Proxama CEO John Kennedy resigned from the business late last month and was replaced by Mark Slade who joined the Board earlier this year and headed up the Location Sciences division.
Kelvin Harrison, Chairman of the mobile location and data intelligence business, said: "John has led Proxama through a period of significant change. The company has been de-leveraged, refinanced and has transformed its strategy.
"It is now able to build on its network of assets and partnerships to focus on the mobile location intelligence market with a new executive team."
Slade founded and sold his mobile advertising business Fourth Screen to Opera Mediaworks, where he became MD for the EMEA region and helped grow the business to over $100m in revenues.
"I am taking the lead as the company launches into the location intelligence market with a range of products that have demand from marketing agencies and brands, as well as other sectors," stated Slade.
