Buildscience

BuildScience Inc. (Y Combinator Winter 2015) was a PropTech startup based in Mountain View, California that built an operating-system platform for commercial buildings. Its software let building owners and facility operators deploy customized building-management solutions intended to reduce operational costs while improving tenant satisfaction, and the company reported deploying in a one-million-square-foot Class A office building. As of the 2026 enrichment pass the company appears dormant: the buildscience.com domain no longer serves a live product (the host returns a CloudFront default certificate that does not match the domain and a broken origin), no developer portal, documentation, or public API surface could be located, and the organization's single public GitHub repository was last updated in January 2020. This profile is retained as a verified-identity network record; no API artifacts could be enriched because the provider publishes no live API.

Buildscience is profiled on the APIs.io network. Tagged areas include Company, PropTech, Buildings, Building Management, and Facilities.

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.

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/. This rating is computed from github.com/api-evangelist/buildscience: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
