Dialogus
Dialogus is a San Francisco startup (Y Combinator S26) building infrastructure for enterprise voice agents. Instead of automating a single call, it aims to rebuild the contact center itself: AI voice agents that answer live phone calls, resolve customer requests end-to-end, execute workflows against CRMs and internal systems, hand off to humans when needed, and produce a full audit trail. The platform is SOC 2 compliant and, per the company, already handles thousands of production calls for large enterprises including Papa Johns, KFC and Totalplay.
