What our clients say

“An independent view is important in the negotiating process.”

“Argentus knows precisely which benchmarks matter in the German market and was able to show us exactly which contractual points needed work so that we could get an acceptable result for both sides. This independent view of things was very important to us in the negotiating process. Argentus also helped us to expand the contracts to include crucial clauses that appropriately honed the property management incentive structures. We were so won over that we recently tasked the Argentus team with helping us optimise our facility management structures.”

Abigail Shapiro

Head of Germany, Oxford Properties Management

“With Argentus it wasn’t just about one-off measures. That was important for us.”

“What started as a single project has developed over time into strategic cooperation. Argentus supports us across our portfolio with optimising our properties. It is this comprehensive consulting approach that turns individual measures into a viable real estate strategy.”

“Smart metering is an important component of the energy transition. With the help of the intelligent metering systems, the anticipated economies will significantly reduce the future carbon footprint of our portfolio.”

“The price guarantee for energy supply contracts not only gives owners long-term planning stability, it also saves them resources overall, which we can invest elsewhere for them.”

Dr. Johannes Bidlingmaier

Managing Director, Schmidt & Bethge GmbH

“We were able to cut energy costs while reducing the CO2 emissions of our properties. Cutting greenhouse gas emissions is an area where our sector needs to do more – energy supply is part of that.”

Nikolas Jorzick

Managing Director, HAMBURG TEAM Investment Management

“A good blend of empathy and necessary persistence.”

“In day-to-day business, time is often in short supply, and an outside perspective often brings improvements for existing processes and structures. To enable our staff to concentrate fully on our core business and our tenants, we turned to Argentus for support.”

Julia Siegers

Managing Director, IMMOFINANZ Deutschland

“Monitoring operating costs is one of the primary tasks of property management today. We are delighted that together with Westbridge we have been able to achieve such a sustainable and satisfying outcome for our tenants and for us.”

Sustainability that crosses national borders

“Argentus not only contributes valuable real estate expertise, it does so in an international context. That is particularly important for a company with structures that span several countries. Coordination and interfaces across Europe with the Argentus team run seamlessly.”

Carsten Stork

Head of Unit Institutional Asset Management

“Switching to green electricity is important to us, especially for reasons of environmental protection, and is part of our global sustainability strategy. We did an advance screening of the whole services market in Germany and then opted for Westbridge because of their international set-up and their outstanding track record. Our very complex portfolio is now in professional hands.”


Senior Strategic Buyer, Union Investment Real Estate

“Our clear goal is to introduce common ESG sector standards”

“HANSAINVEST Real Assets stands for sustainable investment in the real estate and infrastructure sector. The fact that ESG topics are in Argentus’s DNA makes the team an ideal partner for us. What we appreciate about Argentus is the communication between equals. You can tell that the consultants are from the real estate sector themselves, and Argentus’s hands-on mentality constantly gives us new impetus for developing our own ESG performance.”

Argentus is a comprehensive sustainability manager in a complex field where you would otherwise need several advisors.”

“There is still too little concrete action in the sector”
