About Gauthier

Most e-commerce businesses invest heavily in acquisition without ever working on retention.

Result: a repurchase rate below 10% and total dependence on Ads.

With Qoubra, I intervene in the customer lifecycle to make your growth profitable.
My measured results: repurchase rate increased from 8% to 23%, LTV up 35%, email revenue representing 30-40% of turnover.

My approach (R.A.C.E. Method): Retention first, Acquisition next, Conversion, then Expansion. We fix what's leaking before turning on the tap.

My concrete interventions: complete retention audit, Klaviyo setup (flows + campaigns), RFM segmentation, post-purchase journey optimization, loyalty strategy, data piloting (CAC, LTV, cohorts).

Stack: Shopify, Klaviyo, Google Analytics 4, Meta Ads.

Over 20 brands supported. €1M in revenue generated for our clients.

  • LumiBe
    Founder of LumiBe
    E-COMMERCE
    March 2024 - June 2025 (1 year and 3 months)
    Paris, France
    I co-founded LumiBe, a French brand of organic cosmetics and skincare devices, designed to support women aged 35 to 65 in their anti-aging routine. We built a universe centered on customer relationships, with a high-end and human experience. Through a comprehensive e-commerce strategy (branding, acquisition, loyalty), LumiBe achieved a score of 4.6/5 on Trustpilot from 154 customer reviews.

    Building on this experience, my partner and I decided to put LumiBe on hold to fully dedicate ourselves to our digital marketing agency specializing in e-commerce, with a clear positioning: improving customer relationships to maximize lifetime value. We now support ambitious brands that want to build lasting customer loyalty, engagement, and conversion.
