What ISI does

ISI Management Consulting GmbH is a German boutique management consulting firm founded in 2005 and headquartered in Düsseldorf. The company is exclusively focused on advisory services for municipal utilities (Stadtwerke) and adjacent organizations in the energy, water, and transport sectors. Its core service lines cover energy and water consulting (including energy policy, grid infrastructure, and water management), transportation consulting (mobility and logistics), and a set of innovation modules spanning digitalization, robotic process automation, and grid/network transformation (including hydrogen core network planning and municipal heat planning under German Energiewende regulation). Technology underpinnings include partnerships for SAP S/4HANA implementation (with consolut.gmbh), RPA tooling for process automation, and the GIPS Statistik web analytics platform developed within a shared industry consortium for Stadtwerke.

The firm operates a project-based, quote-driven professional services model with engagements sold directly to enterprise and public-sector utility decision-makers. Its go-to-market relies on direct sales, referrals, thought-leadership content (158+ blog posts and 35+ expert articles), and presence at major German energy industry events (E-world, IEWE, hydrogen congresses). Distribution is confined to Germany, with a minor international footprint through ESC India (established 2014). ISI is privately held by its Managing Directors (Matthias Niederprüm, MBA, and Mario Dohr) and Partners (Dr. Claudia Werner and Anne Heitmann), with no external institutional investment disclosed. The company is actively operating, recently certified its data protection management system (2025), and celebrated its 20th anniversary in 2025.
