Score anatomy
One deterministic formula for every opportunity.
The total is 30% demand, 25% explicit pain, 20% momentum, 15% competition gap, and 10% confidence. Saturating curves limit viral outliers and recent evidence decays progressively. It is a prioritization signal, never a market-size claim.
Scores compare evidence inside VentureSift. They do not guarantee demand, revenue, feasibility, or product-market fit.
