Sketchfab is enabling multiplayer mode today with a new Sketchfab for Teams feature. The startup lets you share 3D models with other people in your company so that they can view, edit and download models. It could be particularly useful for companies working on augmented reality products, video games or even e-commerce websites with 3D configurators or visualizations.

Sketchfab has been working for years on a 3D model viewer for web browsers. It now works really well on both desktop and mobile. You can also import and export 3D models in many different file formats in order to reuse them in your favorite tool or engine — Sketchfab can convert files for you. That’s why 3D artists have been using the platform to share their work but also to sell 3D models, just like on a stock photography site.
