What Quint does

Quint Corporation (株式会社くいんと) is a Japanese computer-aided engineering (CAE) software company founded in 1985, specializing in structural optimization and image-based structural analysis. The company sells a portfolio of six proprietary software products: OPTISHAPE-TS (flagship structural optimal design software with topology, shape, and bead optimization, with predecessor OPTISHAPE launched in 1989 as the world's first commercial topology optimization software); S-Generator (CAD model generation from optimization results); VOXELCON (CT/STL image-based structural analysis with homogenization and topology optimization via Level Set Method); AMDESS (multi-objective parameter optimization via the satisfying trade-off method); HiramekiWorks (SOLIDWORKS add-in for designers); and OPTISHAPE-ES (free educational version). Quint's core technology rests on proprietary mathematical methods developed over 40 years of continuous R&D, including the H1 Gradient Method (力法) for shape optimization developed in collaboration with the University of Michigan, and academic partnerships with researchers at University of Tokyo and Kyoto University.

Revenue model

1. Software License Sales (Structural Optimization CAE Software): Quint generates revenue primarily through the sale of perpetual software licenses and annual maintenance/support contracts for its suite of CAE products: OPTISHAPE-TS, S-Generator, VOXELCON, AMDESS, HiramekiWorks, and OPTISHAPE-ES. The company also offers commissioned analysis and development services (受託解析/開発) leveraging its products. Licensed through a proprietary license management system (くいんとライセンスシステム).
2. Commissioned Analysis and Development Services: Quint provides fee-based commissioned analysis and development services using its proprietary CAE software tools. Services include model correlation (モデルコリレーション) combining VOXELCON, AMDESS, and OPTISHAPE-TS to match simulation models with experimental vibration data. Serviced through dedicated inquiry forms.
