OS33 is a software development company based in New York, originally operating from 33 East 33rd Street, focused on secure workspace solutions for financial services and other security- and compliance-driven industries. The firm served registered investment advisors, broker-dealers with independent representatives, and managed service providers, delivering a turnkey platform that enables productivity across distributed work environments while maintaining security and regulatory compliance. By 2019, OS33 began evolving into a new entity, Venn, to address a broader set of customers and the changing landscape of remote work, including the rise of software-as-a-service and increasingly complex regulatory requirements. OS33’s legacy and ongoing operations underpin the development of Venn, which targets secure BYO-PC scenarios and aims to isolate business activity on company-controlled enclaves installed on user devices, offering a more cost-effective alternative to traditional virtual desktops. The company serves a diverse clientele, with notable names in finance trusting its solutions to meet standards from FINRA, SEC, NAIC, and SOC 2, while continuing to support long-time customers through the transition to Venn.
