ABOUT THE COMPANY
Valon is the leading AI platform for mortgage servicing, building the AI-native operating system for regulated finance.
Before providing the system of record that powers the entire industry, we built and ran our own mortgage servicer on it. That gave us a real regulated environment to prove our technology could replace the mainframe systems servicers have used for decades. Carrington acquired that servicer and adopted ValonOS as its core platform, allowing us to focus entirely on scaling our SaaS platform.
ValonOS is now on track to power 1 in 6 U.S. mortgages across major mortgage servicers like Newrez, Carrington, and ServiceMac. Every process on the platform is structured and programmable, enabling our AI agents to perform core servicing work, like handling payments, escrow, and homeowner questions, directly within the system's controls.
We recently raised a $150 million Series D at a $2.3 billion valuation by new investor Ribbit Capital, with continued support from existing backer a16z, amongst others.
SECURITY AT VALON
Our customers entrust us with some of their most sensitive and personal financial information, and it is the ultimate mission of Valon’s Security team to ensure we have sound programs, processes, and automation in place to safeguard our customers’ data. The Security team protects the infrastructure and data for processing billions of dollars of mortgage loans.
In addition to protecting Valon’s internal systems, the Security team partners closely with Product and Engineering to design and deliver secure, scalable, and trustworthy capabilities for ValonOS. We work cross-functionally across all teams at Valon to enable security throughout the organization. We engage with external security auditors, pentesting firms, and partners to continuously evaluate Valon’s security posture.
Valon offices are located in New York City and San Francisco, but we fully support remote work!
