Vauban

What Vauban does

Vauban Infrastructure Partners is a Paris-headquartered, privately-held long-term infrastructure asset manager founded in 2019. The firm invests in essential infrastructure assets that provide foundational services to populations, with a stated focus on sustainable development. Its core activity is acquiring, managing, and operating infrastructure portfolios on behalf of institutional investors and government entities through a managed services revenue model with quote-based institutional pricing.

The company's portfolio spans two principal verticals: district energy systems and digital infrastructure. In the district energy vertical, Vauban owns and operates Detroit Thermal (acquired December 2021 from Basalt Infrastructure Partners and DCO Energy), comprising eight district cooling and heating systems across six U.S. states in the Northeast and Michigan. In the digital infrastructure vertical, the firm operates through its dedicated subsidiary Vauban Infra Fibre, which acquired Towerlink France (urban edge data centers) from Cellnex France with the transaction completing in February 2026. The firm also expanded into Austrian digital infrastructure via the August 2024 acquisition of Cellnex Austria.

Vauban's go-to-market is enterprise field sales targeting institutional investors through bilateral mandates rather than commercial channels. Operational execution is delivered through strategic partnerships with specialized operators — most notably DCO Energy for U.S. district energy facilities. The firm is led by CEO and Founding Partner Gwenola Chambon, supported by a lean team of 11-50 employees. Geographic footprint encompasses France (headquarters and digital infrastructure), the United States (Northeast and Michigan district energy), Austria (telecom towers), and Norway (Boreal Norge acquisition), positioning Vauban as a multi-jurisdictional European infrastructure platform with selective U.S. exposure.
