ideas scored on Preuve AI, 24.9% scored 70 or above.

## How fintech ideas die

1. **Compliance burden underestimated**  
   Founders pitch a payments or lending product without budgeting for licensing, audits, and ongoing reporting. The 12-month timeline doubles once a real lawyer reads the spec.

2. **CAC math assumes warm channels**  
   B2C fintech CAC sits between $40 and $150 for an active account. Decks regularly model under $20 because they assume influencer or organic growth that never materializes.

3. **Banking-as-a-service dependency**  
   Stripe, Unit, or a sponsor bank can pull the rug. Ideas without a clear backup provider fail the dependency test inside the Preuve risk framework.

4. **Incumbent feature parity**  
   A solo founder cannot beat Wise on FX or Brex on cards through features alone. Pitches that match incumbent feature lists without a defensible wedge score in the high 40s and stay there.

5. **Trust signal absent**  
   New fintech brands get rejected by users until they show audit reports, charters, or partner logos. Pitches without a credible trust artifact in week one score 10 to 15 points lower on the risk framework.

## If your idea fails the fintech viability check, pivot here

- **Pivot to API-first infrastructure**  
  Sell to fintechs instead of consumers. Compliance and brand trust matter less when the buyer is another regulated entity.

- **Niche down to one regulated vertical**  
  Insurance for freelance designers, lending for restaurant owners. Smaller wedges have lower CAC and clearer evidence loops.

- **Become a workflow tool first**  
  Ship the spreadsheet replacement before the payment rails. Land the audience, then layer regulated products once you have data.

## FAQ

- **How long should fintech validation take?**  
  Six to eight weeks for a thorough pass. Two weeks for landscape research, two for customer interviews, two for an unregulated MVP, and two for compliance scoping with a specialist lawyer. Anything shorter skips the lawyer step, which is where most fintech plans die.

- **What scoring threshold matters for fintech?**  
  A 70+ Preuve AI viability score lines up with ideas that survive compliance review. Below 55, the path to a regulated product is rarely viable without a co-founder who has shipped a fintech before. Between 55 and 70, the wedge usually needs sharpening before the lawyer review.

- **Do I need a banking license to launch?**  
  Not at the prototype stage. Banking-as-a-service partners cover the regulated layer for the first 12 months. Renegotiate or in-house once volume justifies it, and budget for the transition before you hit it. Plans that ignore the BaaS exit cliff score lower than plans that name the date.

- **How big a TAM does fintech need?**  
  Median fintech TAM across the 571 scans is $2 billion. Below $500M, unit economics rarely work because compliance fixed costs dilute margins. Verticals like SMB invoicing, freelance benefits, or expat banking can still meet the bar with a sharper ICP.

- **When should I pivot away from fintech?**  
  If your scan shows compliance burden as the dominant risk and you have no co-founder with regulated experience, pivot toward an unregulated workflow tool that solves an adjacent pain. Land the audience first, layer the rails later once you have evidence and a war chest.
