Magellan Investment Partners North America

The sole principal is Leonid Radvinsky, an entrepreneur who built his wealth through digital-payment platforms and affiliate marketing before acquiring OnlyFans in 2018 through Fenix International. Radvinsky founded B4X, a video-chat and e-commerce network, and has a background in software development dating to the early 2000s. His ownership of OnlyFans has generated over $500 million in dividends between 2021 and 2023 (per Financial Times, 2022).

Radvinsky's fortune stems primarily from his majority ownership of Fenix International, the parent company of OnlyFans, a subscription-based content platform. He acquired the company for a reported $100 million in 2018 and subsequently benefited from the platform's explosive growth during the creator-economy boom. Prior to OnlyFans, he founded or controlled several digital-payment and affiliate-marketing businesses, including B4X and MFCXY, Inc.

Magellan Investment Partners North America operates as a single family office managing Leonid Radvinsky's personal capital. There is no public evidence that the firm accepts outside LP commitments or manages third-party money. All known investments appear to be funded through Radvinsky's dividend income from OnlyFans and prior business exits.

The firm's direct-investment activity spans venture capital, growth equity, and select public-market technology positions. Radvinsky has made angel investments in early-stage software companies and participated in later-stage rounds for developer-tool and payments businesses. There is no public record of the office committing to traditional blind-pool fund structures.

Radvinsky operates the Radvinsky Foundation, a separate philanthropic vehicle focused on grants to open-source software projects and technology-education initiatives. The foundation's activities are legally distinct from Magellan's investment operations. No investment capital from the family office flows through the foundation structure, based on available public disclosures.

Magellan and OnlyFans share a common owner in Leonid Radvinsky, but are legally separate entities. Fenix International operates OnlyFans as a UK-based content-platform business, while Magellan Investment Partners North America is a US-domiciled investment vehicle that deploys Radvinsky's personal liquidity from dividends and other sources. The family office does not manage OnlyFans operations.

No co-investment partnerships or club-deal networks have been publicly documented for Magellan. The firm's low public profile and the principal's preference for direct, un-syndicated technology investments suggest limited appetite for GP-led co-investment structures, though the absence of disclosure makes the full posture difficult to assess.
