Founded 10 years ago, Polish-based Outbox specialises in customer, digital and technology services working with leading platforms such as Salesforce, Microsoft Dynamics, Oracle and SAP. More than 250 Outbox employees will join PwC when the deal is finalised in February.

The move follows earlier acquisitions by PwC, including the European consultancy Mokum, and Booz & Company (now Strategy&), in 2014. The firm says the addition of Outbox Group will increase its contingent of technology practitioners to almost 3,000 across EMEA.

Ashley Unwin, PwC’s UK and EMEA consulting leader, said: ‘This acquisition represents a major milestone for PwC's UK and central and eastern Europe alliance and its commitment to invest in emerging markets. It is also a significant addition to our customer and digital capabilities and sees the establishment of a centre of excellence for these skills within PwC in Europe.’

Nicholas Mobbs, Outbox managing director, who will join PwC as a partner said: ‘This deal will provide PwC with the ability to offer a unique combination of world class skills and services, by delivering true cloud-based business transformation projects to the market and benefitting existing clients.

‘The potential market for customer experience, CRM and digital is estimated at over €6bn (£4.6bn) and we see this growing even in challenging economic times.’

The deal was signed on 31 December and is expected to be formally completed next month. Terms have not been disclosed.
