Willow Wealth Inc. (formerly Yieldstreet) is a U.S. alternative investment platform and fintech firm that provides access to private market investment opportunities across multiple asset classes. The platform enables individual investors—including both accredited and (for specific products) non-accredited investors—to invest in alternative assets such as real estate, private credit, private equity, legal finance, art, structured notes, and other private market offerings. Its mission is to broaden investor access to private markets typically available only to institutions.

Founded in 2015 and headquartered in New York, New York, Willow Wealth operates an online investment marketplace that includes individual direct deals, diversified funds, and managed portfolios. Its offerings are aimed at building a diversified private market portfolio, with products such as the Alternative Income Fund and Willow 360 Managed Portfolios that provide varying risk-return profiles within private assets.

While the platform curates investment opportunities and offers diversified funds, it is primarily a marketplace and investment intermediary rather than a traditional asset sponsor owning the underlying assets. The firm continues to evolve its product suite to serve both investors who select individual alternative investments and those who prefer more automated or diversified private market exposure.
