Actis has pumped $50m into the firm. As part of the deal, Actis’s head of South Asia JM Trivedi (pictured) and director Gautham Radhakrishnam will join Integreon’s board as part of the deal.

Integreon says it will use the cash to grow its range of services, open new delivery centres and seek strategic acquisitions. The company bought strategic research agency Grail Research from its parent company Monitor Group last year.

Actis senior partner Paul Fletcher said: “Outsourced professional services are one of Actis’s core investment strategies and Integreon represents a best-in-class investment in this sector. Leading international corporations, financial institutions and law firms harness the specialist knowledge capabilities of the emerging markets, and Actis’s investment in Integreon further strengthens this link.”

Integreon CEO Liam Brown added: “Actis’s long-established understanding of emerging markets, along with their experience investing in business outsourcing makes them an ideal partner for Integreon.”
