Spline
Browser-based 3D design platform with AI-assisted tools (Spline AI) for creating interactive 3D graphics, animations, and web experiences.

Spline was founded in 2020 by Alejandro León (CEO), Andrei Linkov, and Theresa Johansson, and is headquartered in San Francisco, California. The company builds a browser-based, collaborative 3D design tool that lets designers and developers create interactive 3D scenes, animations, and web/app experiences without traditional 3D software pipelines. Spline went through Y Combinator and has raised roughly $32 million in total funding, including a $15 million seed round led by Gradient Ventures (with participation from Y Combinator, Vercel CEO Guillermo Rauch, and Webflow CEO Vlad Magdalin) and a $10 million Series A led by Third Point Ventures, announced in July 2023. The company has since introduced Spline AI, a set of generative AI features for creating and editing 3D scenes and objects using text and image prompts, extending its no-code 3D design platform into AI-assisted content creation.
