FirstFuel Software

FirstFuel Software was a business-focused energy analytics SaaS company that used utility meter and building data to profile commercial and industrial customers, helping utilities target energy-efficiency and customer-engagement programs. The company was acquired by Uplight, and the firstfuel.com domain now redirects to uplight.com. It was surfaced as a portfolio company of Battery Ventures and added to the API Evangelist network as a stub. The enrichment pipeline found no active first-party developer surface (no developer, api, or docs subdomains resolve, and no OpenAPI, SDK, or MCP artifacts are published), so this profile remains an identity-only record for a company that no longer operates a standalone API program.

FirstFuel Software is profiled on the APIs.io network. Tagged areas include Company, Energy, Analytics, Utilities, and Energy Efficiency.
