TrustROI is a software comparison platform that ranks tools by verified return on investment. Unlike review sites (G2, Capterra, Product Hunt), TrustROI requires every listed tool to connect a read-only API key to one of four supported payment gateways — Stripe, Paddle, Dodo Payments, or RevenueCat — so customer counts and retention months are auditable, not self-reported.
TrustROI Score = (Verified Paying Customers × Average Retention Months) / Monthly Price. A higher score means more verified customer value per dollar spent. Scores are recalculated nightly from gateway data.
