TrialGuard Abuse Detection

Detect and block users abusing SaaS trial credits with burner emails

Problem

SaaS founders complain that users create multiple accounts with disposable emails or fake profiles to repeatedly claim trial credits, directly hurting revenue and increasing fraud overhead. Existing options require manual review or heavyweight fraud platforms.

Solution

A lightweight API/SDK that checks disposable email domains, device fingerprints, IP reputation, and payment linkage at signup and trial start, returns a risk score, and supports auto-restriction or a manual review queue; a simple dashboard shows abuse trends.

Users

Indie SaaS founders, growth and risk leads, small SaaS teams

MVP

Real-time disposable email domain detection; device fingerprint and IP risk scoring; risky account list with manual flags; simple API integration docs

Revenue

Usage-based API billing with a free tier; team plan with dashboard and alerts

Why now

AI lowers the cost of bulk signups, trial abuse is rising, yet small SaaS has no dedicated budget; an indie developer can aggregate public data sources into a cost-effective vertical risk tool
