The annual Futures Industry Conference at the Boca Raton Resort & Club is great for catching up with old friends and clients, but each year, new attendees arrive to make their name known. Jim Kharouf sat down with Lilia Severina, collocation and proximity hosting director of Interxion (pronounced Inter-Action), which is based in Amsterdam and went public in January. (The firm announced its first quarterly earnings report on March 23, 2011) Severina spoke about what the firm does in co-location and its goal to bring more U.S. clients over to Europe, where its operations are well established. Q: Let's start with who Interxion is. A: Interxion is a co-location and proximity hosting firm which specializes in capital markets and finance, along side other verticals. The area of capital markets has been very important for us because Europe today has the largest community of participants. Our main facility hosts over 200 capital markets participants in London.
