Ocusell is proud to announce its latest partnership with OneKey MLS, the largest Multiple  Listing Service in New York.

homes on Long Island—they needed a listing management solution flexible enough to handle a wide range of property types and business rules. 


Enter Ocusell List™. Designed for speed, accuracy, and adaptability, it streamlines the entire listing process. Leveraging advanced AI tools and real-time validation checks, agents can reduce listing creation time by up to 82%, cut compliance violations by over 75%, and publish to multiple MLSs instantly—all from a single platform.


“At OneKey® MLS, we’re committed to empowering our 43,000 real estate professionals with  innovative tools that enhance efficiency, collaboration, and compliance,” said Richard Haggerty, CEO of OneKey MLS. “Ocusell’s platform gives our agents and brokers their time back by streamlining the listing process and reducing compliance issues before a listing ever goes live. This partnership reflects our ongoing mission to deliver real value at every stage of the listing lifecycle—for both our members and our MLS staff.”


Ocusell’s platform works with a broad spectrum of property types, ensuring that listings are  created quickly, accurately, and in compliance with OneKey MLS rules. Real-time validation checks automatically alert agents to potential issues before a listing goes live, improving both the speed and accuracy of the listing process.


“OneKey MLS is an exemplary forward-thinking MLS that recognizes the value of streamlining  the listing process while maintaining compliance,” said Hayden Rieveschl, CEO and Co-founder of Ocusell. “This partnership marks an exciting next step in the evolution of MLS technology and data management.”


OneKey MLS joins previously announced partnerships with FMLS in Georgia and HIVE MLS  in North Carolina, South Carolina, and Georgia, bringing Ocusell’s user base to over 100,000 professionals in just a few months.
