What Satodev does

Satodev (legally SATODEV SAS) is a French software SME headquartered in Mérignac, founded in 2009, that specializes in RAMS (Reliability, Availability, Maintainability, and Safety) software for safety-critical industries. The company serves engineers and safety analysts in nuclear energy, aerospace, defense, and process industries, with named customers including TotalEnergies, Dassault Aviation, Thales, and EDF, and a broader base of hundreds of users across 20 countries. The firm is president-led by Cyrille Folleau and operates with a team of approximately 10 people, positioning it as a focused, high-touch specialist in a domain where regulatory qualification and domain expertise outweigh scale.

The core product portfolio rests on three pillars. First, Satodev is the exclusive commercial distributor of GRIF, developed by TotalEnergies, which provides fault tree analysis, SIL loop calculations, Petri nets, and Markov modeling, and is TÜV SÜD-certified for IEC 61508/61511 use cases. Second, the company exclusively distributes CECILIA, developed by Dassault Aviation, focused on fault tree and Model-Based Safety Analysis (MBSA). Third, Satodev owns and develops the FIDES Lab electronic reliability platform, currently distributed as a free tool, with FIDESLab PRO scheduled for launch in September 2026 as a paid premium tier. The company also resells complementary tools (FIDES, OREDA, MCS Safety Analyzer) and develops AltaRica Data-Flow language libraries, custom software, training, and consulting services.

The business model combines software resale and licensing, recurring maintenance contracts (100+ maintenance customers), training programs, bespoke development, and consulting. Revenue mechanics therefore span one-off license sales, annual maintenance fees, and services revenue, with FIDESLab PRO poised to introduce a SaaS-style recurring revenue stream. Distribution is direct and partner-anchored, leveraging the long-standing relationships with TotalEnergies and Dassault Aviation. The company is ISO 27001- and GDPR-compliant, participates in the IMdR FIDES 2022 working group, and has remained bootstrapped and founder-led with no disclosed external funding.

Revenue model

1. Software Licenses (Proprietary and Reseller): Sale of software licenses including SATODEV's own products and redistribution of GRIF (owned by TotalEnergies) and CECILIA (owned by Dassault Aviation). Licenses include corporate, education, and academic tiers. Software protection via Sentinel dongle (USB or software).
2. Annual Software Maintenance: Annual maintenance contracts providing access to updates, bug fixes, and new features. Maintenance not paid in year n is due in year n+1 on an iterative basis.
3. Training Services: Training on GRIF, CECILIA, MBSA, and theoretical dependability topics. Available in inter-company (at Bordeaux/Toulouse locations), intra-company (on client premises), and distance learning formats. Cancellation up to 15 days before training.
4. Technical Support: Software support including telephone assistance, optimization of software usage, explanation of features, and work methodology guidance.
5. Software Development: Custom development of scientific calculation software, import/export plugins, and result post-processing for third-party clients (TotalEnergies, Dassault Aviation, OREDA).
6. Consulting: Analysis of client problems and presentation of adapted solutions for dependability studies.

Core offering

SATODEV designs, distributes, and supports RAMS (Reliability, Availability, Maintainability, Safety) software tools for industrial clients. Its portfolio includes proprietary software (FIDES, FIDES Lab, OREDA, MCS Safety Analyzer, AltaRica) and software distributed under license (GRIF from TotalEnergies, CECILIA from Dassault Aviation). The company also provides annual software maintenance, technical support, custom scientific calculation development, consulting, and official training on dependability methods.

Product overview

SATODEV offers a portfolio of RAMS (Reliability, Availability, Maintainability, Safety) software products, with two main categories: (1) Distributed software - CECILIA (owned by Dassault Aviation) for fault tree and MBSA editing/computation, and GRIF (licensed from TotalEnergies) as a comprehensive suite for fault trees, SIL loops, Petri nets, and Markov graphs with Boolean, Simulation, and Markovian packages; (2) Proprietary software - FIDES for electronic system failure rate calculation, FIDES Lab (free tool) and upcoming FIDESLab PRO for FIDES 2022 methodology, OREDA for petroleum/gas industry failure rates, and MCS Safety Analyzer for cutsets post-processing. The company also develops custom software, provides maintenance and support services for 100+ customers, and delivers official training on its software and RAMS methods. AltaRica Data-Flow language support is provided for Model-Based Safety Assessment. Licensing protection uses Sentinel dongle technology.

Direct peers

• Relyence: Relyence offers cloud-based reliability prediction, FMEA, and reliability block diagram software (Relyence Predict, Relyence FMEA). Targets similar reliability engineering buyers with modern cloud-native tooling as a contrast to Satodev's desktop stack.
• ReliaSoft (HBK): ReliaSoft, now part of HBK (Hottinger Brüel & Kjaer), offers Weibull++, BlockSim, and similar RAMS analysis software for reliability and maintainability engineering. Comparable in customer base (aerospace, defense, industrial) and core functionality.
• Isograph: Isograph develops FaultTree+, Reliability Workbench, and AvSim — directly competing fault tree, Markov, and reliability software tools. They are the most direct head-to-head competitor to Satodev's GRIF and CECILIA portfolio in the same mission-critical engineer user base.
• BQR Engineering: BQR Engineering provides reliability prediction, failure rate databases, and RAMS software (FIDES, MIL-HDBK-217, Telcordia) for electronic and system reliability. Direct competitor especially in the FIDES methodology space where Satodev competes with FIDES Lab/PRO.

Broad incumbents

• PTC: PTC's Windchill PLM, Relex (now spun off) and broader reliability offerings compete for similar safety-critical engineering budgets. A larger incumbent with broader product portfolio but overlapping reliability analysis use cases.
• Siemens Digital Industries Software: Siemens offers Teamcenter, Simcenter, and other PLM/simulation tools with reliability and safety analysis capabilities. As a broad PLM incumbent, it competes for the same safety-critical engineering budgets as Satodev's RAMS tools.
• Dassault Systèmes: Dassault Systèmes' 3DEXPERIENCE platform, including the Cameo Systems Modeler (formerly No Magic) for MBSE/MBSA, competes in adjacent systems engineering space. Notable because Dassault Aviation (which owns CECILIA IP) is a separate entity within the broader group.
• ANSYS: ANSYS simulation suite (including ANSYS Sherlock, Relex Studio acquired from PTC) addresses reliability prediction and physics-of-failure at scale for electronics and systems. Broader portfolio but overlaps significantly in reliability engineering workflows.
