Overview
Five9 is an American company founded in 2001 that sells cloud contact centre software, and it was one of the first vendors to argue that call centre infrastructure belonged in a data centre it operated rather than in each customer's building. Its platform handles inbound and outbound voice, digital channels, workforce management and increasingly artificial intelligence agents that resolve interactions without a person, sold mainly to mid-market and enterprise service organisations. Headquartered in San Ramon, California and listed on Nasdaq, it competes with NICE, Genesys and the contact centre products bundled into larger communication suites.

Products
Outbound and Dialer
Predictive and compliance-managed outbound calling for collections and sales teams. American telemarketing regulation is strict enough that compliance features rather than dialling speed decide the purchase.
five9.com
Workforce Engagement Management
Forecasting, scheduling and quality management for contact centre staff. Scheduling accuracy is what determines whether a centre meets its service levels, so this module is usually bought alongside the core platform.
five9.com
Agent Assist
Real-time transcription, guidance and after-call summarisation for human agents. It is the least disruptive artificial intelligence product to sell, because it makes existing staff faster rather than replacing them.
five9.com
AI Agents
Voice and digital agents that resolve customer interactions autonomously. Pricing is moving toward outcomes rather than seats, which is a genuine threat to a business that has always been paid per agent licence.
five9.com
Intelligent CX Platform
The cloud contact centre covering routing, voice, digital channels and reporting. Selling it as a single platform rather than as components is what lets a mid-market buyer replace an on-premises system without running an integration project.
