Physna

Physna, short for "Physical DNA," provides an enterprise platform that allows clients in sectors like aerospace, automotive, manufacturing, and defense to search, compare, and analyze their 3D model databases. This helps reduce design time, lower procurement costs by identifying duplicate parts, automate quality control, and protect intellectual property. The company's technology can analyze millions of models in seconds, identifying parts within complex assemblies and finding alternative components. Physna operates on a B2B SaaS subscription model, with customers including the U.S. Department of Defense.

In addition to its enterprise software, Physna operates Thangs.com, a free-to-use public geometric search engine and 3D model community. Launched in 2020, Thangs allows users to search for models using geometry, share designs, and collaborate on projects with version control features. It has grown rapidly, hosting millions of models and attracting a large user base of designers, engineers, and hobbyists. Thangs also offers monetization options for creators through subscriptions and features an "Instant AR" tool to view models in augmented reality. The company has raised a total of $86 million in funding from investors including Sequoia Capital, Tiger Global Management, GV (formerly Google Ventures), and Drive Capital.
