Trial Abuse Sentinel

Stop free-trial farming before AI costs burn the founder

Problem

AI SaaS free trials often include costly generation credits, so bad actors register hundreds of accounts to harvest free usage; founders report losing thousands of dollars in a single incident and usually only discover it when the bill arrives, with no idea when it started.

Solution

Connect signup and usage logs, cluster accounts by email, device fingerprint, payment fingerprint and behavior patterns to detect bulk signups and repeat trials, alert in real time when cost thresholds are crossed, and support auto-pause of suspect accounts with a human review queue.

Users

Early-stage AI SaaS founders and indie developers offering free credits

MVP

Signup and usage log ingestion; duplicate email/device/payment clustering; suspect account list with evidence; cost threshold alerts; manual approve or block

Revenue

Subscription by monitored accounts with monthly alert quota; premium tier adds auto-blocking and API

Why now

Agentic tooling makes bulk signups easier while AI trial costs dwarf traditional SaaS, and founders are already complaining publicly, so the need is clear
