What MaxLLG does

MaxLLG is a University of Exeter spin-out founded in 2018 that develops high-performance 3D electromagnetic (EM) analysis software for designing, analyzing, and optimizing nonlinear magnetic components and metamaterial systems. The company's core differentiator is a coupled Maxwell's equations + Landau-Lifshitz-Gilbert (LLG) solver that the company claims is the only commercial EM simulator able to correctly model magnetic phenomena in the RF, microwave, and millimeter-wave frequency ranges, where standard numerical methods rely on heavy approximation. The platform is delivered cloud-ready via Microsoft Azure, supports CAD initialization and HPC parallelization, and exposes Python and Matlab interfaces for visualization, dispersion analysis, and S-parameter computation. In February 2026 MaxLLG added an ML-powered inverse design tool that uses machine learning trained on its own simulation data to infer material structures for target electromagnetic responses.

The company serves four primary customer segments: telecommunications (RF devices such as circulators, isolators, filters, and couplers for 5G MIMO, IoT, and SatCom), defense and aerospace (frequency-agile and lighter components, radar systems), academic researchers studying magnetic materials and metamaterials, and—more recently—automotive and industrial buyers designing soft magnetic composite components for electric motors and inductors. Distribution is a mix of self-serve cloud subscription (Standard $29/month for 3 users, Professional $79/month for 20 users), free trial, direct enterprise sales with on-site installation, and consultation services. The company is sales-led and event-driven, actively exhibiting at the Materials Research Exchange 2026 and the 1st Metamaterials Manufacturing Conference in March 2026, and is closely embedded in the EPSRC-funded UK Metamaterials Network (1,000+ members, £2.5M funding through 2028).

The business is a 1–10 person, privately held UK team headquartered at Exeter Science Park, with development work also conducted at the University of Exeter Innovation Centre. The leadership pairs a commercially experienced CEO (Robin Sutton, formerly VP at JDS Uniphase) with an academically credentialed CSO (Feodor Ogrin, Associate Professor at Exeter, 80+ publications, 600+ citations) and several other team members who hold University of Exeter research or technical roles. No external funding rounds, parent company, or institutional investors are disclosed in the available data, and revenue is not publicly reported.

Core offering

MaxLLG develops and sells high-performance 3D electromagnetic (EM) analysis software that couples Maxwell's equations with the Landau-Lifshitz-Gilbert (LLG) equation simultaneously for designing, analyzing, and optimizing nonlinear magnetic components and metamaterial systems in RF, microwave, and millimeter-wave applications. The cloud-ready solver supports high-performance computing, time domain modelling, and parallelisation, and is complemented by an ML-powered inverse design tool, Python/Matlab interfaces, and consultation and on-site installation services.

Product overview

MaxLLG offers a unified high-frequency magnetics software platform centered on its core MaxLLG solver, which is a high-performance 3D electromagnetic analysis software that couples Maxwell's equations with the Landau-Lifshitz-Gilbert (LLG) equation for designing nonlinear magnetic components and metamaterial systems. The platform includes the LLG Module for magnetic device analysis, cloud computing capabilities via Microsoft Azure, Python/Matlab supporting tools for data analysis, visualization, animation, dispersion analysis, and S-parameters computation. A new ML-powered inverse design tool uses machine learning trained on simulation data to accelerate magnetic metamaterial design. Services include consultation, on-site installation, and HPC integration.

Broad incumbents

• Altair (Altair Feko): Altair Feko is a comprehensive 3D EM simulation solver for antenna design, placement, and radio-coverage analysis. It serves overlapping engineering customer segments as MaxLLG but is positioned as a broad EM tool rather than a magnetic-metamaterials specialist.
• ANSYS: ANSYS is the dominant commercial CAE vendor and offers Ansys Maxwell for low-frequency electromagnetic simulation. It competes with MaxLLG for EM design work but does not natively couple Maxwell's equations with the LLG equation for RF/microwave magnetic phenomena, which is MaxLLG's distinctive focus.
• Dassault Systèmes (CST Studio Suite): Dassault's CST Studio Suite is a leading 3D EM simulation tool used across RF, microwave, and antenna design. It is a broad incumbent comparable to MaxLLG in solving high-frequency EM problems but targets wider markets without magnetic-LLG specificity.
• COMSOL: COMSOL Multiphysics provides general-purpose multiphysics simulation including electromagnetic modules used by researchers and engineers. It competes in the broader EM/simulation category but lacks MaxLLG's specialised high-frequency magnetic-LLG coupling for metamaterial design.
• MathWorks (MATLAB): MathWorks' MATLAB and PDE toolboxes are widely used by researchers and engineers for EM simulation and prototyping, including via Python/Matlab interfaces that also integrate with MaxLLG. It is a broad incumbent offering general numerical computing rather than a dedicated magnetic metamaterial solver.
• Keysight Technologies (EMPro): Keysight's EMPro is a 3D EM simulation platform tightly coupled with its RF/microwave test-and-measurement instruments. It targets similar RF/microwave designers as MaxLLG but is bundled within Keysight's broader electronic-design ecosystem.
• Vector Fields / Simulia (Dassault): Vector Fields (now part of Dassault Simulia) historically produced Opera and other EM simulation software for scientific and industrial applications. It is comparable to MaxLLG as a specialist EM simulation tool now absorbed into a larger CAE incumbent's portfolio.
• Cadence (AWR Microwave Office / Clarity): Cadence offers AWR Microwave Office and the Clarity 3D EM solver for RF/microwave and high-speed electronic design. It addresses similar telecom, defense, and aerospace customer workflows as MaxLLG, but as part of a much larger EDA portfolio.

Direct peers

• Sonnet Software: Sonnet Software offers high-frequency EM analysis tools used for planar circuits, antennas, and microwave integrated circuits. It is a direct peer targeting similar RF/microwave engineers, though its planar-method focus differs from MaxLLG's 3D LLG-coupled approach.
• Remcom (XFdtd): Remcom provides XFdtd and other EM simulation tools for antenna, microwave, and electromagnetic compatibility analysis. It is a direct peer in the 3D EM simulation market, with comparable product scope though different solver underpinnings and without MaxLLG's LLG-coupled magnetic specialisation.
