Data & Product
Lead & Operator
Reliable numbers, strong teams, clear processes.
I build data and product teams and make sure management, finance and marketing decide on the same, reliable numbers. As a fractional lead who leads teams, or as a fractional operator who builds and runs things myself. Also interim or on a project basis. In data and analytics since 2012, including Zalando and asgoodasnew, freelancing since 2023.

What I do
Three areas that complement each other. You can book each one on its own or combine them.

How we work together
Depending on what you need right now.
Fractional lead
Leadership for a fixed share of the week or month, e.g. as head of data: team, goals, roadmap and stakeholders. For companies that need leadership but not (yet) a full-time position.
Fractional operator
I run things myself: data warehouse, reporting, tracking and the processes behind them. For companies without their own data team, or as reinforcement until the team is in place.
Interim
Bridge a vacancy, keep the team stable, continue the roadmap and hand over cleanly to the successor.
Project
A clearly defined undertaking such as a data warehouse, a reporting or a tracking setup. There are fixed packages to get started.
Entry packages
Fixed entry points for martech & tracking. All prices net plus VAT.

What I stand for
Three values from my leadership credo, which I have consciously lived since my MBA.
Integrity
I say what I think and do what I say. Even when the numbers are uncomfortable.
Authenticity
I lead as who I am: approachable, honest about limits and genuinely interested in the people on the team.
Purpose
Teams achieve more when they know why. I translate company goals into goals the team helps to shape.
