SAN CARLOS, Calif. — December 17, 2025 — Leads & Copy — Retell AI has announced the first automated QA solution for Voice AI. Retell Assure automatically monitors Voice AI calls and makes improvements, eliminating the need for humans to spot check voice AI interactions.
The company’s co-founder and CEO, Bing Wu, said that automated quality assurance was the number one request of their enterprise customers, which is the fastest-growing customer segment. Wu said that these companies are deploying voice AI at high scale and need to be sure the technology remains solid over time, and Retell Assure lets them do that without requiring human agents to monitor calls. He added that this is a big step forward in their strategy to become the AI Voice agent platform of choice in the enterprise.
Typically, companies that deploy Voice AI agents ensure quality by having human agents check a sampling of recorded voice AI calls. An efficient team may be able to check 1-2 percent of all calls. Feedback is provided to an AI engineer who then reviews potential issues and updates Voice AI models where appropriate. The process can take weeks, during which model problems can impact many thousands of customers.
Retell AI’s new Retell Assure feature monitors 100 percent of Voice AI calls and automatically tweaks voice AI models immediately as needed to ensure models are performing as intended.
Retell Assure is available as part of the Retell AI Voice AI Platform starting January 1, 2026. Current Retell AI customers who want early access to the new feature can email support@retellai.com.
Retell AI’s conversational AI platform is quietly but rapidly transforming how businesses automate phone conversations with human-like precision. Since its launch, Retell AI has seen over 300% user growth quarter-over-quarter, and its technology is now powering 40M+ real-time AI phone calls every month across sectors like healthcare, logistics, real estate and e-commerce. The company has seen a 3x increase in monthly recurring revenue over the past six months, with an ARR of $35M+.
According to the company, a major U.S. insurer automated 75–80% of support calls with Retell AI; inbound support now runs 24/7 across multiple languages, with higher customer satisfaction and lower cost per policy; and abandon rates have been reduced from 20 to 5 percent.
Retell AI is the first enterprise-grade AI voice agent platform helping corporate call centers automate tier-one calls using AI voice agents that are indistinguishable from humans. Retell’s platform reduces labor costs, improves first-call resolution, and frees up human agents to focus on complex or sensitive issues. With rapid no-code deployment and high configurability, enterprises can launch Retell’s fully automated voice agents in days—not months. Retell serves thousands of businesses and now powers 40+ million minutes of phone conversations every month.
