SF/Chile YC W21 browser-based collaborative 3D design platform at $32M total ($16M Third Point/Gradient Series A Jun 2024) and $55M valuation; no-code 3D for web/app/game competing with Rive and Blender for interactive 3D content creation.
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.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
About
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
