REFUSED
Disposable Email Signup Defender
52/130 FLOOR 65
Recorded 2026-06-14 · refused 2026-08-01
THE IDEA, IN FULL
Startups and SaaS founders face malicious signup abuse via disposable emails and multi-account fraud. Need better anti-spam verification for freemium and trial tiers. Existing solutions are expensive or have high false positives.
WHY IT WAS REFUSED
Refused at 52 out of 130. The machine's floor is 65, so this one never reached a shelf. It was scored at intake and never ran the full gauntlet. The intake note reads: "HN Show HN with 2 points, 1 comment. Evergreen pain for SaaS founders. Validated by multiple threads on HN about freemium abuse. Chrome extension could integrate with signup forms to detect disposable emails in real-time."
