    Approves of CEO

    I have been working at 21CT full-time (More than 3 years)


    New brand is a true reflection of the strategic growth and potential of 21CT to truly change the world. Analytic technology PLUS people EQUALS results.


    It is a startup, so you must be ready to shift and wear dozens of different hats. Be ready to be uncomfortable at times and welcome new challenges.

    Advice to Management

    Keep focused and listen to what the market is telling you. Although growth is tremendous it is critical that as a company we also focus on growing in the right places.

    I applied online. The process took 4+ weeks. I interviewed at 21CT (Austin, TX).


    The interview process was thorough. I interviewed with four to five employees I would be working closely with. We discussed various topics regarding my background and skill set. It was an overall positive experience.

    Missionary Work in Guatemala - 21CT

    Our CEO, Irene Williams and COO, Robert Williams spent the week of July 13-17, 2015 helping care for 49 abandoned children in Guatemala. Irene's nurturing and tortilla-making skills are putting smiles on many faces. Robert is moving rocks and dirt to build a sand volleyball court for the kids to enjoy.
