In his LinkedIn profile, Rajagopalan described himself as a "free man".
He also mentioned that he was employed with Infosys from August 2014 to September 2017, a duration of three years and two months.
It was widely anticipated that Rajagopalan would quit after Sikka put down his papers.
Sikka had brought some of his former SAP colleagues to Infosys to help him implement his new initiatives. One among them was Rajagopalan, who was brought in in October 2014.
Rajagopalan headed Design Thinking, a creative and user-centred approach to problem solving, and was helping the company implement it.
He also helped put together a large-scale design thinking training session for all Infosys employees at Mysuru and other development centres.
In its statement, Infosys said, "The company doesn't comment on exits or appointments other than those of key management personnel."
He was the vice-president of new products at SAP and a former colleague of Sikka.
Catering to Sikka's aim to build technology innovation and get more clients under its fold, Bashir had made 12 start-up investments.
Bashir had joined Infosys in March 2015, primarily to identify and invest in early-stage companies doing cutting-edge work in areas including artificial intelligence, machine learning, big data, cloud and analytics.
