Outbound calling can move fast and, in the mortgage industry, involves important compliance responsibilities, which can add challenges of accuracy at scale. Rocket Mortgage approached Marr Labs with a clear goal; elevate outbound performance in a way that creates a smoother path for customers and supports bankers.
Together, we set out to build an intelligent, efficient outbound tool that works reliably in the real world and adapts with every conversation.
Outbound engagement shapes each customer’s experience through countless small moments, from choosing the right time to reach out, to offering the right message, understanding their needs, easing concerns, and guiding them smoothly to the help they need. Marr Labs’ AI voice agents were built to manage these complexities with consistency, accuracy, and a natural phone experience.
Today, customers move through the process with less friction as agents confirm interest, understand needs, gather essential details and connect them with the right support. The effects carry through operations and banker workflows and ultimately shape a smoother experience for Rocket Mortgage’s clients.
The relationship is driven by tight feedback loops, structured experimentation, and rapid development cycles. Marr Labs and Rocket Mortgage use a disciplined testing framework to evaluate every change — from conversational phrasing to routing logic — ensuring each improvement is validated before it scales.
This ongoing collaboration has produced:
Outbound is less ambiguous and is now becoming a repeatable, measurable, ROI-driving tool.
Marr Labs provides the adaptive agent tool. Rocket Mortgage brings operational depth and a culture of speed and putting the client first. Together, the teams have built a tool that is:
This is more than automation. It is a new model for how AI and humans collaborate to drive value.
Inbound support has evolved rapidly through AI. Outbound is the next major frontier, and Rocket Mortgage is already moving forward. The combination of Rocket Mortgage’s innovation mindset and Marr Labs’ agentic tool is creating a future where:
The future of lending won’t just be faster.
It will be more personal, more intelligent, and more efficient.
And that future is calling.
