Gilbert Hodl, co-founder Tapkey (Vienna)

A self-proclaimed serial entrepreneur, Gil boasts a stellar track record for creating companies that derive their competitive advantage from customer centricity.

He’s the co-founder and former CEO of Lixto , which proved how big data could be leveraged to better understand markets—and which was eventually purchased by McKinsey & Company.

He’s also the co-founder and former CEO of Update Software , which began as a two-person CRM (note how the “C” stands for “customer”) startup which grew into one of Europe’s market leaders and went public on the German New Market in Frankfurt.

When he’s not in the office, Gil likes to keep fit; and naturally, he’s turned that passion into a business, too, called FitnessGoesOffice .
