The mortgage industry has long accepted high origination costs as inevitable.
Better proved otherwise.
Its generative AI loan agent Betsy, powered by ElevenLabs Agents, handles nearly 100,000 mortgage-related phone calls per month, automating 35.5% of borrower inquiries end to end.
In 2025 alone, Betsy placed 1.89 million inbound and outbound calls, saving Better's loan officers more than 1,666 hours of human time each month.
The results have transformed mortgage economics: a 41% reduction in average cost to originate and a 100% increase in lead-to-lock conversion in 2025.
The Mortgage Economics Problem
Mortgage origination is famously expensive.
Every borrower inquiry requires eligibility checks, pricing conversations, and rate locks—all manual, all time-consuming, and all prone to errors.
Better founder and CEO Vishal Garg put it simply: "We built Better to be AI-native from day one.
By combining Tinman with ElevenLabs' technology, we've scaled the first voice-based AI loan agent built exclusively for the mortgage industry".
How Betsy Works
Betsy is layered on top of Better's proprietary loan engine, Tinman, which computes pricing, eligibility, and approvals.
ElevenLabs Agents serve as the controlled voice interface, communicating Tinman's outputs to borrowers.
All regulated steps—including credit pulls, authentication, rate locks, and transfers to human consultants—require explicit consent and adhere to state licensing requirements.
Orchestration runs entirely within Better's environment through an MCP-based multi-agent system, while calls terminate at a single ElevenLabs Agent endpoint.
The Human Impact
These gains have allowed Better's licensed consultants to shift away from repetitive follow-up tasks and focus on higher-value advisory work—helping borrowers navigate complex scenarios and make informed financial decisions.
By moving routine eligibility checks, pricing conversations, and rate locks to an AI voice agent, Better has improved both borrower experience and unit economics without compromising compliance.
Why This Matters for Financial Services
Better's success demonstrates that voice AI can thrive in the most regulated environments.
A key factor in selecting ElevenLabs was platform stability under high tool-call volume.
In production, a single borrower conversation may trigger dozens of internal system calls.
For financial services workflows that span multiple systems and regulatory checkpoints, reliability at scale is critical.
