High-Level Overview

SyntheticFi is a fintech company offering a low-cost, custodian-agnostic securities-backed lending platform primarily for independent financial advisors (RIAs) and their high-net-worth clients (HNWI). Their platform leverages box spreads on S&P 500 Index Options to provide liquidity at interest rates typically 1% to 3% lower than traditional securities-backed loans, starting as low as SOFR + 0%. This approach eliminates cumbersome paperwork and the need to move assets, enabling clients to access liquidity efficiently while keeping their portfolios intact. SyntheticFi’s solution addresses the high cost and complexity of conventional borrowing, empowering advisors to better serve clients’ short-term financial needs or investment opportunities.

For investment firms, SyntheticFi’s mission centers on empowering financial advisors with institutional-grade liquidity solutions that align with fiduciary duties and client interests. Their investment philosophy emphasizes cost efficiency, transparency, and seamless integration with existing advisor workflows, targeting sectors like wealth management, fintech, and capital markets. By introducing innovative synthetic lending, SyntheticFi positively impacts the startup ecosystem by democratizing access to institutional borrowing tools and fostering fintech innovation around securities-backed lending.

Origin Story

SyntheticFi was founded by professionals with deep backgrounds in institutional trading and family office management, bringing expertise in scalable, institution-tested financial solutions. The idea emerged from recognizing the inefficiencies and high costs in traditional securities-backed lending, particularly for financial advisors and their clients. Early traction came from successfully adapting the institutional box spread options strategy—historically used by large market participants—as a retail-accessible lending mechanism, enabling competitive pricing and streamlined processes. This foundation allowed SyntheticFi to evolve into a trusted partner for advisors seeking fiduciary-aligned, client-driven liquidity solutions.
