17,908 New Users in 90 Days. Cost per Conversion €0.66.
"Checkgrow scaled our SaaS faster than any agency ever did. Once I saw the system working, I decided to invest in the company too. That says it all."

COO
Qubinets is a cloud infrastructure SaaS platform built for developers and DevOps teams. With growth stalled at 2 signups per day, Checkgrow rebuilt their entire acquisition engine using AI-driven campaigns, analytics integration, and automation. In 90 days, they onboarded over 17,900 new users while reducing CAC by 76%.
Introduction
Qubinets had a strong technical product. What they lacked was velocity.
Despite building a powerful cloud-native SaaS platform, user acquisition was slow and inconsistent. Traffic was not properly qualified. Messaging did not fully resonate with the technical buyer mindset. Conversion rates remained flat.
Growth was not a product issue. It was a system issue.
