Concurrent Real Time, Inc.

On May 15, 2017, Battery Ventures acquired the Real-Time business segment of Concurrent Computer Corporation.

The transaction created a new, independent operating business named Concurrent Real-Time, Inc.

Except for some web-site links and an upcoming domain name change, we expect there will be no changes to Real-Time business operations and no effect on our existing customer base. We will remain dedicated to continued product innovation, and our customers will continue to receive the same high quality support and professional service.
