Regal ties its voice AI agents into Five9’s contact center platform

Regal Voice is pushing its autonomous voice agents into Five9’s world. The two companies have paired up so Five9 customers can use Regal through Five9’s AI Agent Connect program, which is basically a storefront for outside AI vendors.

The hookup runs both ways. A Five9 call event can trigger a Regal follow-up by text or by an outbound call from one of Regal’s AI agents, and no one has to queue that by hand. When calls finish, Five9 sends Regal the record: what campaign it came from, how long it ran, how it ended, and which agent handled it. That means the next touch, whether it comes from a person or an AI system, starts with the same context.

There’s also a routing angle baked in. Regal’s journey orchestration software scores contacts for intent, and the ones it flags as high intent can be dropped straight into a Five9 outbound campaign. Again, no manual swivel-chair work in the middle.

Regal co-founder and CEO Alex Levin says the pitch is aimed at enterprise contact centers, especially in regulated industries, where scripts and workflow discipline matter more than chatbot theatrics. The company, founded in New York in 2020, sells into healthcare, insurance and education. It says its agents handle inbound and outbound calls across sales, support and operations, with more than 200 enterprise customers and data from over 500 million calls feeding the system. Regal claims a 99.5% resolution rate without human handoff and says it has raised $83 million so far, including a $40 million round in October 2024.

For Five9, the deal fits a broader move toward agentic software. The company says it serves more than 3,500 enterprises in more than 140 countries, has been cloud-based since 2001, and uses its own Genius AI layer. Its latest quarter, reported on April 30, came with an 18% stock jump, faster subscription revenue growth for a second quarter, and a higher full-year outlook.
