What multiSIM does
multiSIM BV is a Netherlands-based high-tech engineering company founded in 2017 that develops next-generation simulators for collaborative crew training, primarily serving defense and aerospace medicine customers globally. Its core technology consists of two proprietary software platforms: D-SIM, a distributed simulation framework positioned as 'the Linux for simulation' that enables networked simulators to operate under shared virtual conditions with high-performance SDK access to every simulation variable; and D-WORLD, a Unity-based high-fidelity real-time visual engine with physics models for aerodynamics, ballistics, and ground interaction. The product portfolio spans fixed-wing (F-35, F-16, PC-7, PC-9, T-6, A-29 Tucano), helicopter (Apache AH-64, Chinook CH-47, Cougar AS532, EC-135, Bell 206), and aerial-refueling (MRTT ARO Station) training systems, plus research facilities including a Simulation Innovation Lab with the DESDEMONA motion simulator and an Aeromedical Research Lab.
The company monetizes through simulation software licensing and development, custom engineering services leveraging D-SIM's rapid-development capability, and integrated training solutions ranging from desktop setups to full-motion simulators. Its go-to-market is enterprise field sales driven by defense trade shows (ITEC, I/ITSEC, IT2EC, Global Defence Helicopter), direct engagement with air forces and defense ministries, and a small set of strategic partnerships with integrators such as Leonardo, JFJ Aviation & Defence, Aechelon Technology, and 3D Perception. Reported customer relationships include the Royal Netherlands Air Force's Center for Man in Aviation and the Multinational MRTT Fleet. The 1-10 employee firm operates from Soesterberg, Netherlands, and is part of the Aeolus innovation consortium with research ties to TU Delft and TNO.

multiSIM competitors and assessment
Company assessmentBroad incumbents
- CAE: CAE is the world's largest pure-play civil and military aviation training company, providing full-mission simulators and training services for fighter, helicopter, and tanker platforms. It directly competes with multiSIM across multiSIM's core offerings (F-16, helicopter, MRTT refueling) but at much larger scale and with integrated hardware.
- Thales Group: Thales provides military simulation, training, and avionics systems across Europe, with strong positions in French and allied air force training contracts. Competes with multiSIM in distributed mission training and aerospace medicine training for European ministries of defense.
- Cubic Defense (Cubic Corporation): Cubic delivers air combat training, Live-Virtual-Constructive (LVC) systems, and immersive simulation including the acquired MetaVR and Simulated Strategic & Tactical Airborne Replay System (SSTARS) products. It competes with multiSIM in distributed training and LVC integration for air forces.
- Saab: Saab provides Gripen-related training simulations and a broader defense training portfolio, including naval and ground simulation. Comparable European-based prime competing for the same Nordic and broader European air force training budgets.
- Leonardo S.p.A. Leonardo is a global defense prime and multiSIM's flagship partner for the MRTT aerial refueling simulator. While current relationship is partnership, Leonardo's simulation division (Leonardo DRS and Leonardo Aircraft) competes in integrated training solutions for the same European air force customers.
- L3Harris Technologies: L3Harris is a top-tier defense prime with a substantial simulation and training business (including Link Training & Simulation, acquired from L3 Technologies), delivering full-mission simulators for fighter, helicopter, and transport platforms worldwide. Competes with multiSIM across the same aircraft portfolio.
Direct peers
- Elbit Systems: Elbit Systems is a major Israeli defense electronics and training systems provider, including fighter and helicopter simulators as well as immersive dismounted soldier training. Comparable to multiSIM in technology breadth and in serving Western/non-US defense customers.
- Bohemia Interactive Simulations (BISim): BISim develops VBS (Virtual Battlespace) and a suite of simulation software used widely by NATO militaries for serious games and tactical training. It is a direct competitor in the software-based distributed simulation and battle lab market, with comparable DIS/HLA standards support and Unity-based product heritage.
Emerging players
- SimIS, Inc. SimIS is a small-to-mid-scale US defense simulation and engineering services company specializing in M&S, training, and prototyping for the DoD. Comparable to multiSIM in size, posture (engineering services + simulation products), and reliance on defense/government customers.
Regional players
- ST Engineering (AgilSpace / Training Systems): ST Engineering's training systems division provides full-mission simulators and live-virtual-constructive training solutions primarily to Asia-Pacific militaries. It is a regional peer in the same aircraft simulation category but does not directly compete in multiSIM's primary European theater.
