What fjol-digital does

fjol GmbH is a Münster-based sustainability consultancy founded in 2011 as a spin-off from the ZNU (Zentrum für Nachhaltige Unternehmensführung) at the University of Witten/Herdecke. The firm delivers sustainability strategy, ESG reporting (CSRD, VSME), climate accounting and strategy (Corporate and Product Carbon Footprint, SBTi), supply chain due diligence (LkSG, CSDDD, EUDR), EU Taxonomy alignment, and EcoVadis rating improvement to SMEs and large enterprises across more than 20 industries in Germany. Its core methodology is the ZNU-Standard 'Nachhaltiger Wirtschaften' — a holistically integrated, scientifically grounded sustainability management standard that is independently certifiable and holds state recognition (DAkkS) — delivered through a co-educational, modular consulting model that builds internal client capability.

The firm's technology stack centers on the leadity ESG software platform (founded 2019 as fjol-digital GmbH, now leadity GmbH, under common ownership), which supports sustainability strategy, management, and reporting — including CSRD, GRI, and DNK reporting formats — and features an integrated AI function for facilitated report writing. Revenue is generated through bespoke, quote-based professional services engagements under multi-year contracts; no public pricing is disclosed. Customer acquisition is driven by direct enterprise field sales, a free initial consultation booked via Microsoft Bookings, content marketing, event co-hosting (e.g., Westfälischer Klimadialog), and referral from a base that has grown to 100+ customers annually.

fjol and leadity together employ over 80 people as of 2025 (fjol alone grew from 3 founders in 2011 to 20+ by 2023), and the firm is privately held by four partners — Managing Director Dr. Katrin Nitz alongside Drs. Michael Raß, Axel Kölle, and Christian Geßner — with no external institutional investors, venture capital, or private equity ownership.
