Insightstream offers to the market more than 90 years’ combined experience from veterans of the data-driven marketing industry. The company was formed in 2013 by Gary Selby, a joint founder of Information Arts, and the merger of Robert Clark’s EMEA Data Group and Geoff Downer Associates.

Gary Selby, CEO


A B2B global data marketing specialist, Gary has been working with data for over 25 years. He passionately believes that getting data ‘right’ is a step forward for a business, because it allows the insight from data to drive many key areas, including customer acquisition and retention, channel management, product development and logistics planning. In 2000, Gary co-founded Information Arts, which was purchased by Harte Hanks in 2010.

Robert Clark, Sales Director


Robert leads Insightstream’s global sales group and is responsible for strengthening and cultivating the company’s relationships and business with customers, channel partners and enterprise end-users.

Robert was previously the founder and Managing Director of the EMEA Data Group. This full-service company provided both tactical and strategic marketable data that covered all aspects of demand creation and creative data solutions across Europe, the Middle East and Africa.

Before running the EMEA Data Group, Robert spent 12 years with US marketing giant Harte Hanks Inc.
