CosmoLex was developed in 2012 as a first-of-its-kind cloud-based law practice system. The vision of CosmoLex was simple — build a solution to handle law firm operational needs with a single log-in available in a cloud application. Now trusted by thousands of firms, CosmoLex is the #1 end-to-end legal practice management solution with fully integrated matter management and firm accounting.

We're happily headquartered in West Palm Beach, Florida.
