Companies that use Five9

Source: Analysis of Linkedin bios of 350 companies that use Five9

I noticed that Five9's typical customers are companies dealing with high-volume human interactions at scale. These aren't tech startups building apps. They're healthcare providers managing patient inquiries, financial institutions handling account questions, utilities serving residential customers, insurance companies processing claims, retailers managing orders and returns, and transportation companies coordinating logistics. What unites them is the operational reality of fielding thousands of daily customer contacts across multiple channels.

These are predominantly mature, established enterprises. The signals are clear: employee counts typically range from 200 to 5,000+, many reference founding dates in the 1900s (some going back to 1853, 1907, 1917), and they operate across multiple states or countries with extensive physical footprints. When funding is mentioned, it's usually debt financing or private equity rather than venture capital, suggesting profitable operations seeking growth capital rather than runway extension.
