Portreeve

Portreeve provides an API service that screens signups, trials, checkouts, and logins to prevent abuse such as trial abuse and AI-driven credit farming. It evaluates each event inline and returns a verdict to allow, review, or block the action, helping businesses protect their funnels and reduce fraudulent activity. The system remembers past judgments to identify repeated abuse across different identities and devices.

Who is it for?

Product and security teams at SaaS companies and online services needing to prevent trial abuse and fraudulent signups

Problem

Trial abuse and AI-driven credit farming cause businesses to lose revenue and trust by allowing fraudulent signups and repeated abuse through burner emails and devices. Existing funnels often lack effective screening at critical points like signup and checkout.

Solution

Portreeve acts as a gatekeeper by screening every event inline before the action is committed, returning clear allow, review, or block decisions with reason codes. It maintains a per-tenant abuse graph linking identities and devices to detect repeated abuse and provides a review queue for manual inspection.
