Sioni Group is a New York City–based real estate development and investment firm founded by brothers Ray and Jack Yadidi, in partnership with their father. What began as a family venture rooted in fashion has grown into a multigenerational real estate company known for its hands-on leadership, thoughtful design, and forward-thinking approach.

With proud Iranian Jewish roots, the Yadidi family brings a deep sense of tradition, trust, and responsibility to everything they do. Their early success in the apparel industry—where they built a respected women's fashion label known for refined craftsmanship—informs the way they approach real estate today: with a designer’s eye, a builder’s precision, and a founder’s commitment.
At Sioni Group, real estate is personal. Every project is guided by a belief in doing things the right way, with the long term in mind. The company is fully family-operated, with the next generation involved across all divisions—from development and design to leasing and management. This level of personal investment ensures quality, accountability, and care at every stage.
What sets Sioni apart is their unwavering focus on innovation, functionality, and aesthetics. They reject the “cookie-cutter” mindset of traditional development, instead embracing new materials, sustainable building practices, and smart technology to create spaces that feel intentional, efficient, and future-ready. Their goal is not just to build buildings—but to build value, community, and legacy.
