Greybrook

Co-founder Elias Vamvakas serves as Chairman and CEO, leading the firm's overall investment strategy. Sasha Cucuz, as CEO of Greybrook Securities, oversees the capital-raising and broker-dealer operations. The firm's real estate and private equity teams operate under senior investment professionals who source and manage individual transactions, with deal-level decisions made by the respective asset-class heads alongside Vamvakas.

Greybrook structures each investment as a standalone limited partnership. Investors commit capital to specific, identified development projects or private-equity transactions rather than contributing to a pooled blind-pool fund. This project-by-project architecture gives limited partners visibility into each asset before funding and allows them to build their own portfolios of Greybrook-sponsored deals over time.

Greybrook concentrates its real estate activities in the Greater Toronto Area and South Florida, with a preference for transit-oriented, infill development sites. Private equity investments target growth-stage companies across North America. The firm has maintained a dual-country Canada-US footprint for more than a decade, with South Florida representing its primary US expansion corridor.

Greybrook partners with local real estate developers as a significant minority or joint-venture equity provider, typically entering projects after municipal approvals are advanced. This approach relies on long-term relationships with established operating partners in Toronto and South Florida rather than competitive auctions. The firm targets mid- and high-rise residential projects where its capital accelerates construction timelines and de-risks the developer's balance sheet.

Greybrook Securities Inc. is a regulated exempt-market dealer subsidiary that serves as the firm's in-house capital-raising arm. It is registered with the Ontario Securities Commission and distributes Greybrook-sponsored limited partnership units to accredited Canadian investors. This vertical integration removes reliance on third-party placement agents and allows Greybrook to control its fundraising pipeline directly, a structural attribute uncommon among Canadian real estate investment platforms.

Greybrook typically acts as the co-investment partner rather than soliciting external co-investors for its own deals. In real estate, the firm invests alongside local operating developers who hold the general partner role; in private equity, it leads or co-leads growth rounds. The firm's investor base consists of individual limited partners who invest through Greybrook-sponsored vehicles, with no disclosed practice of inviting third-party institutional capital into its transactions.

Greybrook charges deal-specific management fees and carried interest tied to individual project outcomes rather than a blind-pool's aggregate performance. Because each investment is structured as a standalone partnership, investors incur fees only on the deals they select, and the firm's promote is realized at the asset level — creating a direct link between Greybrook's compensation and the actual construction, lease-up, or operational success of each project.
