NRGYS, the Nantes-based specialist in energy and environmental performance, welcomes Sodero as a shareholder as part of its development plan.

NRGYS, a key player in energy performance

Founded in 2005 by Patrice Normand, NRGYS has, over the years, established itself as a benchmark in building energy engineering. With more than 100 employees, the company supports real estate stakeholders in the design, management, and optimization of sustainable, energy-efficient, and comfortable buildings. Its expertise is structured around five core business lines: audits and studies, design and project management, owner’s engineering support, energy performance monitoring, and consulting.

NRGYS works on both new construction and renovation projects, with strong experience in multi-family residential housing, commercial buildings, and public facilities. The company has developed a distinctive sustainable approach, integrating bio-based materials and innovative solutions to reduce carbon footprints.

A pioneer in the digitalization of services, NRGYS offers its clients a comprehensive ecosystem of digital tools, including RE2020 and renovation pre-studies, collaborative platforms, user assistance, connected energy monitoring solutions, and the Housing Information Logbook (CIL). This strategy places the company at the forefront of environmental and technological challenges.

Sodero, a strategic partner to support growth

The entry of Sodero, a private equity firm based in Western France, marks a key milestone in NRGYS’s development. A proximity investor committed to supporting regional companies, Sodero backs impact-driven businesses and supports their leaders in transformation projects. Through its Sodero Équilibre fund, dedicated to companies creating environmental and societal value, Sodero provides NRGYS with financial and strategic support, leveraging its expertise and strong regional roots.

This minority investment gives NRGYS access to financial and strategic backing, while enabling it to accelerate its strategy—particularly through external growth projects—to strengthen its position in the fast-growing energy renovation market, driven by new regulations, rising energy costs, and regional decarbonization ambitions.

“We were convinced by the strength of the project and by the natural alignment between NRGYS’s business and our sustainable investment strategy. This investment reflects our desire to commit alongside ambitious, impact-driven companies focused on the challenges of tomorrow.”
Matthieu Simon, Executive Director, Sodero Équilibre
“The context in which NRGYS operates perfectly matches our positioning: supporting local, innovative, and responsible SMEs in structuring their capital and governance. Sodero quickly stood out in a competitive process that attracted interest from both regional and national investors. Its local presence, strong understanding of the business, and prudent approach—particularly regarding leverage—set it apart.”
Simon Morin, Partner, PAX Corporate Finance
“Our meeting with Sodero quickly confirmed a shared vision for the project and the future of NRGYS. This partnership will enable us to continue our development on a larger scale, deliver even more services and innovation to our clients, and rise to the environmental and societal challenges ahead.”
Patrice Normand, Chairman, NRGYS
Opening the company’s capital to employees: extending a culture of sharing

In line with its history and values, NRGYS is opening its capital to its employees. This new step strengthens the company’s momentum by reaffirming the importance of collective commitment and reflects the desire to share value creation with those who contribute every day to its development, while fostering long-term engagement.

A growing company rooted in its regions

Headquartered in Nantes, NRGYS relies on a strong regional footprint, with offices in Paris, Bordeaux, Rennes, Lorient, and Tours. The company opened a new office in Lyon in August 2025, confirming its ambition to strengthen proximity with local stakeholders and deepen its regional presence.
