About Hangzhou Logarithmic Technology

Hangzhou Logarithmic Technology Co., Ltd., operating as Yuansuan Technology, is an industrial technology enterprise founded in 2017 and based in Hangzhou, China. The company has established itself by focusing on the convergence of simulation and cloud technologies to drive digital transformation in the industrial sector.

The core of Yuansuan's business is to enhance the digital research and development (R&D) processes for industrial products and to improve the digital operation and maintenance of facilities and equipment. It achieves this through a suite of products and services, including a cloud simulation platform based on high-performance computing (HPC), cloud-native industrial-grade Computer-Aided Engineering (CAE) systems, and specialized industrial apps. The company serves a diverse client base across sectors such as automobile transportation, energy and power, machinery manufacturing, and hydraulic and emergency response. Revenue is generated through project consultancy, engineering services, and providing access to its cloud-based simulation platforms and software, which can be deployed in public, private, or hybrid cloud environments.

Yuansuan's platform offers a one-stop solution that integrates the entire simulation workflow, from pre-processing and solver calculations to post-processing. This approach is designed to be agile and elastic, allowing engineers to access simulation resources on-demand, which can reduce hardware and system integration costs for clients by over 70%. The technology supports various simulation scenarios, including stiffness, strength, fatigue, computational fluid dynamics (CFD), crash analysis, and heat transfer. For example, the company has helped clients optimize product design, reduce physical experiment times, and predict waterlogging risks for flood control departments through numerical simulation. A notable partnership was formed with EDF in May 2020 to launch an industrial Computer-Aided Engineering SaaS platform based on EDF's open-source software for the Chinese market.

The company is privately held and venture capital-backed, having secured a Series C1 funding round in February 2024. Investors include prominent names such as CITIC Securities, CDH Investments, and Zhejiang Provincial Financial Holdings, signaling strong confidence in the company's trajectory.
