About Us Sunstone Credit is on a mission to revolutionize commercial solar finance.

Sitting at the intersection of climate, finance and technology, Sunstone is opening the door to a previously underserved segment in the solar industry by offering financing solutions that help businesses save money and reduce their carbon footprint by going solar.

Founded in 2021 by successful serial founders, Sunstone has a strong backing from top VC firms and financial institutions that position our company for explosive growth in 2025 and beyond.  In late 2023, we seized an opportunity to accelerate entry into the residential segment through the acquisition of Sunlight Financial.

We have partners and customers that are diverse, and we are building a team that reflects that. Our team members collaborate and innovate from our HQ in NYC’s Flatiron District and every one of our colleagues shares in Sunstone’s success with meaningful equity ownership.

Climate change is the greatest challenge humanity has ever faced. We are doing our part to stop it. This is not just a job, it’s a mission – true believers only. Come join our team!
