Claros Analytics began within Windsor Strategy Partners (WSP), a leading actuarial consulting firm, with the original development of Actuarial Advisor for use in their consulting practice. As word got out that WSP had a new and better rating manual, underwriters and stop-loss carriers approached WSP to license Actuarial Advisor.

WSP soon realized that benefits consultants and advisors could also derive tremendous value by having robust tools with which they could credibly model changes to plan design, and Actuarial Assistant was developed on the foundation of Actuarial Advisor.

Shortly thereafter development began on additional consulting applications to usefully evaluate the risk-reward dynamics of stop-loss structures (Risk Decision Support) and the projection of claims and development of budget rates (Experience and Migration Predicitive).

In 2014 the needs of the software operation were outgrowing its station as a side project of the consulting team. As a result, Windsor Strategy Solutions, was formed as a separate division within WSP; staff were assigned, and hired, to bring the necessary focus to the software development, sales, and client support. In 2015 Windsor Strategy Solutions, LLC was set up as a separate company from WSP.
