Current Position
Marcos Viriato is Chief Executive Officer and co-founder of Parfin, a digital-asset infrastructure business. His current role is identified in the Point Zero Forum’s 2026 speaker profile. Brazil is the primary professional market used here because Parfin’s institutional work and operating presence are strongly connected to the country. The business also has a London presence; this geographic classification does not imply citizenship.
Background & Biography
Viriato previously held a managing-director and partner role at BTG Pactual. His responsibilities covered operations and technology across investment-banking activities in several markets. He subsequently co-founded Parfin, which was established in 2019. That background links financial-sector operating experience with the design of blockchain infrastructure.
Notable Contributions
Parfin has developed tools for institutional digital-asset custody, trading, tokenization and management. In March 2026, Viriato authored Rayls’ announcement of participation in Mastercard’s Crypto Partner Program.
Why Katharos.ai Is Following Them
Katharos.ai follows Viriato because his work connects institutional finance with blockchain infrastructure in Brazil and beyond. Privacy, interoperability and operating controls are recurring questions in that connection. His prior banking responsibilities provide context for the institutional focus of the business. Coverage will distinguish documented technical work and partnerships from promotional claims about market leadership.
Areas to Follow
Areas to follow include tokenization infrastructure, cross-border settlement and the interaction between permissioned and public blockchain networks. The implementation of announced Rayls partnerships warrants particular attention. Claims about efficiency or reduced risk need evidence beyond a product announcement. Katharos.ai will track the difference between proposed use cases, pilots and operating services.
Reporting Scope
Coverage focuses on verified professional roles, attributable publications, partner announcements and public institutional reports. Company and team achievements are not attributed to Viriato alone. This profile is not an endorsement or investment recommendation, and Katharos.ai does not independently guarantee the authenticity of every cited source. Roles and source descriptions were checked on 20 October 2026.
