In December 2010, an investor group led by Helios agreed the acquisition of a majority equity interest in Interswitch Limited (“Interswitch”), the largest payment processing service provider in Nigeria. Interswitch has been at the forefront of the development and growth of the e-payment sector. The firm offers integrated message broker solutions for financial transactions, e-Commerce and e-billing solutions, telecoms value-added services and payment collections solutions. It also administers Verve, Nigeria's leading debit card scheme. In March 2017, TA Associates acquired a minority interest in Interswitch; Helios remains the majority shareholder.
