Investment platforms
built to develop projects
From the Mestdagh family investment vehicle (JEC) to the successive Duodev funds, each platform reflects a step in Equilis’ growth and learning journey.
They provide the long-term vision, stability and independence required to deliver complex, mixed-use developments across Europe.
2006
JEC INVEST
— The foundation of Equilis’ equity platform
JEC is the founding holding company created at the inception of Equilis by the Mestdagh Family. It stands as the core of the group’s equity structure, ensuring the financial independence and long-term vision required to develop complex real estate projects.
Over time, this initial base has been reinforced through strategic partnerships and the establishment of dedicated investment funds, enabling Equilis to scale its activities while remaining anchored in a stable, family-backed shareholding structure.
2017
DuoDev
— A first partnership in confidence
Created in 2017 as a joint initiative between the Mestdagh and P. Mulliez families, Duodev SA financed the redevelopment of Les Papeteries de Genval in Rixensart (Belgium). This pilot partnership laid the foundation for Equilis’ long-term investment model — combining financial solidity, family entrepreneurship, and the ability to deliver complex mixed-use urban regeneration.

DuoDev 2
— Expanding with sustainable discipline
Following the success of the first partnership, Duodev 2 Scom (Pricav Privée) was created as an Article 8 fund under the SFDR, still backed by the Mestdagh and P. Mulliez families but now open to external investors, including institutional partners and family offices. Managing €120 million in equity, it finances ten projects located in the main European cities where Equilis operates, spanning residential, retail and mixed-use developments. Duodev 2 formalized Equilis’ ESG governance across all operations and confirmed investor confidence in its disciplined, impact-driven development model.
2025
DuoDev 3
— Deepening impact and long-term growth
Backed by the Mestdagh and P. Mulliez families, Duodev 3 SA marks a new phase of evolution, with €170 million in own financial capacity and even more advanced ESG criteria. Building on the foundations and learnings of Duodev 2, this new vehicle reinforces the group’s capacity to develop ambitious projects across its six European markets, embedding sustainability, transparency and long-term value creation into every investment decision.
