Proteinea

Proteinea builds a protein-engineering platform focused on next-generation antibodies. It specializes in rational engineering of antibody Fc domains to rewire immune function via “fit-to-function” Fc design, with goals including context-specific immune tuning, enhanced half-life, and targeted biodistribution. The company describes proprietary design frameworks that combine AI-driven prediction with therapeutic insight. It also emphasizes designing modular Fc scaffolds “with translation in mind,” integrating considerations such as manufacturability, stability, pharmacokinetics, and delivery into the design process, and using lean experimental workflows to validate Fc designs and bridge computational outputs to biological reality using minimal experimental data.

Beyond Fc design, Proteinea highlights “Ankh,” a protein language model it is developing and improving. It also describes multi-parameter optimization work showing integration of Ankh and other proprietary models to improve complex proteins across multiple parameters such as stability and solubility.
