What Argentus does
Argentus operates as a private, Germany-based energy and sustainability advisory firm (legal entity Westbridge Advisory GmbH) serving the real estate industry across the DACH region, Poland, Switzerland, and the UK. Its service portfolio spans five integrated lines: E-Mobilität (e-mobility infrastructure), Energieeinkauf und nachhaltige Energieversorgung (energy procurement and sustainable energy supply), Smart-Metering & Sub-Metering, Photovoltaik (photovoltaic integration), and Green Building consulting — bundled and marketed as a single point of contact for portfolio-level sustainability and energy management. The company operates a proprietary mobile application, the Westbridge Zähler App, which supports meter reading and energy data monitoring for clients.
The firm runs a consultative B2B enterprise sales motion targeting property managers, real estate asset managers, REITs, and housing associations. Engagements are bespoke and structured around portfolio size and scope, combining advisory services with implementation support — a positioning repeatedly emphasized in named client testimonials. Revenue mechanics follow a professional services model with project-based and retainer engagements; no public pricing is disclosed. Geographic reach is delivered through offices in Frankfurt, Hamburg, Warsaw, Zurich, and London, with industry positioning reinforced through ZIA, ULI, and vdiv (Premium Partner) memberships.
Named enterprise clients include Becker & Kries, HANSAINVEST Real Assets, HAMBORNER REIT AG, noctua real estate GmbH, IMMOFINANZ Deutschland, Mieter- und Bauverein Karlsruhe, Nieder-Ramstädter Diakonie, and Moayedi Investments, spanning property management, asset management, and adjacent social-services verticals. Distribution is direct enterprise field sales only, supplemented by a customer portal (portal.westbridge-advisory.com) for post-sale client access, with no marketplace, reseller, or self-serve channels. Technology partnerships with agradblue and EKB GmbH extend the energy value chain beyond purely in-house capabilities.
