Five9 is a cloud contact centre software provider based in the United States and one of the established vendors in the contact centre as a service market.

Call recording, quality management, workforce management and speech analytics support performance and compliance, while Five9’s AI offerings include intelligent virtual agents, agent assist with real-time guidance, and automated summaries. Supervisors can monitor queues and agents through real-time dashboards, and reporting provides historical insight into service levels and campaign results.
