Keywords Studios, the provider of technical services to the global video games industry, has made a number of key appointments within its leadership team to strengthen the business. 

Igor Efremov has been appointed as chief commercial officer; Mark Rizzo as global operations director; Andrew Brown has taken up the newly created role of chief marketing officer; and Jamie Campbell has been named service line director for the engineering services line. 

Efremov had various roles in Enterprise Systems Management at Electronic Arts, before founding and running Sperasoft, which was acquired by Keywords in December 2017. 

In his new position, he will assume responsibility of Keywords' seven service lines from COO Giacomo Duranti and the company's business development activities from CEO Andrew Day.

Mark Rizzo is the former COO of Sperasoft, prior to which he held senior tech management positions at Electronic Arts, Sony, NCSoft and Trion Worlds.

Brown has a background in marketing and general management initially within consumer products groups including Danone, Coca Cola and Johnson & Johnson and held roles of UK managing director and SVP Americas at Activision Blizzard.  

Meanwhile, Campbell joined Keywords through the acquisition of d3t Ltd in October 2017. Prior to founding d3t, he was technical director at games developer and publisher THQ and has an early background in embedded systems engineering and games programming.

"These changes and additions to our leadership team at Keywords add capability and capacity as we continue to develop our global video games services platform," said CEO Andrew Day.

"Welcoming companies into the Keywords family and integrating them including to the extent of complementing the leadership team with talented individuals from those companies, is something we pride ourselves on and it is pleasing to see this being reflected in these latest people moves."
