From Pioneer to Category Leader

Five9 was founded by five technology visionaries who left a leading player in the call center industry to create their own company in December 2001. These visionaries understood the untapped potential of Voice-over-IP and the emerging Software-as-a-Service model.

Their vision was to deliver the value of leading contact center software at an affordable price, and they saw how a cloud-based solution could dramatically improve return on investment results. Their commitment to service excellence is embodied in the company name—the five nines of reliability—typically associated with world-class telecommunications providers.

Using their own investment, they released the first version of the Five9 Virtual Call Center in March of 2003. Since then, with a strong executive team and top-tier investors fueling continued success, Five9 has outpaced the hosted call center software industry.

With over 360 employees world-wide, Five9 has one of the largest engineering organizations in the industry, allowing the company to be at the forefront of innovation in the cloud-based contact center space. The company revenues have grown at 50%-70% for each of the past four years. Since the company's inception, Five9 has steadily acquired customers of increasing size and scope of business needs, and now serves all customer size bands in the on-demand contact center software market: Small and Medium-Sized Businesses, Mid-Market, and Enterprise.
