What Theorem Solutions does
Theorem Solutions is a privately held UK-based software company founded in 1989 and headquartered in Tamworth, operating with an 11–50 employee team. It provides enterprise software for automated CAD migration, CAD data exchange, and 3D PDF publishing, marketed under the SpinFire portfolio. The company's core technology stack is a CAD data conversion, viewing, collaboration, and extended reality (XR) visualization platform that translates complex multi-CAD data into lightweight, downstream-consumable formats.
The product suite is built around four integrated offerings: SpinFire Convert (CAD translation and lightweight publishing across formats including 3DEXPERIENCE, CATIA V5, Creo, NX, JT, 3D PDF, and HTML); SpinFire Insight (desktop and mobile viewing, measuring, markup, and collaboration without requiring native CAD systems); SpinFire XR (immersive visualization in augmented, mixed, and virtual reality); and SpinFire Manage (PLM-oriented data management). The platform supports deep, named integrations with Siemens Teamcenter, PTC Windchill, and Dassault Systèmes 3DEXPERIENCE via API connectivity and automated batch processing, and is certified to ISO 27001, SOC 2 Type 2, and JOSCAR standards.
Theorem Solutions sells primarily into engineering and manufacturing organizations through a direct enterprise sales motion supported by a global reseller network, supplemented by API/SDK distribution for embedded and programmatic integration. Pricing is quote-based rather than publicly disclosed. Marquee end customers include Volkswagen, Ferrari, Renault, Volvo, Hyundai, Ford, and Magna in automotive, and Airbus, Lockheed Martin, Bell, Rolls-Royce, Pratt & Whitney, and Gulfstream in aerospace and defense, indicating a customer base concentrated in large industrial OEMs.

Theorem Solutions competitors and assessment
Company assessmentBroad incumbents
- Autodesk: Autodesk provides AutoCAD, Inventor, Fusion 360, and increasingly viewer/collaboration capabilities, competing with Theorem in CAD data exchange and lightweight publishing for multi-vendor engineering environments.
- Siemens Digital Industries Software: Siemens offers NX CAD and Teamcenter PLM, which dominate multi-CAD enterprise environments. A core Theorem integration partner, but also a broad incumbent whose expanding native capabilities compete with standalone interoperability tools.
- PTC: PTC provides Creo CAD, Windchill PLM, and the Vuforia AR platform, all of which intersect with Theorem's CAD translation, PLM data management, and XR visualization offerings. A core integration partner and adjacent platform competitor.
- Dassault Systèmes: Dassault Systèmes offers CATIA, SOLIDWORKS, and the 3DEXPERIENCE platform, which natively cover CAD authoring, PLM, and increasingly visualization. A core integration partner but also a potential platform competitor that could absorb interoperability into native features.
- OpenText (Visual Enterprise / Right Hemisphere): OpenText's Visual Enterprise (formerly Right Hemisphere) provides 3D visualization, CAD data publishing, and collaboration tools for enterprise asset and engineering data, overlapping with Theorem's Convert and Insight capabilities as part of a broader information management portfolio.
- Hexagon (HxGN SDx / visualization products): Hexagon's manufacturing intelligence division provides CAD/CAE visualization, measurement, and digital reality solutions for engineering and production environments, overlapping with Theorem's XR/visualization and interoperability positioning.
Direct peers
- Actify Inc. Actify is a CAD visualization and collaboration vendor whose SpinFire product was the original lineage of the SpinFire portfolio now referenced in Theorem's data. Comparable in CAD viewing, markup, and translation for manufacturing enterprises.
- Tech Soft 3D: Tech Soft 3D provides HOOPS toolkits for CAD data exchange, 3D visualization, and developer SDKs, and is the apparent owner/operator of the SpinFire product suite referenced in the data. Direct overlap with Theorem's CAD translation, viewing, and XR visualization capabilities.
- Elysium (Elysium Co., Ltd.): Elysium is a long-standing specialist in CAD data translation and interoperability, with a product portfolio (e.g., CADdoctor) directly competitive with Theorem's CAD translation and migration offerings for multi-CAD environments.
Emerging players
- Okino Computer Graphics (PolyTrans): Okino's PolyTrans and NuGraf products are specialized CAD/3D data translation and conversion tools, competing more narrowly with Theorem's translation and format-conversion capabilities in the multi-CAD interoperability niche.
