About Levve

We have sat on both sides of the table.

Levve grows out of a simple observation: mid-sized companies need climate strategies of consulting quality, but cannot and will not pay consulting fees. We have sold, delivered and internally managed these projects. Now we are automating them.

Who we are

We have lived the daily practice inside established companies.

Climate management done in-house, sold, delivered, and now automated. The market gap lies between data collection and modelling, and that is exactly where our two backgrounds complement each other.

Climate strategy & sales

Independent sustainability consultant, then sustainability officer in a mid-sized company, most recently Senior Consultant at Deloitte Sustainability & Climate with decarbonisation and climate risk projects for mid-sized companies and corporations. He knows the problem as a provider calculating consulting projects and as an in-house officer lacking budget, team and data.

Where we stand

Honest maturity instead of gloss.

Levve is a young company in its pilot phase. What that means in concrete terms:

Both analysis modules run as a working prototype and are tested in feedback cycles with pilot customers; onboarding of the first pilot customers onto the platform starts in December 2026.
An active pilot is running with a European development bank (portfolio analysis using PCAF logic).
Both founders have worked full-time on Levve since July 2026, supported by the EXIST founders’ grant, with a scientific anchor at the University of Cologne.
The Levve word mark has been filed for software, SaaS and consulting since August 2026. Incorporation of the company is in preparation.

Pilot customers benefit from exactly this phase: preferential conditions, a direct line to the founders and real influence on product development. What that means for your company →
