PwC is to acquire technology consultant Poland-based Outbox Group, a cloud-based CRM and sales automation specialist.

The addition of 250 employees from Outbox, a partner of Salesforce, Microsoft Dynamics, Oracle and SAP, will raise PWC’s headcount of technology specialists to almost 3,000 across EMEA. The acquisition agreement, signed on 31 December 2015, is expected to formally complete by January 31 2016.

Formed in 2005, Outbox provides consultancy over CRM, customer experience and marketing automation to 150 customers including Sky, Vodafone and Inmarsat. The Warsaw-based consultancy has now completed 250 CRM projects and has international offices in the UK, Germany, France and the Czech Republic.

The potential market for customer experience, CRM and digital is estimated at €6 billion according to PwC’s UK and EMEA Consulting Leader, Ashley Unwin. “This acquisition represents an investment in emerging markets and establishes centre of excellence for customer and digital capabilities within PwC in Europe,” said Unwin.

UK-based Outbox managing director Nicholas Mobbs will join PwC as a partner. “We are excited to join a leading consulting brand and combine business advice with user experience, marketing automation and CRM skills and services,” said Mobbs.

In other PWC news, cloud computing is contributing to a confidence crisis among enterprise chief executives, according to PWC’s global chairman Dennis Nally. Speaking at the 2016 Davos World Economic Forum, Nally said the cloud-based integrated global economy means that the world’s hot spots can instantly transmit end to end instability across the world.

Quoting the results of PwC’s 19th Annual Global CEO Survey, Nally said there were two outstanding sentiments among the survey group of 1,409 CEOs in 83 countries. The global economy and geopolitical tensions, the top two concerns, are interlinked now that technology acts as a lightning rod between hot spots, according to Nally. “We all know how integrated the global economy really is and not looking good is how I’d put it,” Nally told CNBC.
