About
Spline is a Santiago, Chile-founded (now San Francisco-based) collaborative web 3D design platform — backed by Y Combinator (W21) with $32 million in total funding including a $16 million Series A in June 2024 led by Third Point Ventures with participation from First Round Capital, Gradient Ventures (Google's AI fund), and YC — providing designers and developers with a browser-based 3D design tool for creating interactive 3D experiences, game elements, product configurators, and motion graphics without writing three.js or WebGL code. Founded in 2020 and reaching a $55 million valuation in July 2023, Spline serves the growing community of web designers who want to incorporate 3D interactive elements (spinning product models, 3D landing page heroes, animated 3D icons) into websites and apps through a no-code visual editor with real-time collaboration.
Mux is the video API platform powering Vimeo, Robinhood, CBS, and TED with streaming infrastructure and analytics, generating $46M revenue in 2024 and valued at $1B+.
About
Mux is a video infrastructure company that provides APIs for developers to build streaming video experiences without managing the complex encoding, delivery, and analytics infrastructure that professional video requires. Founded in 2015 by Jon Dahl, Steve Heffernan, Matthew McClure, and Adam Brown—the team behind video.js, the most popular open-source HTML5 video player—Mux brought deep video expertise to the API-first approach that companies like Twilio and Stripe had proven for communications and payments.
