About Us




Until 2004, 21CT focused exclusively on research and development work for the federal government, largely under Small Business Innovation Research projects, or partnerships with large defense contractors. 

Our work had a singular purpose: how to use smart algorithms to find patterns of suspicious activity in massive volumes of data in order to find terrorist activity and suspicious behavior.  That purpose continues today with our groundbreaking work using the same methodology to detect fraud, waste and abuse in state Medicaid programs.

Irene Williams joined 21CT in 2005 to help the company transform its research and development activities into a product company.  She became CEO in 2008 and today is 21CT’s majority owner.  


Defense & Intelligence

21CT commercialized our work into products for the U.S. Intelligence Community’s urgent and classified counter-terrorism investigations.  This product became 21CT’s proprietary platform and application framework, which included several patents and copyrights, that applied to virtually any domain that has impossibly large data stores containing sensitive information about people, places and things, where the relationships are hidden or unknown. 

21CT has served over 50 federal government customers, either directly or through subcontracting relationships with federal defense contractors, including the Air Force, the Army, Navy, Marines, SOCOM, JIEDDO, SPAWAR, ICE, DARPA and organizations that we are contractually bound not to disclose.  In addition, 21CT has served state government and multiple Fortune 1000 companies protecting sensitive computer networks and critical infrastructure from cyber attacks.


Medicaid Program Integrity

In 2011 the Texas Health and Human Services Commission, Office of Inspector General (HHSC-OIG) approached 21CT in search of a different solution to recognize patterns of fraud within various data sources for Medicaid Program Integrity, and we formally entered MPI in 2012.  

Our software solution, now in its fourth generation, Torch, combined with our investigative unit, Torch Team, has resulted in findings that include hundreds of millions of dollars in suspicious Medicaid payments in multiple health care domains for states to investigate and ultimately act upon. 

Our work to identify fraud, waste and abuse in Medicaid managed care data resulted in our proprietary Universal Claims Model (UCM), a groundbreaking solution, which allows for apples-to-apples metrics computation and analytic leveragability of a variety of health care data including fee-for-service, managed care encounters, or claims.  

Child Protection

21CT applied its analytics solution in a 2014 pilot program to help the Texas Department of Family Protective Services (DFPS) better identify at-risk children.  The findings, which exceeded expectations, included previously unknown case history.
