Infinimmune uses its Complete Human sequencing technology® to capture fully paired heavy‑light antibody sequences from up to 300 million B cells, building the world’s largest database of natural human antibodies. Its Anthrobody® library‑on‑B‑cell platform and GLIMPSE™ AI‑driven language model enable rapid selection, affinity maturation, and developability optimization, delivering fully human therapeutic candidates in as little as eight weeks for biopharma and research partners.

Therapeutic antibody discovery relies on artificial libraries and limited screening throughput, leading to long development timelines and a high risk of missing rare, high‑affinity human antibodies that have already been vetted by natural immune responses.
Infinimmune leverages the natural diversity of human B‑cell repertoires to identify and engineer therapeutic antibodies. Their Complete Human sequencing technology® captures fully paired heavy‑light chain sequences from up to 300 million B cells across hundreds of targets, creating an Anthrobody® library‑on‑B‑cell platform. Using native specificity, cross‑reactivity, and affinity data, they select optimal candidates and further refine them with the GLIMPSE™ antibody language model, which combines in‑silico prediction and wet‑lab validation to improve affinity, potency, and developability. This integrated pipeline can progress from discovery to lead generation in as little as 8 weeks, delivering fully human antibodies that have already been stress‑tested by evolution.
Primary customers are biopharma companies and research organizations seeking fast, high‑quality human antibody candidates for therapeutic development, particularly in immunology and inflammatory disease areas.
