World Labs

Category: Generative Media (Image / Video)

A spatial intelligence AI company building Large World Models (LWMs) that perceive, generate, reason, and interact with 3D worlds for creative media and robotics—generating persistent 3D environments and real-to-sim-to-real training worlds. World Labs was founded in 2023. The company is led by Fei-Fei Li. Based in San Francisco, United States. Team size: 40-50. Total funding raised: $1.23B. Latest round: Strategic Round ($1B, Feb 2026). Key investors include Andreessen Horowitz (a16z), New Enterprise Associates (NEA), Radical Ventures, Autodesk, NVIDIA (NVentures), AMD, Fidelity Management & Research Company, Emerson Collective, Sea Limited, Cisco Investments.

AMW Analysis

World Labs is a San Francisco-based computer vision startup founded in 2024 by Fei-Fei Li, developing Large World Models (LWMs) that perceive, generate, reason about, and interact with 3D environments. Its core product turns text prompts, images, videos, or 360° panoramas into editable, downloadable, spatially consistent 3D worlds exportable to industry-standard tools, positioning the company around reducing environment creation time from weeks to hours for use cases such as gaming, digital twins, and virtual production. The company commercialized this technology with the launch of Marble in November 2025, described as generating persistent, downloadable 3D environments rather than isolated assets, with spatial consistency as its central technical differentiator.

Since launch, funding activity has accelerated sharply: World Labs raised $1 billion in a strategic round completed in February 2026, at a reported $5 billion valuation, bringing total funding to $1.23 billion. Participants included Andreessen Horowitz, NEA, Radical Ventures, Autodesk, NVIDIA, AMD, Fidelity, Emerson Collective, Sea Limited, and Cisco Investments, with Autodesk contributing $200 million and taking on an advisory role. The round and its investor mix — spanning venture firms, chipmakers, and a design-software incumbent — reflect broader capital interest in the world-model category following Marble's commercial debut.

Value proposition

Transforms text, image, video, or 360° inputs into editable, downloadable, spatially consistent 3D worlds exportable to pro tools—and, via R2S2R, aligned simulation worlds that train and evaluate robot policies with far less real-world hardware time.

Products and solutions

Marble - Multimodal 3D world generation platform, World API - Public API for generating explorable 3D worlds, Chisel Editor - 3D layout tool for defining world structure, Studio - Edit and stitch worlds into larger environments, Spark 2.0 - Open-source streamable LoD Gaussian splatting for Three.js/web, Export Suite - Gaussian splats (.ply/.spz), triangle meshes (GLB), video exports, VR Integration - Native support for Vision Pro and Quest 3 headsets, R2S2R Engine (via SceniX) - Real-to-sim-to-real robotics simulation for policy training/evaluation

Unique value

Founded by Fei-Fei Li and leading experts; first commercial product to generate persistent, downloadable 3D worlds; multimodal input support with spatial consistency; integrates with professional tools.

Target customer

Game developers, film studios, VR/AR creators, robotics companies, architects, designers, and industrial/enterprise customers

Industries served

Gaming & Interactive Entertainment, Film & Visual Effects, Robotics & Autonomous Systems, Architecture & Interior Design, Virtual/Augmented Reality, Manufacturing & Industrial Simulation, Automotive & Autonomous Vehicles, Defense & Aerospace

Technology advantage

Combines Large World Models (LWMs) with 3D Gaussian Splatting (incl. Spark 2.0 streamable LoD) for photorealism and web efficiency; exportable assets for Unreal/Unity/Blender; R2S2R aligns generative worlds with robot dynamics for sim-to-real policy transfer.

How they differentiate

Persistent, downloadable 3D world generation with multimodal inputs and pro-tool exports; founded by Fei-Fei Li et al.; post-SceniX, closed-loop real-to-sim-to-real for robotics policy training/eval—bridging generative worlds and physical AI.
