What Software Partners does

Software Partners LLC is a privately held healthcare interoperability software company founded in 1992 and headquartered in Encinitas, California. Since securing its first contract with San Diego County in 1997, the company has focused narrowly on immunization information systems, building a portfolio of products under the MatchMerge brand — including the Matchmerge Immunization Registry (MIR), Matchmerge Decision Support v11 (MDS v11), Matchmerge Immunization Destination (IZD), MatchMerge Patient Identification (MPI), and MatchMerge Data Exchange (MDE). These products are differentiated by a patented Master Person Index (MPI) architecture that links rather than merges patient records across providers, by a separately patented computational approach to CDC Clinical Decision Support for Immunizations (CDSi), and by a Service-Oriented Architecture (SOA) approach to healthcare interoperability that the company cites as reducing integration costs by approximately five orders of magnitude compared to point-to-point connections.

The company sells exclusively to U.S. state and county public health agencies and operates with a small team of 1-10 employees. Revenue is generated through one-time software licenses for initial installation combined with recurring maintenance and support agreements, with expansion revenue available as customers add participating organizations, data types, or compliance requirements. Distribution is direct via phone and email, and pricing is not publicly disclosed. The MatchMerge Services suite holds ONC-Certified EHR 2014 Edition status (Modular, Ambulatory; InfoGard Certification #IG-2526-14-0011), and the company has contributed to IHE, HL7, OMG, and HIMSS standards and publications. Named customers include San Diego County (since 1997), North Dakota, Wisconsin (WIR), and California (CAIR2). The company has no disclosed outside investors, parent company, or funding rounds.

Data limitations are material: Software Partners discloses no revenue figures, no headcount trajectory, no recent funding activity, and limited post-2022 updates on its public-facing site, which constrains confident assessment of scale, momentum, and growth direction.

Revenue model

1. Software Licenses and Services: Initial installation of MatchMerge products with standard maintenance and support agreements. Customers may expand the system to accommodate additional participating organizations, data volumes, new data types, new uses, custom interfaces, hardware platforms, new security/hosting requirements, new data exchange standards, and new government regulations—many of which incur additional costs.
2. Maintenance and Support: Ongoing maintenance and support agreements following initial purchase, with expansion opportunities for additional capacity, features, and compliance requirements.

Core offering

Software Partners develops and licenses the MatchMerge suite of healthcare interoperability software for immunization information systems. Its core offerings include a Master Person Index-based immunization registry, CDC CDSi-compliant decision support, a public health gateway, and standards-based data exchange and patient identification modules. Customers are state and county public health agencies and healthcare providers that license the software with installation plus ongoing maintenance and support.

Product overview

Software Partners offers a unified portfolio of healthcare interoperability products centered on immunization information systems. The core offerings include Matchmerge Immunization Registry (MIR) as the foundational registry using patented MPI-based record linking, Matchmerge Decision Support v11 (MDS v11) as the immunization forecaster built on CDC CDSi standards with a patented computational approach, and Matchmerge Immunization Destination (IZD) as a public health gateway extracting core functions from traditional registry architecture. These are complemented by MatchMerge Services modules including MatchMerge Patient Identification (MPI) for master person indexing and MatchMerge Data Exchange (MDE) for standards-based HL7/CDA data exchange. The entire MatchMerge Services suite achieved ONC-Certified EHR status under the 2014 Edition. The company's approach is distinguished by its patented replication-based MPI architecture that links rather than merges records, preserving provider source control—a principle now standard in Enterprise Health Record systems.

Functional benefit

Products and services

• Matchmerge Immunization Registry (MIR) Immunization registry software using a patented Master Person Index (MPI) architecture that links records from different providers for a common patient rather than merging them, preserving source control and maintaining data accuracy for secondary-use public health records. Used by state and county public health agencies.
• Matchmerge Decision Support v11 (MDS v11) Immunization decision support service that complies with CDC's Clinical Decision Support for Immunizations (CDSi), using a patented computational approach that automatically handles all combinations of vaccine series, products, demographics, and medical history to produce accurate forecasting recommendations. Used by public health immunization registries.
• Matchmerge Immunization Destination (IZD) Public health gateway server that extracts core immunization registry functions—data exchange, record matching, and decision support—separating them from data entry functions, designed to be retrofitted onto existing immunization registry infrastructure to unify regional systems. Supports opt-in/opt-out patient privacy.
• MatchMerge Patient Identification (MPI) Master Person Index service providing Register and Query operations for cross-referencing patient identifiers across healthcare systems, implementing sophisticated probabilistic matching algorithms and IHE, HL7, and OMG standards. Used by health information exchanges and integrated delivery networks.
• MatchMerge Data Exchange (MDE) Standards-based data exchange service supporting HL7 Versions 2 and 3, Continuity of Care Document (CCD) formats, and Cross-Enterprise Document Sharing (XDS), enabling any-to-any data exchange through a bus model with multiple transport options (Sockets/MLLP, HTTPs/REST, SFTP, SOAP, batch file).

Quantifiable outcome

• SOA approach reduces healthcare interoperability costs by approximately 5 orders of magnitude compared to point-to-point connections (from 184 trillion CDN to 2.2 billion CDN estimated by Canada Health Infoway)

Broad incumbents

• Lyniate (Rhapsody): Lyniate's Rhapsody and Corepoint integration engines handle HL7 v2, X12, and FHIR routing and transformation, competing with Software Partners' MatchMerge Data Exchange for healthcare interoperability middleware deals.
• NextGen Healthcare (Mirth): NextGen's Mirth Connect (open-source HL7 integration engine) competes with MDE on interoperability plumbing, and NextGen's ambulatory EHR includes immunization reporting that overlaps with Software Partners' public-health footprint.
• Oracle Health (formerly Cerner): Oracle Health's Millennium EHR includes immunization forecasting and bidirectional registry interfaces, representing a large-incumbent competitive threat to Software Partners' provider-side integration business.
• InterSystems: InterSystems offers HealthShare, an interoperability platform handling HL7 v2, FHIR, and MPI functionality that competes with Software Partners' MPI and MDE products at the healthcare-enterprise level.
• Orion Health: Orion Health provides HIE, MPI, and population-health platforms including immunization-related data exchange, competing with Software Partners on cross-system patient identification and HIE infrastructure.
• Epic Systems: Epic's Care Everywhere and Cosmos platforms include immunization exchange and reporting functions; while not a registry vendor, Epic's scale can disintermediate niche IIS middleware like IZD in provider-side workflows.
• Gainwell Technologies: Gainwell Technologies operates and modernizes several state immunization registries and broader Medicaid/public-health IT systems, making it a larger incumbent with overlapping IIS and HIE capabilities.

Direct peers

• Envision Technology Partners: Envision Technology Partners develops WebIZ and other state immunization information systems, directly competing with Software Partners for IIS contracts at state and county health departments.
• HLN Consulting: HLN Consulting builds open-source immunization registry and decision support software (including ICE and awardee-based solutions), competing with Software Partners' MIR and MDS v11 in the public-health IIS market.

Others

• Deloitte (Public Health practice): Deloitte operates and implements several state immunization information systems under multi-year contracts, often partnering with or competing against Software Partners as a systems integrator in the IIS procurement space.
