What VMS Software does

VMS Software, Inc. is a privately-held Massachusetts corporation founded in 2014 to assume stewardship of the OpenVMS operating system after Hewlett Packard Enterprise exited the market. The company develops, distributes, and supports OpenVMS — a mission-critical enterprise OS with 99.999% uptime capability and documented server uptimes spanning decades — now ported to x86-64 hardware and cloud platforms including AWS. Its product portfolio spans the core OS (OpenVMS V9.2-3), cluster-aware monitoring (VMSSPI), development environments (VMS IDE, VMS/XDE), web interfaces (WebUI), transaction processing middleware (ACMS), and an expanding set of integration and migration tools (WSIT, ACMSDI Gateway, PAMS API replacement, PostgreSQL client, FreeTDS, Skunk/Punk SQL bridges).

The company monetizes through a mix of software licensing, tiered support and maintenance subscriptions, and a full suite of professional services covering Alpha/Integrity-to-x86 migration, cloud migration, Rdb-to-PostgreSQL modernization, ongoing managed services, and training (including biannual courses and Bootcamp events in Boston and Malmö). Go-to-market is enterprise field sales targeting OpenVMS customers with mission-critical applications in nuclear power, manufacturing, financial services, and healthcare, supplemented by event-driven acquisition through Bootcamps, webinars, a community forum, wiki documentation, and an ISV Partner and Ambassador channel program. A free Community License Program serves over 1,000 members, providing a developer and talent pipeline.

The firm operates as a 100% remote organization since 2020, with employees distributed across U.S. states and a core population in a no-income-tax jurisdiction adjacent to its original Burlington, Massachusetts headquarters. Leadership comprises CEO Kevin Shaw, Director of Strategy Chris Brown (an 11-year DEC/Compaq/HP OpenVMS group veteran), Director of Application Services Brett Cameron, and VP of People Strategy Nicole Hart. The company holds exclusive rights to develop and distribute OpenVMS on x86-64, which underpins its competitive position as the sole commercial vendor serving the legacy OpenVMS installed base.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Stromasys: Provides VAX/Alpha hardware emulation on x86 and Linux, enabling OpenVMS to run on emulated hardware. This is the closest comparable business model: enabling OpenVMS workload continuity through a different technical approach (emulation vs. native x86 port).
• Sine Nomine Associates: Provides OpenVMS consulting, support, and ports. Directly comparable as a niche services and engineering firm supporting the OpenVMS ecosystem with similar customer profiles and skill sets.

Broad incumbents

• Hewlett Packard Enterprise (HPE): The former owner and developer of OpenVMS before exiting the market in 2014. As the broad incumbent that created and abandoned the platform, HPE is the historical anchor of comparability even though it no longer competes directly.
• OpenText (Micro Focus): Through the Micro Focus acquisition, OpenText supports and modernizes legacy enterprise software (COBOL, mainframe, etc.) — a directly comparable "own and maintain legacy mission-critical software" franchise at much larger scale.
• IBM: Owns and continues to develop proprietary enterprise operating systems (z/OS, AIX) and provides modernization services for mission-critical workloads. The broad incumbent counterpart in the mainframe/minicomputer space, with similar customer lock-in dynamics.
• Oracle: Holds adjacent legacy assets (Solaris, Rdb, MessageQ) referenced in VMS Software's own product roadmap as "products being replaced." Comparable as a broad incumbent with overlapping legacy enterprise software customers and competing migration destinations.
• Fujitsu: Long-standing provider of enterprise minicomputer and mainframe hardware/software (BS2000, etc.) with comparable mission-critical customer base and legacy continuation strategy. Comparable as a broad incumbent in adjacent legacy enterprise OS markets.

Emerging players

• Heirloom Computing: Specializes in COBOL and mainframe application modernization to Java and cloud. Comparable as an emerging player in legacy mission-critical application modernization with similar value proposition of preserving application investment.
• TmaxSoft: Provides mainframe rehosting and legacy operating-system alternatives (OpenFrame). Comparable as an emerging player offering an alternative platform for mission-critical legacy workloads rather than porting to standard infrastructure.
• Skytap (IBM): Cloud infrastructure purpose-built for hosting legacy workloads including OpenVMS. Comparable as a complementary/alternative path for customers deciding between native x86 port (VMS Software) and cloud-hosted legacy emulation.
