Dimitri Visnadi
Fractional Head of Ecommerce | Founder-led Brands (€500k–€5M)
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 bring their marketing together, from paid ads and email to agencies, customer data, and growth strategy. As brands grow, marketing often gets fragmented. Different people manage different channels, everyone has their own numbers, and founders are left trying to connect the dots. That's where I come in. Less about individual channels or dashboards, more about making everything work together. I've spent 12+ years working across ecommerce, marketing, and data, including projects with brands like Nintendo, Red Bull, and Unilever. I've been independent since 2019. **On GrowthMentor, I can help you with:** ↳ Making sense of your marketing numbers and priorities ↳ Aligning agencies, freelancers, and marketing channels ↳ Understanding customer acquisition, retention, and profitability ↳ Identifying what's holding back growth and what to fix next ↳ Getting a second opinion on your ecommerce strategy Best fit: Ecommerce founders with an established business who want clarity, direction, and fewer moving parts.
