What Stilo does

Stilo is a Canadian-headquartered software company specializing in XML and DITA content conversion and processing tools, serving enterprise organizations across technology, healthcare, aerospace, government, defense, and publishing sectors. The company operates as the primary operating entity of Stilo International plc, a publicly listed company on the London Stock Exchange (LSE:STL), with offices in Ottawa, Canada and the United Kingdom. Its customer base spans 40+ named enterprise organizations including Cisco, Intel, IBM, Oracle, SAP, Qualcomm, Airbus, the European Parliament, and Stryker, among others, with over one million pages of legacy content converted to DITA XML across these engagements.

The company's core technology is built around OmniMark, a proprietary specialist programming language for high-performance XML/SGML content processing that has been continuously developed since the company's early history (version 13 released May 2026). Stilo's product portfolio includes four core tools: OmniMark (the underlying programming language and development environment), Migrate (a cloud-based, pay-as-you-use conversion service supporting input formats including MS Word, FrameMaker, InDesign, RoboHelp, Author-it, DocBook, HTML, and SGML/XML, with output to DITA 1.1/1.2/1.3/2.0), Analyzer (a free content reuse analysis and reporting tool), and OptimizeR (a DITA content optimization service for topic deduplication and map/conref updates). The company also offers AuthorBridge, a guided DITA authoring solution for subject matter experts.

Stilo generates revenue through three primary streams: software licensing for OmniMark (subscription/recurring), usage-based cloud conversion through Migrate (pay-as-you-go), and professional services for complex enterprise conversion projects. The go-to-market combines enterprise field sales for large organizations with a self-service cloud platform for smaller teams, supported by free evaluations (60-day OmniMark trial, free sample conversions), a partner/reseller network, active presence at industry conferences (LavaCon, ConVEx, DITA Europe), and an educational content marketing strategy including a 137-page DITA XML FAQ knowledge base and a webinar series.

Broad incumbents

• Adobe Experience Manager: Adobe Experience Manager includes XML/DITA content management capabilities as part of its broader enterprise CMS offering. It competes for enterprise content operations budgets against Stilo's specialized DITA tooling stack.
• RWS Group (formerly SDL): RWS, which acquired SDL, is a global leader in language services, structured content, and DITA-based content management. Stilo's customers include SDL, and RWS competes broadly across the same enterprise content operations market with greater scale.
• Innodata: Innodata provides large-scale content services, data engineering, and digital content transformation for enterprises. While broader in scope, Innodata overlaps with Stilo's professional services for legacy content conversion and migration.

Direct peers

• IXIASOFT: IXIASOFT provides a DITA-native Component Content Management System (CCMS) for enterprise technical documentation. As a co-marketing partner with Stilo at CCMS Link, IXIASOFT sits in the same DITA structured content ecosystem and addresses overlapping enterprise customers.
• Vasont Systems (Emtex): Vasont Systems provides content management and XML/DITA solutions for technical documentation teams. It competes directly with Stilo's tools for managing, converting, and publishing structured enterprise content.
• Syncro Soft (Oxygen XML Editor): Syncro Soft's Oxygen XML Editor is a widely-used XML/DITA authoring and editing tool for technical writers. Both companies serve the same DITA technical documentation market with complementary authoring and conversion/processing tooling.
• Typefi: Typefi provides automated publishing solutions for structured content including DITA and XML. Both companies serve enterprise technical documentation teams converting and publishing structured content at scale.
• Heretto: Heretto is a cloud-native CCMS purpose-built for DITA structured content management and delivery. It competes for the same enterprise technical documentation budgets as Stilo's OmniMark/Migrate/OptimizeR stack.
• Fonto: Fonto (acquired by SDL/RWS) offers a browser-based structured content editor for DITA and XML. It serves the same enterprise authoring and content management use cases as Stilo's OmniMark/Migrate pipeline.

Emerging players

• Contentful: Contentful is a leading headless CMS platform used for structured content delivery. It represents the broader trend of headless/structured content architectures that compete with DITA-centric tooling for enterprise content operations modernization.
