Ray founded Hostelworld.com in 1999 when he identified an opportunity to introduce online bookings to youth and tourist hostels. As CEO, Ray grew the company to become the leading worldwide brand with distribution contracts in 170 countries and sold it in November 2009 for more than $500MM.

It's a dollar symbol, but the title says "1/2 billion euros"...

(highest price I've seen listed for the sale)
