Summary

A company deploying real production voice agents for banks and credit unions has identified key lessons from their experience. Only 18% of their target industry currently makes outbound calls with human beings, presenting a significant opportunity for automation. The voice agents handle various use cases, including welcome calls for new customers, reactivation calls for inactive accounts, and collections calls. A critical factor for success has been defining clear metrics with clients during onboarding, enabling measurement, post-call actions, and auditing to ensure calls achieve their intended outcomes. This approach has led clients to expand from one or two initial use cases to seven or eight different call types, resulting in thousands of calls monthly and demonstrating clear ROI.

Key takeaway

For executives in financial institutions considering AI adoption, focusing on voice agents for outbound calls represents a significant opportunity to automate functions currently not being performed. By clearly defining success metrics with your vendor and starting with high-impact use cases like welcome or reactivation calls, you can quickly demonstrate ROI and build confidence, paving the way for broader adoption and substantial operational efficiency gains.
