World Labs vs ElevenLabs
Side-by-side comparison of AI visibility scores, market position, and capabilities
Fei-Fei Li's spatial AI startup raised $1B in Feb 2026 (investors: AMD, Autodesk, NVIDIA); launched Marble generative world model; total funding ~$1.2B
About
World Labs is a spatial AI company founded in 2024 by Fei-Fei Li, the Stanford AI professor widely credited with creating ImageNet and advancing the deep learning revolution in computer vision. The company is building AI systems that understand, generate, and reason about three-dimensional physical spaces — a capability that sits at the foundation of robotics, augmented reality, autonomous vehicles, and spatial computing applications. World Labs' mission is to give AI a spatial understanding of the world comparable to how humans perceive and navigate physical environments.\n\nWorld Labs launched its first product, Marble, a generative world model capable of creating coherent, navigable 3D environments from images and text prompts. Marble represents a foundational capability for applications that require AI-generated spatial content at scale — from game world generation and architectural visualization to training data for robotics and autonomous systems. The company's research combines advances in neural radiance fields (NeRF), 3D Gaussian splatting, and large-scale generative modeling to produce spatial content with physical consistency and visual fidelity.\n\nWorld Labs raised $1B in February 2026 in a round backed by AMD, Autodesk, and NVIDIA — a strategic investor syndicate that signals the hardware and enterprise software industries' recognition that spatial AI is a foundational technology. Total funding reached approximately $1.2B, making World Labs one of the best-capitalized AI research companies in the spatial computing domain. The involvement of NVIDIA and AMD as investors reflects the enormous compute requirements of training 3D world models and the strategic importance of spatial AI to the broader semiconductor industry.
$500M Series D at $11B valuation (Feb 2026) — largest voice AI funding round ever. $330M ARR; 1M+ developers using the API. Enterprise customers: Deutsche Telekom, Revolut, Meta, Salesforce. Voices in 32 languages; real-time cloning from 1 second of audio.
About
ElevenLabs was founded in 2022 by Piotr Dabkowski and Mati Staniszewski, two former Google and Palantir engineers who set out to break the language barrier using AI voice technology. The company specializes in AI-powered voice synthesis, cloning, and dubbing, enabling developers and enterprises to generate human-quality speech in over 30 languages. Its core technology combines deep learning models trained on massive speech datasets to produce natural-sounding voices indistinguishable from real humans.\n\nElevenLabs offers a suite of products including its flagship text-to-speech API, voice cloning tools, and an AI dubbing platform that localizes video content while preserving the speaker's original voice. Its products target a broad audience—from indie developers building audio apps to large enterprises deploying voice interfaces at scale. Key differentiators include ultra-low latency streaming synthesis, fine-grained voice customization, and a growing library of pre-built AI voices across accents and styles.\n\nElevenLabs has grown rapidly, surpassing $330M in annualized revenue and serving over 1 million developers. Enterprise clients include Deutsche Telekom, Spotify, and leading media companies. In February 2026, the company closed a $500M Series D at an $11B valuation, cementing its position as the market leader in AI voice. Its APIs power podcasts, audiobooks, video games, and customer service bots worldwide, making ElevenLabs the default infrastructure layer for AI-generated audio.
