Interxion

European Telecom Exchange BV was incorporated on 6 April 1998, and (after being renamed Interxion Holding B.V. on 12 June 1998) was converted into Interxion Holding N.V. on 11 January 2000. Interxion completed its IPO on the New York Stock Exchange (NYSE) on 28 January 2011. Interxion was founded by Bart van den Dries. The first round of venture capital was provided by Residex together with some informal investors.

In February 2015, it was announced that UK-based data center operator Telecity would merge with Interxion, purchasing it in a $2.2 billion deal, thus creating a joint data-center operator, with a combined value of $4.5 billion. According to the two CEOs, a deal promised to deliver around $600 million in synergy savings. In May 2015, US data company Equinix announced it would be acquiring TelecityGroup for £2.35 billion ($3.6 billion), which would terminate Telecity's deal with Interxion.
