An evolution in cell line engineering.

64x Bio is transforming the future of cell and gene therapy manufacturing with high throughput discovery and design of enhanced cell lines for next-generation biomanufacturing and therapeutics.

Who We Are

64x Bio is building a platform that radically increases the speed and scale of mammalian cell line discovery. Using novel high throughput genome engineering and screening technologies in a design loop with computational tools, we are developing new ways of generating highly optimized and otherwise unattainable cell lines for the manufacturing of viral vectors, with a specific focus on those used for cell and gene therapies.


Our team includes world renowned scientists and experts in genome engineering and gene therapy from Harvard Medical School, Yale and the Wyss Institute at Harvard University.

Our platform technology enables pharmaceutical and biotechnology companies to bring cell and gene therapies to patients more effectively, providing purpose-built genetically engineered cell lines that increase the efficiency of viral vector production, improve manufacturing capacity and reduce manufacturing cost.
