Kronos Bio was a clinical-stage biopharmaceutical company in the life-sciences sector, backed by GV, working on cancer therapeutics. It surfaced in the API Evangelist network as a GV portfolio lead. The company operates no public API, developer portal, SDK, or technical documentation surface. A live probe on 2026-07-19 found that kronosbio.com no longer hosts a corporate website: the apex and www hosts both return a GoDaddy domain-parking lander that answers HTTP 200 for every path, and the ir, docs, api, and developer subdomains do not resolve at all. No GitHub organization or public repositories were found. This profile is retained as a network record of a company with no API surface rather than as an active API provider.
