Company Overview
About Spline
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.
Business Model & Competitive Advantage
Spline's 3D design environment creates the Figma equivalent for interactive 3D: designers work in a browser-based scene editor (adding 3D objects, applying materials and lighting, defining animation curves and interactive behaviors) and export embeddable 3D scenes that render in any web browser through a Spline Viewer JavaScript library — no WebGL expertise required from the team embedding the 3D element. The real-time collaboration features (multiple designers working simultaneously in the same 3D scene, with cursor presence and live change sync) bring the Figma-style multiplayer design experience to 3D content creation. The Android support (added August 2024) extends Spline beyond browser and iOS deployment to native Android app integration. Spline's game development features (physics simulation, interactive event triggers, collision detection) enable the creation of simple browser-based game elements and product configurators that use 3D interaction as an engagement mechanic.
Competitive Landscape 2025–2026
In 2025, Spline competes in the 3D design tools, interactive web content, and no-code 3D creation market with Jitter (motion design for UI, $4M raised), Rive (interactive animation, $30M raised), and Blender (open-source 3D creation, free) for designer and developer 3D content creation workflow adoption. Spline's position as the accessible, browser-based 3D design tool (versus Blender's steep learning curve and Cinema 4D's enterprise pricing) has made it the default choice for product designers and web teams adding 3D to digital products — the same "democratization" thesis that drove Figma's adoption over Adobe XD. Third Point Ventures' Series A and Gradient Ventures (Google's AI-focused fund) participation reflect conviction in interactive 3D becoming standard in premium web and app design. The 2025 strategy focuses on growing the AI 3D generation capabilities (generating 3D objects and scenes from text prompts), building the enterprise design system integration (Figma-to-Spline asset handoff for design teams using both 2D and 3D tools), and expanding the game development features for the indie game and interactive experience market.
