Mosaic

What Mosaic does

Mosaic was a private fintech platform founded in 2011 and headquartered in Oakland, California, that provided residential solar and home improvement financing to homeowners through a contractor-distributed channel. Its core products comprised the Mosaic Financing API for partner and contractor integration, the Mosaic Portal for contractor onboarding and loan management, the Swiftlink connectivity layer, and the Borrower Loan Servicing Portal that allowed homeowners to view loan information, make payments, and access account details. Loan servicing operations were executed through Solar Servicing LLC (NMLS ID 2744383), with Forbright Bank operating as a banking partner in the servicing ecosystem.

Mosaic monetized originated loans via transaction fees, generating revenue by financing residential solar installations and home improvement projects underwritten through its contractor partner network. Its go-to-market was API-first and B2B2C: Mosaic partnered with solar and home improvement contractors who embedded its financing into their sales workflows, with the Borrower Loan Servicing Portal handling the post-origination lifecycle. Customer segments were homeowners seeking financing for solar or home upgrades and the contractor SMBs who channeled those loans. Notable institutional backing included Warburg Pincus (Series 4 lead in August 2016), Core Innovation Capital, Obvious Ventures, DZ BANK, Green Bank, and the US Department of Energy, with cumulative funding exceeding $289 million across equity and debt.

In 2026, Mosaic filed for Chapter 11 bankruptcy protection as part of an industry wave of roughly 100 U.S. residential solar company failures since 2023, triggered by rising interest rates and the elimination of the federal Residential Clean Energy Credit. U.S. residential solar installed capacity had declined 31% year-over-year in 2024 and an additional 2% in 2025. Mosaic's home improvement financing technology assets were acquired by LendingClub in January 2026 as part of its $500 billion home improvement market entry alongside a partnership with Wisetack, while the CEO Patrick Moore departed for Koalafi and the NuSource Financial subsidiary was divested in November 2025.

Broad incumbents

• SunPower: SunPower is a large residential solar installer that filed for bankruptcy in 2024 alongside Mosaic's collapse; comparable as a vertically integrated solar provider that historically used third-party financing partners like Mosaic.
• Sunnova Energy: Sunnova is a major U.S. residential solar and energy storage provider that also went bankrupt during the same industry downturn; while vertically integrated into installation, its financing activities overlap with Mosaic's lending vertical.
• LightStream (Truist): LightStream is a bank-affiliated online lender offering unsecured home improvement loans to consumers, representing a larger incumbent competitor in the broader home improvement consumer financing category Mosaic targeted.
• Affirm: Affirm is a leading point-of-sale consumer credit platform with broad merchant integration; while not solar-specific, it competes for the same embedded-finance consumer lending wallet and uses comparable API/portal distribution.
• LendingClub: LendingClub acquired Mosaic's home improvement financing technology and is now a direct competitor in the contractor-channel consumer lending space Mosaic pioneered.

Direct peers

• GoodLeap: GoodLeap is one of the largest point-of-sale residential solar and home improvement financing platforms, competing head-to-head with Mosaic in contractor-channel consumer lending for clean energy upgrades.
• Loanpal: Loanpal provides residential solar and home improvement loans through contractor partnerships, with a similar contractor-portal/API distribution model and comparable consumer credit underwriting approach.
• Dividend Finance: Dividend Finance offers solar and energy-efficiency financing to homeowners through installer networks, directly overlapping Mosaic's contractor-channel lending business.
• Sunlight Financial: Sunlight Financial was a residential solar loan originator serving installers and homeowners — a near-identical business model to Mosaic that also experienced distress during the same rate/subsidy headwind cycle.

Emerging players

• Wisetack: Wisetack is a point-of-sale consumer lender for home improvement services and is cited as Mosaic's partner for home improvement financing expansion, making it a directly comparable and now-adjacent competitor in the contractor-channel lending space.
