What Astraea Software does

Astraea Software Co., Ltd. is a privately held, founder-owned Japanese software company founded on April 2, 2020, by Kiyofumi Shijo, headquartered in Toshima City, Tokyo. The company researches and develops software-based 3D AI models, deep learning, CAE (Computer-Aided Engineering), and cloud technology solutions, with the stated mission of bringing AI and CAE capabilities to manufacturing firms — particularly small and medium enterprises (SMEs) and sole proprietors who cannot afford traditional high-performance computing CAE infrastructure. The company's core technical proposition is the direct application of AI to 3D shape data (mesh, point cloud) using a proprietary 3D shape convolution approach, avoiding the information loss and dimensionality limitations of converting 3D data to 2D images.

The company's product portfolio is the Aries series, comprising nine products that span the engineering design chain: 3D Surrogate Model (AI replacement for traditional FEM/CFD simulation), PINNs AI (physics-informed neural networks combining data-driven and physics-based simulation), 3D Synthesis (generative shape creation via VAE/GAN/Diffusion), 3D Matching (similarity search in latent space), 3D Classification (shape categorization up to 99.5% certainty), Inverse Design (target-performance-to-geometry), 3D Shape Optimization, 3D Topology Optimization, and Surface Matching. Underlying technologies include CNNs, GCNs, Transformers, VAEs, GANs, Diffusion Models, and PINNs, with custom extensions built on top of NVIDIA Modulus. A WebAPI delivery layer allows embedding of AI functions into customer applications.

Astraea monetizes through four streams: (1) cloud-based subscription (pay-per-use) for the Aries product series; (2) custom software and AI model development projects built on customer design data; (3) educational seminars on CAE and AI; and (4) consulting engagements provided by experienced engineers. Go-to-market is sales-led and enterprise-field-sales oriented, targeting CAD/CAM/CAE users in automotive, machinery, and electrical/electronics manufacturing, supplemented by interactive demo sites that allow prospects to test capabilities before purchase. The company operates with no disclosed external funding and minimal registered capital (10M JPY), and revenue is not publicly disclosed. Advisors include faculty from Chuo University and Kindai University in computational physics and mechanical engineering.

Core offering

Astraea Software develops and sells the Aries product series of 3D AI software for manufacturing and engineering workflows. Its products deliver 3D shape classification, generative shape synthesis, similarity matching, AI-driven surrogate simulation, physics-informed neural network modeling, and inverse design/t topology optimization directly on 3D mesh data. The software is delivered via cloud subscription, WebAPIs, and custom development projects for CAD/CAM/CAE users.

Product overview

Astraea Software offers the Aries product series - a comprehensive suite of 3D AI products for manufacturing and engineering applications. The portfolio consists of 9 core products centered around 3D shape recognition, generation, and simulation: Aries 3D Surrogate Model (AI-based simulation replacement), Aries PINNs AI (physics-informed neural networks), Aries 3D Synthesis (generative design), Aries 3D Matching (similarity analysis), Aries 3D Classification (shape categorization), Aries 3D Inverse Analysis/Inverse Design (target-to-geometry generation), Aries 3D Shape Optimization (geometry refinement), Aries 3D Topology Optimization (material distribution optimization), and Aries Surface Matching (logical surface comparison). The products work with 3D CAD data (STL, OBJ formats) and are designed to integrate with engineering workflows focusing on CAD, CAM, and CAE processes.
