When I started Gluu in 2009, I had no idea how difficult it would be to start an open source software company. Using the open source development methodology seemed like a good idea, especially for infrastructure software based on protocols defined by open standards. By nature, entrepreneurs are optimistic—we underestimate the difficulty of starting a business. However, Gluu was my fourth business, so I thought I knew what I was in for. But I was in for a surprise!
