Liberate Bio

Liberate Bio is a genetic medicine company developing in vivo cell therapies that reach cell populations beyond the liver, the long-standing limit of lipid nanoparticle delivery. Its RAPTOR discovery platform is a scalable in vivo screening system that identifies LNP delivery vehicles which work with existing biology to carry genetic payloads into immune cells in blood, bone marrow, and the spleen. Liberate Bio applies that delivery capability to in vivo CAR-M (chimeric antigen receptor macrophage) programs, reprogramming monocytes and macrophages to eliminate disease-driving cells without ex vivo manipulation, with programs in hematologic oncology and in autoimmune disease via depletion of pathogenic B-cell populations. Founded by Nessan Bermingham, Theresa M. Reineke, and Michael Mitchell, and led by CEO Shawn Davis and CSO Walter Strapps, the company raised $31M from Khosla Ventures in October 2025. It is pre-clinical and publishes no public API or developer surface.

Liberate Bio is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Genetic Medicine, Cell Therapy, and Oncology.

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/liberatebio: open an issue to ask a question, or submit a pull request to add artifacts.
