Nabla Bio

Nabla Bio is a Cambridge, Massachusetts biotechnology company founded in 2021 as a Harvard spinout, building generative protein design systems for de novo biologics discovery. Its platform is JAM (Joint Atomic Modeling), a multimodal generative model trained on large-scale protein sequence and structure data that takes partial molecular context — a disease target or an epitope — and computationally designs the rest, producing de novo antibodies, VHH-Fc and full-length mAb formats, epitope scaffolds, cytokines, receptor traps and multi-domain multispecifics. The company pairs the model with an integrated wet lab that feeds mammalian, cellular and in vivo measurements back into training, and has published work on de novo design of GPCR-targeting antibodies against CXCR4 and CXCR7. Nabla Bio engages exclusively through pharmaceutical partnership and molecule licensing — with AstraZeneca, Bristol Myers Squibb and Takeda — and does not operate a public developer program, API, SDK or self-serve platform.

Nabla Bio is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Drug Discovery, and Protein Design.

Nabla Bio’s 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.
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/nabla-bio: open an issue to ask a question, or submit a pull request to add artifacts.
