S3 Capital

What S3 Capital does

S3 Capital is a private real estate construction and bridge lender founded in 2013 and headquartered at 535 Madison Avenue, New York. The firm provides institutional-quality first-lien financing to middle-market real estate developers for ground-up construction, conversion, bridge, refinance, and condo inventory projects across residential, multifamily, mixed-use, and select hospitality asset classes in supply-constrained Tier 1 U.S. markets. Loan sizes range from under $1M up to $300M, with the firm having originated over $9.5B across 900+ loans and currently maintaining a portfolio of more than 200 active bridge and construction loans.

The core lending platform is executed through a series of closed-end private real estate credit funds (Fund I matured; Fund II and Fund III active). S3 LB RE Credit Fund III reached a $1.3B hard cap final close in May 2026—comprising $850M discretionary and $465M co-investment commitments—and is structured to support approximately $4.3B in loan origination capacity over a six-year life. The technology and operating model is anchored by an in-house origination-to-asset-management pipeline spanning deal sourcing, underwriting, credit, construction monitoring, asset management, and finance, with investor reporting delivered through Juniper Square.

Revenue is generated through three principal streams: interest income on originated construction and bridge loans, management fees on closed-end fund commitments, and origination/processing/exit fees charged to borrowers. Distribution is relationship-driven via a direct origination team and digital channels ([email protected], dedicated phone line), while LP capital is raised through targeted institutional outreach, the Juniper Square investor portal, and earned media in real estate trade publications. The firm is led by co-founders Joshua Crane and Robert Schwartz, both Wharton alumni, and is operationally linked to Spruce Capital, a related real estate equity platform.
