Our History
Founded in 2003 as DNA2.0, ATUM has built on its DNA design and synthesis expertise to develop an integrated pipeline of solutions for the research community.
With a reverence for the interplay between science, technology and nature, ATUM’s unique and proprietary engineering platform is based on Design of Experiment (DoE), empirical testing and machine learning. The result is the precise engineering of commercially relevant properties in genes, vectors, proteins and cell lines.
ATUM emphasizes customer service as a critical measure of success. We aim to be a resource and research partner for scientists, to enable accurate and innovative delivery of specific, immediately useful solutions. Customers value the individual scientist-to-scientist support they receive from ATUM’s technical sales and support staff, as well as the speed, accuracy, and flexibility with which products and services are delivered. ATUM’s freely downloadable software tool Gene Designer and the online DNA ATLAS, give you the DNA sequence manipulation and management tools that we use in-house.
ATUM is based in the US, with a global customer base encompassing academia, government and the pharmaceutical, chemical, agricultural and biotechnology industries. ATUM is by far the most published synthetic biology vendor, providing expert support to and collaboration with scientists. The company is privately held and is headquartered in Newark, California.
