About Reia Natu

Most brands don’t need more traffic — they need Data Science for Customer Acquisition and CX to convert traffic into revenue at lower CAC and better lifetime value.I started as a Data Scientist focused on CX analytics, helping businesses understand their customers better. Over time, I realized that the real game-changer was using data to drive growth, not just measure it.
