Side-by-side comparison of AI visibility scores, market position, and capabilities
Dutch climate tech converting captured CO2 into building materials. Carbon mineralization 10M times faster than nature. $25M raised. World's first CO2-neutral bridge.
About
Paebbl is a Dutch climate tech company founded to commercialize carbon mineralization — a process that permanently converts captured CO2 into solid carbonate minerals used in construction materials. The company was founded on the scientific insight that natural rock weathering sequesters carbon dioxide over geological timescales, and that this chemistry can be accelerated by 10 million times in an industrial process to produce building materials with a net-negative carbon footprint. Paebbl's core technology converts waste CO2 streams into calcium and magnesium carbonates that can replace conventional aggregates, fillers, and binders in cement and concrete.\n\nThe company's primary product is the world's first commercially viable CO2-derived building material, produced by reacting captured carbon dioxide with alkaline industrial wastes such as steel slag and mine tailings. This dual-use approach both sequesters carbon and upcycles industrial waste, improving the economics of carbon removal compared to storage-only approaches. Paebbl's materials target the construction industry, one of the largest emitters of CO2 globally, and are designed to be drop-in compatible with existing concrete and cement manufacturing workflows.\n\nPaebbl raised $25M to scale its production technology and advance commercial partnerships with construction and industrial companies. The company is headquartered in the Netherlands and operates at the intersection of carbon capture utilization and storage (CCUS), circular materials, and green construction. As demand for verified carbon removal credits and low-carbon building materials accelerates, Paebbl is positioned as a rare company that can monetize carbon removal twice — through the building material itself and through associated carbon credits.

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.
