I worked very closely with Five9 for years. I can say that every company has their flaws but the key thing I took away from my time with them is that technology is in service of business goals, not the other way around. There were always discussions of what a "perfect" system might look like, and, every time, cooler heads prevailed. They simply did what was needed to meet their business goals and there's something admirable about that clarity. Is Five9's product the best in call centers? No, but it's about an order of magnitude cheaper than the top product and works most of the time.
