OPEN SOFTWARE TECHNOLOGIES INC

Open Software Technologies Inc. specializes in custom computer programming and maintenance of legacy mainframe software systems, with deep expertise in REXXTools/MVS environments. The company delivers ongoing support, enhancements, and service components for mission-critical applications running on IBM z/OS platforms, ensuring continuity and performance for government systems that rely on established mainframe architectures. Their technical focus includes scripting automation, system integration, and long-term software sustainment, particularly for high-availability environments where stability and backward compatibility are paramount. A key differentiator is their proven ability to maintain and modernize decades-old REXX-based toolsets without disrupting core operations, making them a trusted partner for agencies dependent on legacy infrastructure. The contractor has established sustained relationships with the Department of Veterans Affairs, providing ongoing maintenance and service components for REXXTools/MVS, and has also supported the Social Security Administration with similar legacy system sustainment. Additional work for the Department of Agriculture demonstrates their capacity to adapt core capabilities across federal domains requiring robust, reliable mainframe software support. These engagements reflect a pattern of repeat, mission-critical contract renewals, indicating strong client retention and operational reliability. Their primary industry focus lies in custom computer programming and related services under NAICS 541511 and 541519, with supplemental activity in software publishing under 513210. This positions them as a niche provider of specialized mainframe software sustainment rather than general-purpose IT services, serving federal agencies with complex, long-lived systems that demand deep technical familiarity and low-risk modernization approaches. Open Software Technologies Inc. is a small business structured as a 2L entity, headquartered in Altamonte Springs, Florida. While currently holding no formal government certifications, their consistent performance on sensitive federal contracts underscores their credibility in delivering secure, compliant legacy system support within the federal IT ecosystem.
