About Johannes

Data-savvy SMEs often already have a solid data foundation – but the business value remains below potential.

  • Because roles are unclear, KPIs are not linked to steering, or
  • Data and business are not aligned.
I help to change exactly that – as an Independent Data Consultant at the intersection of data, people, and business.

My core offering is a structuredData Organization Assessment(~2 weeks, Fixed Fee): a focused inventory of organization & team setup, KPI & steering system, and data model & reporting – with clear recommendations and a concrete roadmap for the next steps.

I bring 8+ years of experience in Data Leadership, Business Intelligence, and Analytics – from roles at Phrase, FREENOW, Cargonexx, and Lotto24 in the SaaS, Mobility, and E-commerce industries.

**Typical Clients**: digital companies with an initial data foundation that want to generate targeted value from it.
