Mosaic General Partnership

Rudy Cline-Thomas is the Founder and Managing Partner driving investment strategy. Publicly, he is the only named principal, and his personal trajectory — from an NBA internship to Leeds United co-ownership — reflects the firm's central thesis of blending culture with capital. The firm does not disclose an investment committee structure.

Mastry positions itself as a 'cultural interpreter to capital markets,' which translates in practice to sourcing through deep sports, media, and technology networks. Its acquisition of Athletes First in 2024 embeds the firm directly into NFL talent representation, creating a proprietary pipeline for athlete-backed venture opportunities. The firm also leverages relationships with institutional investors and family capital.

It is a private equity-style asset manager with three distinct investment platforms — venture capital, sports and media, and real estate — operating under the Mastry brand. The firm does not function as a single family office; it manages alternate assets for a diverse array of external clients including institutional investors, global wealth, and family capital.

Mosaic General Partnership is the legal asset management entity; Mastry is the public-facing operating brand through which all three investment platforms are run. Public communications and portfolio disclosures consistently use the 'Powered By Mastry' branding, making Mosaic General Partnership effectively synonymous with the Mastry platform.

The firm takes active operating roles. Rudy Cline-Thomas is directly involved as a co-owner of Leeds United, and the acquisition of Athletes First signals an intent to influence athlete representation and brand-building, not just hold passive stakes. The purchase of the Premier Lacrosse League also points toward operator-level engagement in sports properties.
