From startups to enterprises, customers trust Rupt.

Alexis Dupont

"Without Rupt, it was impossible to detect account sharers with factual data. Once we added Rupt, we realized we were missing $1M+ ARR and decided to dig into it."

Alexis Dupont

Product Principal, Agorapulse

Adam Siegel

"What we thought would be a real friction point with our existing customers, we saw them go, 'oh my God, why haven't you done this sooner?' They saw it as a feature, not friction."

Adam Siegel

VP of Product Growth, Crexi

Danielle Dyess

"We saw about 4% of account sharers convert immediately after implementing Rupt, which was fantastic."

Principal Product Manager, Sketchy

Andy Romano

"Our first line of defense was to start paying attention to user signals on our own. However, we quickly realized that it was more than a full-time job to accurately identify account sharers."

"Growth rate doubled after implementing Rupt's repeat sign up detection. This improved the platform's stability and availability and reduced our OpenAI credits usage."
