What World Labs does
World Labs Technologies, Inc. is a San Francisco-based spatial intelligence company founded in early 2024 by Fei-Fei Li, Justin Johnson, Christoph Lassner, and Ben Mildenhall. It builds Large World Models (LWMs), a family of proprietary multimodal AI systems that perceive, generate, reason about, and interact with three-dimensional environments, anchored on 3D Gaussian Splatting, Neural Radiance Fields, and learned rendering techniques. The commercial flagship is Marble, launched in November 2025, which generates spatially consistent, persistent, navigable 3D worlds from text, images, video, 360 panoramas, or coarse 3D layouts and exports them as Gaussian splats, meshes, or video. The platform is augmented by Spark, an open-source 3DGS renderer for the web (Spark 2.0 with Level-of-Detail streaming), and by RTFM, a research-preview real-time generative world model running on a single H100 GPU.
World Labs monetizes through a freemium and tiered subscription model on the Marble web app (free personal tier plus paid Standard, Pro, Max tiers topping out at $95/month), a Pay-As-You-Go developer API at platform.worldlabs.ai using Service Credits, and custom multi-year enterprise Order Forms with commits and sublicensing rights. Go-to-market blends product-led growth (self-serve Marble web app, Discord developer community, open-source Spark) with enterprise distribution via a strategic Autodesk advisory partnership (integrating into AutoCAD, Revit, Maya, Fusion) and an NVIDIA Isaac Sim co-marketed workflow for robotics simulation customers. Reported paying use cases span virtual film production, architectural design, and robotics training.
The company has raised approximately $1.23 billion across a September 2024 seed round ($230M at a $1B valuation), a November 2025 Cisco strategic investment via Convertible Preferred Stock, and a February 2026 $1B round at an approximately $5B valuation anchored by a $200M Autodesk investment with participation from AMD, NVIDIA, a16z, Emerson Collective, Fidelity, and Sea. It employs 11-50 people and operates globally subject to standard U.S. export controls and age-of-majority restrictions.

Revenue model
- Marble Subscription Tiers: Tiered monthly recurring subscriptions (e.g., Standard, Pro, Max) that allocate monthly Service Credits for use of Marble; unused credits expire at the end of each billing period and do not carry forward, with overage charges billed at next cycle.
- API Pay-As-You-Go: Usage-based API consumption billed via Service Credits purchased independently of subscriptions; includes minimum initial purchase, rate limiting, concurrency limits, and credit expiration within one year of purchase.
- Marble Free Tier: Free account access to Marble for personal, non-commercial use of generated outputs; provides top-of-funnel acquisition and usage data for AI Model training under World Labs' non-exclusive license.
- Top-Up Credits: One-time purchases of additional Service Credits beyond subscription allocations; remain valid for one year (Top-Up Period), carry over month-to-month, and are consumed after subscription-allocated credits are exhausted.
- Enterprise Order Form Licensing: Custom Order Forms for Paid Account Users and API integrations granting commercial rights to Outputs, sublicensing rights for downstream applications, and bespoke commitments/renewal terms with annual or multi-year cadences.
