Conenergy AG

What Conenergy AG does

Conenergy AG is an unlisted public limited company (Aktiengesellschaft) headquartered in Essen, Germany, that has operated in the energy industry for over 25 years. Founded as an energy consulting firm, the company underwent a strategic transformation in late 2022, divesting its consulting subsidiary (con|energy consult GmbH, sold to Tagueri AG in December 2022) and its trade media business (ener|gate, sold to dfv Mediengruppe in July 2022) to refocus as an investment holding company targeting startups advancing the energy and mobility transition. Since 2015, Conenergy has made direct investments in more than 20 startups from Germany and the USA, plus indirect investments via fund vehicles including the €50M Vireo Ventures Fund (committed November 2022). Portfolio companies span renewable hydrogen (The Yellow SiC Group), AI-driven industrial energy management (encentive), e-mobility software (IO-Dynamics), Morocco-UK power transmission (Xlinks, in partnership with GE Vernova), and electric fleet management (ZeroMission).

The company's product and platform portfolio centers on four pillars. First, the E-world energy & water trade fair, co-organized with Messe Essen since 2001, which set 2024 records with 923 exhibitors from 30 nations and ~30,000 visitors from 72 nations, supported by companion digital events (E-world Kick-off, E-world Web Sessions, E-world Career Forum). Second, the E-world Community digital networking platform launched in February 2021, which uses intelligent matchmaking algorithms to connect energy industry participants year-round. Third, green|connector GmbH, a wholly-owned subsidiary offering white-label SaaS platforms (green|portal and e-mobility portals) to ~14 German municipal utilities and automotive dealers including the Emil Frey Gruppe and Tölke + Fischer Gruppe, with partner The Mobility House providing dropshipping logistics for wallboxes and accessories. Fourth, con|energy akademie, providing certified professional education (Energy Sales Manager, Energy Economist) with corporate clients including GASAG AG (50 sales employees trained). Co-development partnerships include endios GmbH (co-creating the endios one Smart City platform) and SpinLab - The HHL Accelerator (sponsor since 2018).

Conenergy's business model blends transaction-fee revenue from trade fair organization (exhibition space, sponsorship, conference fees), recurring SaaS subscription revenue from green|connector's white-label platforms, professional services revenue from con|energy akademie training programs, and longer-horizon investment returns from its venture portfolio. Go-to-market is anchored on the annual E-world event cycle and the company's 25-year network of European energy industry decision-makers, with co-CEOs Dr. Roman Dudenhausen and Dr. Niels Ellwanger leading the strategy. Ownership is concentrated among the Executive Board, private individuals, and employees.
