Cellarity

Cellarity is a Somerville, Massachusetts based clinical-stage biotechnology company founded in 2017 inside Flagship Labs by Flagship Pioneering, which discovers medicines against the cell as a whole rather than a single molecular target. Its multi-omics, AI-powered platform is trained on tens of millions of single-cell transcriptomes to characterize disease as a shift in cell state and to design small molecules that course-correct that state back toward health. The company has raised roughly $294M across Series A, B and C rounds from Flagship Pioneering, BlackRock, The Baupost Group and Pictet Group, runs an active MASH collaboration with Novo Nordisk, and is advancing CLY-124 — a first-in-class globin-switching oral medicine for sickle cell disease — through a Phase 1 clinical study, alongside myelofibrosis and exploratory hematology programs. Cellarity publishes no product or developer API and runs no developer program; its only anonymously readable machine-readable surface is the WordPress REST API (wp/v2) that serves cellarity.com — news items, the drug-development pipeline, leadership and board profiles, event speakers, case studies, platform videos, media and site search — as JSON. Its scientific software is published as open-source research code in the github.com/Cellarity organization (DrugReflector, DILImap, MolRL), and its technical documentation site at docs.cellarity.com is a private Read the Docs Business instance behind SSO.

Cellarity publishes 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Drug Discovery, Life Sciences, and Artificial Intelligence.

Cellarity’s developer surface includes product news, support, authentication, and 23 more developer resources.

scored 2026-09-25 · rubric v0.23.0
Regulatory Posture applies to this provider. Its tags matched the Health 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.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cellarity: open an issue to ask a question, or submit a pull request to add artifacts.
