FirstFuel Software, now operating under the Uplight brand, originated as a standalone energy analytics firm before being acquired by Uplight in 2021. The company specializes in providing utility-grade energy efficiency and demand management solutions, targeting both residential and commercial sectors. Its technology platform integrates data analytics with behavioral insights to drive customer engagement in energy savings programs.

Uplight, the parent company, has positioned FirstFuel's capabilities as part of a broader suite aimed at modernizing grid flexibility and electrification efforts. The acquisition was part of Uplight's strategy to consolidate energy software tools under a single umbrella, leveraging FirstFuel's expertise in building energy analytics. Recent SEC filings indicate Uplight's revenue growth, though specific figures for FirstFuel are not disclosed separately.

The company's solutions are now embedded within Uplight's platform, which serves over 50 utilities across North America. Notably, Uplight secured a $100 million investment in 2025 to expand its load flexibility programs, signaling continued focus on integrating FirstFuel's legacy analytics into next-gen energy management tools.
