What MicroDoc does

MicroDoc Computersysteme GmbH is a Munich-based private German software engineering company founded in 1991 and operating as a subsidiary of Akkodis. It serves enterprise customers across four primary verticals — automotive/transportation, energy, finance/banking, and industrial automation — with a portfolio that blends TCK-certified embedded Java runtimes (MicroDoc GraalVM Embedded and MicroDoc Embedded Java), Rust-based industrial edge applications for PLCnext controllers (OPC UA Browser, Diagnostic Cloud Azure/AWS), and software engineering services (Rust, Java, Cloud, Managed Operations). Named flagship customers include Daimler Truck AG (a 15+ year strategic engineering partner with a framework agreement extending through 2028), EnBW (EnergyBASE smart-home energy platform since 2015), Sparkassen Financial Group (OSPlus Neo banking framework), and an unnamed large German financial services provider (CI/CD migration from Bamboo to Jenkins).

The company's core technology is built around GraalVM Native Image ahead-of-time compilation (10x faster startup, 50% lower memory vs. traditional JVM) and full JVM-compatible embedded runtimes, both TCK-certified and offered with 15+ year long-term support. It is an official Oracle GraalVM Licensing partner, a member of the JCP Executive Committee since 2011 (re-elected 2020 and 2024), and a PLCnext Technology Partner publishing apps on Phoenix Contact's PLCnext Store. Domain-specific platforms include EnergyBASE, OSPlus Neo, the modular telematics/fleet-management platform, and the newly launched Certificate Dashboard for industrial PKI management. MicroDoc operates from Munich, Berlin, and Stuttgart.

Commercially, MicroDoc combines per-device version-locked perpetual licensing for embedded runtimes, long-term subscription support agreements (10–15+ years), project-based and multi-year framework engineering services, and managed operations on dedicated German infrastructure. Go-to-market is hybrid: direct enterprise sales for services and framework agreements, OEM/embedded licensing for runtimes, PLCnext Store marketplace distribution for PLC apps, and Akkodis-channel leverage for broader European reach. With 11–50 employees, MicroDoc is a small, specialized firm whose revenue, funding history, and ownership details are not publicly disclosed.

Revenue model

1. Software Licensing (Embedded Runtimes): Per-device, version-locked licensing for MicroDoc Embedded Java and MicroDoc GraalVM Embedded runtimes. One-time payment per device, valid for the device's entire lifetime. Optional extended support plans available for long-term support (10-15+ years) including security updates. Revenue depends on CPU performance class, number of cores, device volume, and custom porting NRE costs.
2. Enterprise Support Agreements: Custom enterprise support agreements with dedicated support, custom SLAs, and response times for high-volume projects or special requirements. Long-term support agreements (10-15+ years) include security updates for licensed versions.
3. Engineering Services: Specialized software engineering services in Rust, Java, Cloud, and Managed Operations delivered via consulting, project delivery, or team extension engagement models. Revenue is project-based or through strategic multi-year framework agreements with enterprise clients.
4. Managed Operations: Long-term operational management of customer software systems on dedicated German infrastructure. Includes automated CI/CD, monitoring, incident response, backup and recovery, OTA update infrastructure, and certificate lifecycle management.

Scale indicators10 records

Recent moves6 records

Expansion highlights6 records

Regional players

• Sysgo: SYSGO provides PikeOS RTOS and embedded Linux for European industrial, automotive, and aerospace customers, particularly in Germany and the DACH region. It is comparable to MicroDoc in geographic focus and embedded-systems tooling, but specializes in separation-kernel RTOS rather than Java runtimes.

Broad incumbents

• Red Hat: Red Hat builds and distributes Red Hat Build of OpenJDK (RHEL JDK), an open-source Java runtime. As a much larger incumbent in the Java distribution space, it competes for OEM embedded Java slots where MicroDoc plays, but its focus is broad across enterprise Java, not specialized embedded.
• Wind River Systems: Wind River provides VxWorks RTOS, Wind River Linux, and embedded development tooling for industrial, automotive, and aerospace markets. It overlaps with MicroDoc's embedded software tooling scope but as a much larger incumbent with broader platform coverage.
• IBM Semeru Runtimes: IBM distributes Semeru Runtimes (formerly Adoptium / Eclipse Temurin support) as part of its broader hybrid cloud and Java tooling portfolio. It overlaps with MicroDoc's Java runtime distribution business but at much wider enterprise scale.

Emerging players

• Qt Group: Qt Group provides Qt for MCUs and cross-platform UI frameworks for embedded and industrial devices, partially overlapping with MicroDoc's GraalVM Embedded UI Framework positioning for resource-constrained IoT devices.

Others

• Phoenix Contact: Phoenix Contact owns the PLCnext ecosystem and the PLCnext Store where MicroDoc distributes its OPC UA and Diagnostic Cloud apps. Although a technology partner rather than direct competitor, Phoenix Contact is the platform MicroDoc builds on and the closest commercial counterpart in industrial automation software.
• Eclipse Adoptium (Temurin): The Eclipse Adoptium community produces Temurin, the de facto open-source reference JDK. MicroDoc competes indirectly with Temurin for OEM embedded customers but as a community project rather than a commercial vendor, illustrating both the open-source alternative and MicroDoc's value-add (TCK certification, cross-compilation, 15-year support).

Direct peers

• COPA-DATA: COPA-DATA (zenon) builds industrial automation software including OPC UA servers, HMI, and PLC connectivity tools that compete with MicroDoc's PLCnext-based diagnostics and cloud-streaming products for the same industrial automation buyer.
• Bellsoft: Bellsoft distributes Liberica JDK and Liberica Embedded JDK, targeting the same OEM embedded Java customer base as MicroDoc. Both are JCP EC members competing for the same automotive and industrial embedded Java workloads.
• Azul Systems: Azul offers Azul Platform Core (Zulu) and Zulu Embedded for OEM embedded Java use cases. Like MicroDoc, Azul focuses on TCK-certified Java runtimes for the automotive, IoT, and industrial edge segments.
