Bringing to the investment industry real and sustainable solutions to your Compliance and Investment Performance needs has been our history and will continue under the Athos name.


At Athos, we take pride in bringing to the industry a much needed skill set to improve firms, managers and investors alike in all things performance. Our clients’ needs are of the utmost importance to us and we work together with them to provide them the servicing they need.

We are passionate about Compliance and Investment Performance and have dedicated ourselves to this field. Athos brings clarity and understanding to clients who desperately need it to help them better manage their assets and their operations.
