Its technology harnessed the existing thermal mass of a building — concrete, drywall, furnishings — by pre-cooling during off-peak hours and coasting through peak demand, effectively operating the building as a multi-megawatt battery for demand response and load shifting without installing dedicated storage hardware. The company raised a reported $7 million venture round and appears in the Battery Ventures list of all portfolio companies. As of a July 2026 review the company has no live corporate web presence: the cleanurbanenergy.com domain no longer serves company content, and no developer portal, API, documentation, or GitHub organization could be located. It is catalogued here as an inactive, non-API-provider company record.' url: https://raw.githubusercontent.com/api-evangelist/clean-urban-energy/refs/heads/main/apis.yml x-type: company x-source: vc-portfolio x-backed-by: - battery-ventures x-tier: stub x-tier-reason: portfolio-lead x-status: inactive x-status-evidence: - 'cleanurbanenergy.com resolves via Cloudflare but serves unrelated third-party content (an academic essay-writing content farm); no MX, SPF or TXT records present' - 'No api.cleanurbanenergy.com host; cleanurbanenergy.net and cleanurbanenergy.io do not resolve' - 'GitHub organization search for cleanurbanenergy / clean-urban-energy returns 0 results' - 'No developer portal, API reference, or documentation found in web search' specificationVersion: '0.20' created: '2026-07-17' modified: '2026-07-20' tags: - Company - Energy - Cleantech - Energy Storage - Thermal Energy Storage - Demand Response - Smart Buildings - Commercial Real Estate - Chicago - Inactive apis: [] common: [] maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io x-enrichment: date: '2026-07-20' status: minimal artifacts_added: 0 pass: local-v1
