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.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/firstfuel-software: open an issue to ask a question, or submit a pull request to add artifacts.
