Link Cell Therapies

Link Cell Therapies is a South San Francisco clinical-stage cell therapy company founded by Stanford investigators Robbie Majzner and Crystal Mackall in partnership with Samsara BioCapital, working on the development of safe and effective CAR T agents for patients with solid tumors. The company's logic-gate technology produces AND-gate CAR T cells that require co-expression of two cancer targets before driving cell cytotoxicity, giving greater tumor specificity than existing logic-gate approaches and aiming to avoid off-tumor toxicity. Alongside additional platforms under development, Link is advancing therapeutic programs across solid tumors and certain hematologic cancers, including a dual-targeting AND-gated CAR program (LNK001) directed at clear cell renal cell carcinoma, and in January 2026 entered a strategic collaboration with Johnson & Johnson to develop logic-gate LINK CAR T therapies. Link Cell Therapies publishes no public API, developer portal, or machine-readable interface; this profile captures company identity and probed public-surface posture only.

Link Cell Therapies is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Cell Therapy, and CAR-T.

Link Cell Therapies’ developer surface includes product news and 11 more developer resources.

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/link-cell-therapies: open an issue to ask a question, or submit a pull request to add artifacts.
