About Castalia systems


With years of experience in supporting Military, Intelligence, and Federal clients’ needs worldwide, Castalia Systems is based in Tampa, Florida just outside MacDill Airforce base, home to many significant organizations such as US Special Operations Command and US Central Command. With offices and employees in multiple states and countries, this small business has a large reach and diversified offerings.


Founded by Lindsey Britt and Zachary Mann, Castalia
Systems was created to address the challenging
problems within the Defense and Intelligence Industry.
Having worked for larger companies, the founders
wanted to create a smaller company that operated in a
pleasant, enjoyable, and agile manner. The goal was to
create a company that focused on its people, treating
them like family, while providing top tier solutions to
their clients with honesty and trustworthiness. In 2011, Castalia Systems, an Economically Disadvantaged Woman Owned Small Business (EDWOSB) was born.
