What Sunstone Credit does
Sunstone Credit is a technology-enabled commercial solar lending platform founded in 2022 and headquartered in New York with a co-headquarters in Baltimore. The company provides solar loans to small and medium-sized businesses (SMBs) through a partner-first go-to-market model, working with solar installers, developers, EPCs (engineering, procurement, and construction firms), consultants, and platforms such as EnergySage, Aurora Solar, and Energy Toolbase to embed financing into the sales process. Its product portfolio includes core commercial solar loans ($50,000 to $6 million, 5-20 year terms, 100% financing, no prepayment penalties, UCC-only collateral), the Large Loan Program (up to $30 million), SOL (standalone energy storage loans), the Express Loan for small businesses, and the Green Glove turnkey service. Underlying technology comprises a cloud-based, end-to-end digital loan origination and servicing platform with AI-driven underwriting and credit decisioning, encrypted document management, and partner-facing workflow tools.
The company generates revenue through two primary streams: fixed-percentage loan origination fees charged to developer partners (varying by term and rate) and interest income from originated loans, which are funded through lending partners including Cross River Bank, M&T Bank, Forbright Bank, and DLL rather than held on Sunstone's balance sheet. Customer segments span storage/warehousing, retail, multi-family housing, agriculture, nonprofits and educational institutions, manufacturing, and tenant/landlord scenarios — reflecting a deliberate strategy to serve commercial borrowers historically underserved by traditional financing. Key distribution channels include the partner program (application, approval, participation agreement, training in roughly two weeks), direct-to-borrower via the Green Glove service, and platform integrations that surface loan quotes inside solar sales software.
Sunstone has raised $20 million in a January 2023 Series A led by Greenbacker Capital Management, with participation from Earthshot Ventures, Grotech Ventures, Cross River Digital Ventures, and Forbright Bank. The company acquired ORKA Finance in January 2024, opened its Baltimore co-headquarters in March 2024, surpassed $1 billion in cumulative commercial solar loan applications by September 2025, and has been actively expanding its product line through 2025-2026 with SOL (October 2025), the King Energy retail portfolio program (December 2025), and the Large Loan Program (April 2026). Leadership includes CEO Josh Goldberg (former founder of Astrum Solar and Sunlight Financial), CTO Sumbul Alvi, CFO Scott Muckleroy, Chief Risk Officer Mike D'Andrade, and other executives with backgrounds spanning solar installation, banking, and fintech.
