SyntheticFi, a San Francisco-based fintech platform focused on portfolio-backed financing for registered investment advisors, has surpassed $2 billion in regulatory assets under management. The milestone comes alongside the company’s disclosure that it has raised more than $13 million in venture funding since its launch in 2023. Its investor base includes Y Combinator, Social Leverage, NextGen VP, The Compound Capital Fund, and other backers connected to the wealth management industry.
SyntheticFi Expands Across the RIA Market
The company said it now works with more than 300 independent advisory firms across the United States. Those firms collectively represent more than 3,000 advisors, reflecting what SyntheticFi described as roughly threefold growth since the beginning of 2026. The expansion highlights rising demand among wealth managers for more sophisticated financing tools that can be integrated into client planning.
SyntheticFi’s platform is designed to help RIAs evaluate and implement lending strategies that were historically more common among institutional investors. These include box spread financing and synthetic variable prepaid forwards, both of which can be used to access liquidity without immediately selling investment assets. By bringing these strategies into an advisor-facing platform, the company aims to make advanced liabilities planning more accessible to a broader segment of affluent clients.
Addressing Liquidity Needs for Affluent Investors
The company’s growth reflects broader changes in the wealth management market, where advisors are increasingly expected to support clients across both assets and liabilities. As wealth creation has accelerated through public equities, private markets, and concentrated ownership positions, clients often face complex decisions around liquidity, tax exposure, and borrowing. SyntheticFi is positioning itself as a technology provider for advisors who want to address those needs within the broader financial planning relationship.
For many affluent investors, liquidity needs can arise from home purchases, refinancing, tax planning, business transitions, or the desire to manage a concentrated stock position. Traditional lending options may not always align with a client’s investment strategy, particularly when selling assets could trigger taxes or disrupt long-term portfolio goals. SyntheticFi says its solutions can help advisors compare alternatives that may offer lower borrowing costs, tax efficiency, and greater flexibility than conventional financing routes.
Bringing Institutional Strategies to Advisors
Box spreads and variable prepaid forwards have long existed in capital markets, but access has generally been limited by complexity, operational barriers, and institutional requirements. Advisors serving high-net-worth clients have often lacked technology infrastructure to analyze and implement these tools efficiently. SyntheticFi’s model combines software, education, and implementation support to help firms incorporate these strategies into their advisory offering.
Tony Yang, CEO and co-founder of SyntheticFi, said borrowing has historically been treated as separate from wealth management. He noted that this is changing as advisors take a more comprehensive view of clients’ financial lives and help them evaluate decisions beyond portfolio construction. According to Yang, the company’s recent growth points to a clear need for better tools that connect liabilities planning with the rest of the advisory relationship.
Growing Investor and Industry Support
SyntheticFi’s funding from investors across fintech and wealth management suggests confidence in the company’s approach to an underserved part of advisor technology. Its backers include venture firms and industry participants with experience supporting financial platforms that serve advisors and investors. The company’s ability to cross $2 billion in regulatory assets under management within three years of founding adds further momentum to its market position.
The platform currently serves a wide range of advisory firms, from emerging RIAs to larger organizations with established client bases. This breadth indicates that demand for portfolio-backed financing is not limited to one segment of the advisory market. Instead, the company appears to be benefiting from a wider industry shift toward more holistic planning and customized liquidity solutions.
SyntheticFi’s latest milestones point to growing interest in advisor-led lending strategies that can support clients without forcing asset sales. With more than $13 million raised, over $2 billion in regulatory assets under management, and relationships with more than 300 advisory firms, the company has established itself as an emerging player in the RIA technology landscape. As it expands its platform and borrowing products, SyntheticFi is betting that liabilities planning will become a more central part of modern wealth management.
