We use sophisticated technology to run our investment activities, with more than 650 talented developers and engineers pushing its potential. When platforms don’t meet our standards, we build our own.

The entrepreneurial spirit has always been a part of our firm’s culture. (We even created one of the world’s first free email service providers.)

In 2015, we formed Arcesium LLC to make part of our capabilities available to other asset managers. Arcesium is now an independently operated company that provides post-trade technology and services to financial clients, while continuing to support the D. E. Shaw group and its funds.
