Transforming Rare Antibody Discovery to Make Novel Medicines Possible

About Us

Eira Bio harnesses synthetic biology and evolution to make the most challenging discoveries routine. 


We are pioneering the next generation of antibody-based biologics targeting challenging multi-pass membrane proteins to address unmet needs in the treatment of disease.

Our powerful, scalable yeast-based platforms enable the discovery, evolution, and optimization of precision antibodies against complex multi-pass membrane targets, including GPCRs, ion channels, and solute transporters that have historically been inaccessible. Our technology unlocks new therapeutic opportunities for diseases with high unmet need. 

Our Science

Eira Bio is transforming drug discovery and development for challenging multi-pass membrane targets by combining cutting edge synthetic biology and directed-evolution technologies with world-class drug development capabilities.

Synthetic Biology

Synthetic biology circuits enable identification of rare antibodies with high scale, efficiency, and precision.

Directed Evolution

Directed evolution platforms enable affinity maturation without the constraints of a predefined library.

Transformational Therapies

Unique antibodies against high-value targets enable new first and best-in-class therapeutics.
