Dimitri Visnadi
Ecommerce Strategy & Attribution Advisor
Extremely insightful conversation with Dimitri. He was able to open my eyes to many possibilities using data science. Will be having another call soon. Highly recommended. Thanks!
I got 2 great ideas from our call that I could implement right away and feel more confident about our marketing spend. Thanks a lot!
Dimitry shifted my whole perspective on data collection and data analysis. I will be a lot more careful not to jump to conclusions prior to knowing I'm actually tracking all the datapoints that matter. I really enjoyed this call. Thank you very much!
Bio
I help ecommerce founders and growth leads make sense of conflicting numbers across Shopify, GA, and paid channels, so they can decide what actually matters before scaling. This is not about dashboards or tooling. It’s about clarity, attribution logic, and decision-making. I bring 12+ years across ecommerce, marketing, and data, with experience spanning startups, scale-ups, corporates, and Google-partnered consulting.
