OxonCapital

Co-founders Juan Sartori and Sergey Glinka lead the firm. Sartori sets strategic direction but his involvement in Uruguayan politics — as a former Senator and presidential candidate — means Glinka likely handles much of the day-to-day portfolio management. The firm has not publicly disclosed the composition of its investment committee or senior team.

Juan Sartori's wealth originates from his chairmanship of Union Group, a Latin American holding company with significant stakes in agribusiness and energy, and from his marriage to Ekaterina Rybolovleva, whose father Dmitry Rybolovlev built a fortune in Russian potash mining. The combination gives the family office a capital base tied to both Latin American operating businesses and Russian industrial wealth (per public record).

OxonCapital operates as a single-family office deploying Juan Sartori's personal capital. There is no public evidence that the firm accepts third-party limited partners or manages funds for external investors. The structure provides a permanent-capital mandate without the fundraising cycles or redemption pressures that constrain typical asset managers.

The firm does both. In venture, OxonCapital writes direct checks into early-stage companies while also committing capital as a limited partner to external VC funds. This dual approach allows the office to source proprietary deal flow while gaining diversified exposure to managers with sector-specific expertise.

On the venture side, OxonCapital focuses on seed and early-stage startups, particularly in enterprise software, fintech, and AI. The firm's public-equity and special-situations activity spans a broader range of stages and sectors, including real estate and energy transition. The combination gives the office exposure across early-stage venture, growth-stage co-investments, and liquid markets.

Sartori's political campaigns in Uruguay — including a 2019 presidential run and ongoing Senate involvement — introduce periods where he is less involved in daily investment decisions. During these windows, the office likely relies more heavily on Sergey Glinka and any senior investment staff. The firm's evergreen capital structure means it does not face pressure to deploy or exit on any predetermined timeline, accommodating these political cycles.

The firm invests across the United States, Latin America, and Europe. Its US venture activity centers on New York and Silicon Valley. Sartori's personal and business networks provide strong sourcing channels in Uruguay, Brazil, and Argentina, while the Rybolovlev family connection creates access to opportunities in Europe and Russia. The office's public-equity book operates globally.
