description: >-
  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.
