Founded by serial entrepreneur Sherry Vaswani in 2015, Xalient provides managed IT services for clients such as Kellogg’s, Avis and WPP. Its growth has been fuelled by increased demand for cyber security and networking technology. The London-based company generates about half its revenues in America, where it has a base in Chicago. It also has operational centres in Leeds, Romania and India. Vaswani previously set up managed services provider Worldstone, which was acquired by telecoms group JT for an undisclosed sum in 2012.
