Mr Evans, 44, joined the language services provider in March 2016 as director responsible for the implementation and performance of the group’s £120m interpreting contract with the Ministry of Justice.
He was closely involved in final contract negotiations and oversaw the successful implementation of the complex contract, maintaining a strong client relationship throughout.
Mr Evans has since led the development of the fast-growing group’s revenue generation plan and worked in various roles in global sales functions.
He said: “At thebigword, we believe that language is the final barrier to peace and prosperity.
“Our expert linguists help deliver the smooth administration of justice, they bring reconciliation to war-torn countries and they ensure that multinational brands can sell to customers in their own languages.
“There is a multi-billion dollar growth opportunity in the language services market and we intend to capitalise on it with our great technology and great people.”
Larry Gould, founder and chief executive, said: “Paul has impressed us with his commercial leadership. I am delighted to welcome him to the board and am confident he will be a great success in his new role as global sales director.”
The Leeds-based group has 10 offices across the world, including New York, Dusseldorf, Beijing and Tokyo, a workforce of 600 people and a network of 14,000 expert linguists.
Revenues increased by more than 40 per cent to £60m in the year ending May 2017.
Mr Evans started his career as a avionics apprentice at the Ministry of Defence.
He went on to hold senior project management positions at blue chip companies including BAE Systems and Pearson Group.
Prior to thebigword, Mr Evans worked as a consultant on various business change and commercial development programmes in the private sector.
He grew up in North Wales and outside work enjoys spending time with his young family.
