Hamburg-based Reneo has established a €600 million capital platform to support the decarbonisation of residential real estate in Germany. The company focuses on modernising inefficient properties to enhance both ecological and economic value.
Strategic Partnership to Scale Investments
Reneo has formed a joint venture with Peakside Capital, an independent real estate investment manager. This collaboration, alongside an existing senior financing agreement with Goldman Sachs, aims to accelerate investment in energy-efficient housing solutions.
“Our approach integrates climate responsibility with investor value creation,” said Lennart Börner, Founder and Co-CEO of Reneo. “By addressing real estate decarbonisation holistically, we unlock opportunities for sustainable development.”
Technology-Driven Asset Management
Founded by Lennart Börner and Alexander Graubner-Müller, Reneo employs around 100 professionals across five locations in Germany. The company combines real estate asset management with proprietary software to standardise and streamline decarbonisation efforts.
The new joint venture will allocate approximately €500 million in debt and equity to enhance energy efficiency in multi-family properties. By applying its data-driven approach, Reneo aims to modernise outdated buildings, lower carbon emissions, and reduce energy costs for tenants.
Additionally, the company seeks to optimise under-utilised spaces, addressing the growing demand for modern housing.
Addressing Market Gaps in Green Investments
Despite strong institutional interest in sustainable real estate, a shortage of suitable assets remains. Over half of Germany’s residential properties have poor energy efficiency ratings (EPC rating E or lower), presenting an opportunity for transformation. Reneo’s initiatives reportedly reduce energy consumption by 30-60%, leading to lower operational costs for both property owners and tenants.
AI-Powered Decarbonisation Strategy
Reneo’s proprietary platform, the Reneo Core System (RCS), leverages machine learning to analyse property data and determine optimal retrofit strategies. It evaluates energy savings potential, renovation costs, available government incentives, and financial returns to guide investment decisions efficiently.
“Our end-to-end solution simplifies the transition to greener buildings while ensuring strong financial returns,” said Co-CEO Alexander Graubner-Müller. “We are committed to scaling our impact with like-minded partners.”
Expanding Real Estate Investments
Since 2020, Reneo has transacted over €500 million in assets. In 2024 alone, the company invested over €200 million, acquiring more than 600 residential units spanning approximately 40,000 square meters in Berlin and Hamburg.
Industry Backing and Strategic Investments
Boris Schran, Partner at Peakside Capital, highlighted the sector’s decarbonisation challenges. “Real estate remains one of the last frontiers in achieving net-zero goals. Reneo’s technology-driven approach provides a scalable solution to address this challenge effectively.”
The initiative also secured €45 million in equity financing from investors including Eurazeo, Lakestar, and Foundamental, as well as family-owned businesses Goldbeck and Bauwens. Angel investors such as Stefan Wiskemann and Fabian & Ferry Heilemann also participated. The Series B round was led by Eurazeo, while Lakestar headed the previous Series A.
Future Expansion Plans
Eurazeo’s partners, Pierre Devillard and Raphael Cattan, emphasised the potential for Reneo’s expansion. “Our investment through the Smart City Fund II aligns with our goal to drive technology-led urban sustainability. We look forward to supporting Reneo’s growth across Europe.”
