Back to original languageAbout Stephanie
eCommerce growth is acash trap**: your ad budgets increase, CAC drifts, and profitability atrophies. You're flying blind, navigating between misleading ROAS and tightening cash flow, **without clear direction.
I help founders offast-growing DTC brandsregain control of their financials.
How I Help
1. "Marketing Economics" Diagnosis(3-4 weeks, Shopify only)
Audit of real marketing profitability: True CAC, Contribution Margin 3, how many days your cash is "out" before being recovered, LTV, and customer cohorts.
→ You'll precisely understand **where your eCommerce is making or losing money**.
→ You'll finally **master your cash flow cycle**.
→Clear arbitration matrix: what to fix, stop, or accelerate.A clear decision-making document, usable internally or with your investors.
Deliverables:strategic summary + 3 interactive steering tools designed for independent use after the mission(performance review, growth simulator, cohort analysis with projections).
Diagnosis: €8k to €12k depending on scope.
2. Fractional Chief Growth Officer(long-term mission, by selection)
