description: 'Formation Bio (formerly TrialSpark, rebranded in December 2023) is a
  New York-based, tech-driven, AI-native pharmaceutical company co-founded by Ben Liu
  and Linhao Zhang. Rather than discovering molecules, Formation Bio in-licenses and
  acquires clinical-stage drug assets and runs them through a proprietary, software-
  and AI-driven development engine that compresses clinical planning, trial execution
  and regulatory work. That engine is a suite of internal platforms — Delphi (probability-of-technical-success
  and value modeling), Atlas (clinical-stage asset screening), Forge (autonomous trial
  design and scenario evaluation), Apollo (trial execution, study startup, enrollment
  and closeout), ARK (an AI orchestration layer connecting 80+ internal systems behind
  one governed interface) and a unified Data Platform spanning trial data, real-world
  patient data, literature and standardized ontologies. The company raised a $372M
  Series D led by Andreessen Horowitz with participation from Sanofi, and built Muse,
  an AI patient-recruitment system, with Sanofi and OpenAI. Formation Bio''s technology
  is internal-facing: as of this profile the company publishes no public developer
  portal, API documentation, machine-readable API contract, or client SDKs.'

  note: >-
    Formation Bio publishes no public API. Probed /openapi.json, /openapi.yaml,
    /swagger.json, /v1/openapi.json, /api-docs, /docs, /redoc and /graphql on
    www.formation.bio and app.formation.bio; probed the /.well-known/ namespace
    (security.txt, openid-configuration, oauth-authorization-server, api-catalog,
    ai-plugin.json, agent-card.json, agent.json) on every resolvable host; resolved
    api./developers./docs./status./trust./mcp./muse. subdomains (all NXDOMAIN except
    app., which 404s on every path). The Next.js site answers HTTP 200 with an SPA
    not-found shell for arbitrary root paths, so a 200 there is not evidence of a
    document — every candidate was body-checked and every one was the "Oh no!" shell.
    See well-known/trialspark-well-known.yml for the full probe table.
  no_wellknown_pointer_reason: >-
    well-known/trialspark-well-known.yml records an all-404 result; no WellKnown
    pointer is wired because no well-known document exists.
