About Arthur

CentralSupélec engineer and former COO of a SaaS company specializing in data, I work where analytics meets business strategy — to help management better understand their performance, structure their data, and make better decisions, faster.

With 12 years of experience at the intersection of data, operations, and product, I have supported dozens of e-commerce and SaaS companies — from €1M to over €1Bn in revenue — in analyzing their performance and identifying their true growth levers.

**What sets me apart**: I don't start with tools, I start with the business. Too many companies have largely underutilized data — unclear KPIs, overly complex reporting, time-consuming manual analyses, non-actionable insights. My role is to reverse this: make data readable, useful, and directly connected to decisions.



**My missions include**:

- Performance analysis and identification of growth levers: acquisition, cohorts / LTV / segmentation, margins, product performance, cross-sell
- Definition of relevant KPIs for your business and reporting structure
- Data exploration and dashboard creation (SQL, Power BI, Tableau, Qlikview)
- Automation of data flows and reporting processes (dbt, Fivetran, n8n, Zapier)
- Structuring analytics teams and improving data workflows

**Sectors**: E-commerce · SaaS · Industry · Retail · Supply Chain


Available for assignments in Lyon or remotely, on a one-off or regular basis — with a preference for projects where data can have a real and measurable business impact.

    Development of an internal web tool to help this SME optimize the management of its global machine fleet.
