64x Bio

64x Bio is a bioengineering company in Brisbane, California, founded in 2018 by scientists out of Harvard Medical School and the Wyss Institute to rebuild the manufacturing foundation for cell and gene therapies. Its VectorSelect platform pairs massively parallelized, barcoded genome-scale pooled screens with computational mining of CellMap, a proprietary atlas linking genetic and metabolic pathway data to production phenotypes, to engineer high-yield producer cell lines. Commercial products are the AAV APEX Suite for adeno-associated virus production across serotypes and scales, the LV APEX Suite for lentiviral vectors used in CAR-T programs, and a Biologics Suite for antibodies and protein therapeutics still in development. The business is delivered through licensing and partnership agreements with therapeutics developers and manufacturers rather than as software: CellMap and the screening stack are internal research infrastructure, and 64x Bio publishes no developer program, public API, SDK or machine-readable contract of any kind.

64x Bio is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Synthetic Biology, Gene Therapy, and Cell and Gene Therapy.

64x Bio’s developer surface includes engineering blog and 9 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/64x-bio: open an issue to ask a question, or submit a pull request to add artifacts.
