About Stone ARX
Real estate is overdue for modernization
Real estate is one of the largest industries in the world—yet the transaction process still runs on fragmented tools, manual handoffs, duplicated data entry, and opaque status updates. That creates delays, disputes, unexpected costs, and stress for everyone involved.
Stone ARX exists to modernize that reality.
We're building a transaction operating system that makes real estate deals clear, verifiable, and efficient—so buyers, sellers, brokers, agents, capital providers, and public agencies can move through a shared lifecycle with less friction and more certainty.
Why innovation matters now
Today's clients expect speed, transparency, and digital-first service in every industry. Real estate should be no different. The market is demanding:
Shorter timelines from intent to close
Lower costs by reducing redundant work and delays
Clear accountability so tasks aren't lost in email chains
Verified records to reduce disputes and improve compliance
Better collaboration across parties without losing control
Stone ARX is designed to deliver those outcomes through standardized workflows, role-based access, and real-time deal visibility.
Our origin
Founded in 2020, Stone ARX was formed around a simple conviction: real estate transactions should be transparent, efficient, and accessible—without sacrificing control or trust.
We saw an industry where deals often slow down not because people aren't working hard—but because the process is broken: disconnected systems, incomplete packages, unclear responsibilities, and late-stage surprises.
Stone ARX was built to fix the process itself—by organizing the transaction lifecycle and giving every party a shared, auditable source of truth from lead → client → listing → deal → close.
Our mission
Make real estate transactions fair, fast, and verifiable—at scale.
Our values
Transparency
No hidden handoffs. No mystery timelines. Stone ARX promotes clarity in deal status, requirements, and responsibilities—so clients and professionals can move confidently.
Innovation
We invest in workflow automation, structured data, and secure collaboration to reduce friction and modernize how transactions are executed.
Excellence
We aim for excellence in both technology and service—because real estate outcomes depend on execution, not just information.
Trust & Security
Real estate requires trust. Stone ARX is designed around verification, permissioned access, and auditability to protect all parties and reduce risk.
