Tissue-targeted medicines, designed in vivo
Manifold Bio has built the first high-throughput in vivo (HTV) discovery engine—combining massively multiplexed in vivo screening and AI-powered design to create targeted biologics.

In vitro is not in vivo
Even the best AI models can only optimize for the context they are trained on. In vitro assays fail to recapitulate the complexity of living systems, missing key properties like PK and biodistribution.
Design, build, track, learn. All in-vivo.
We combine cutting-edge AI-guided protein design with the ability to directly test these designs in living systems.
Our engine sculpts pharmacokinetics, biodistribution, and other key properties of biologics directly in living systems, solving previously intractable challenges for tissue-specific delivery.
We have invented molecular tracking technologies that massively expand the scale of in vivo measurement of biologics. We don’t simulate biology, we have the wetware to measure it.

Towards an in vivo world model
In the limit, we’re building a predictive model of living systems — one that integrates high-throughput in vivo data to map how biomolecules behave in the complexity of the body. This model empowers rational design of therapeutics by closing the loop between molecule, in vivo biology, and therapeutic outcome.
Targeted medicines spanning tissues and modalities.
Expanding the potential of tissue-targeted medicines across modalities and therapeutic areas through internal development and strategic partnerships.
