Bright

Bright is Mexico's leading residential and commercial solar energy provider, founded in 2014 (Y Combinator W15) by Jonah Greenberger. Often described as "Sunrun for the developing world," Bright combines financing and software to let homeowners and businesses adopt rooftop solar and battery energy storage (BESS) at no upfront cost. The company operates a marketplace connecting a network of local installers, distributors, and retail promoters with customers, and offers financing models such as solar PPAs and leasing schemes. Bright's public web presence is a Wix-hosted marketing site (thinkbright.mx) covering its industrial, commercial, and home solutions, success cases, and 24/7 energy monitoring technology. It exposes an agent-facing surface via an llms.txt and a hosted Wix Site MCP endpoint, but publishes no first-party developer/REST API.

Bright is profiled on the APIs.io network. Tagged areas include Company, Solar Energy, Renewable Energy, Energy Storage, and FinTech.

Bright’s developer surface includes support and 9 more developer resources.
