FINTECH 513

FINTECH 513

FINTECH 513 was launched in 2018 by Ricky R. Santiago as a dedicated vehicle for deploying family capital into early-stage fintech companies. The firm emerged as Miami's startup ecosystem began maturing, positioning itself at the intersection of family office permanence and venture-grade sector focus. Rather than diversifying broadly, Santiago concentrated the mandate on a single vertical — financial technology — with the goal of backing founders reshaping banking, payments, and compliance infrastructure. The firm's strategy centers on pre-seed to Series A investments across North America, predominantly in the United States. Ticket sizes range from $250,000 to $1 million, with FINTECH 513 frequently acting as a first-check investor or participating alongside established early-stage syndicates. The portfolio spans sub-sectors including enterprise SaaS for financial institutions, embedded finance infrastructure, and AI-driven compliance tools. Confirmed positions include Finix, the payments-infrastructure company that raised $35 million in Series B funding led by Bain Capital Ventures in 2019 (per Crunchbase News, 2019), and Alloy, the identity-decisioning platform that works with over 600 banks and fintechs. The office participates in both direct equity rounds and selective co-investment vehicles alongside institutional venture funds. FINTECH 513 operates from Miami with a lean internal structure reflective of its concentrated mandate. Santiago leads all investment decisions, drawing on a network of fintech operators and venture partners for deal sourcing and diligence. In March 2023, the firm joined a $4.2 million seed round for Rain, a crypto-native payroll and earned-wage-access platform, alongside investors including Coinbase Ventures and Lightspeed Venture Partners (per Business Insider, March 2023). This deal typifies the office's posture — early entry into regulated fintech infrastructure plays where institutional co-investors validate the thesis. The firm maintains no separate philanthropic foundation or real-asset arm, keeping the entire allocation liquid and directed toward financial technology startups. What distinguishes FINTECH 513 is its unbundled single-family office model — a structure that rejects multi-asset diversification in favor of a single-sector, stage-constrained venture mandate normally associated with specialized micro-funds. Unlike family offices that allocate to external managers, Santiago runs a direct-investment practice where every position reflects an internal fintech thesis. The succession structure remains founder-single-manager, with no publicly disclosed plan for professional management transition. This governance model creates a high-conviction, concentrated portfolio but also key-person risk that institutional co-investors typically underwrite when evaluating the firm's follow-on capacity.
