History

Subex was founded in 1992 by Subash Menon and Alex Puthenchira as a marketing company; the word "Subex" is a portmanteau of the founders' first names.[1] The company then started providing enterprise software services like revenue assurance, fraud detection and network analytics to telecom operators.[2] The company went public in July 1999, and got listed on the Bombay Stock Exchange and National Stock Exchange of India.[3]

In 2006, Subex acquired British firm Azure Solutions for US$140 million in a merger deal and renamed itself as Subex Azure Limited. The acquisition was then the biggest by an Indian IT company.[1] In 2007, the company acquired Syndesis, a Canadian operations support software company, for US$164.5 million.[4] The company's GDR was issued on the London Stock Exchange in March 2007.[5]

Subex's debt rose during the Great Recession due to the foreign currency convertible bonds (FCCBs) issued to fund the acquisitions.[6][7] In 2011, Subex sold the provisioning and activation verticals of Syndesis to Netcracker Technology.[8] In 2012, Menon resigned from the company,[9] and Surjeet Singh was named the new CEO and managing director.[10] By 2016, Subex converted the FCCBs and was reported to have become a debt-free company.[11][12]

In 2018, Vinod Kumar was appointed as the CEO and managing director of Subex.[13] The company then expanded its business operations to the domains of Internet of Things (IoT) security, artificial intelligence and digital trust.[14][15][16] In April 2021, Subex launched an enterprise cloud-native augmented analytics platform named HyperSense.[17][18]

In April 2023, Nisha Dutt was appointed as the CEO of Subex. [19]
