Zenithon Raises $10M for AI World Models
UK-based AI startup Zenithon has secured $10 million in funding to develop world models for extreme physics, targeting technologies such as fusion reactors, rockets, and semiconductor manufacturing. The round was backed by investors including BACKED, Lunar, Seraphim, MMC, and SOSV, with participation from founders and hyperscaler directors. The company aims to enable engineers to explore a million design points in the time it takes to simulate one, while learning from real-world experiments. Co-founded by Alex Higginbottom and Abetharan Antony, Zenithon brings together researchers in machine learning for physics. The funding will support recruitment and compute, allowing the company to release new models every three months and expand its team in San Francisco and across the US.
This funding round highlights growing investment in AI-driven simulation technologies, which could eventually impact adtech through more efficient modeling of complex systems, though the direct relevance to advertising is limited.

Yann LeCun's AMI Labs Secures $1.03B for AI Research
AMI Labs, an AI startup co-founded by Turing Award winner Yann LeCun after his departure from Meta, raised $1.03 billion at a $3.5 billion pre-money valuation to develop ‘world models’—AI that learns from real-world data rather than only language. Led by CEO Alexandre LeBrun, AMI positions itself as a research-first lab building on concepts such as JEPA (Joint Embedding Predictive Architecture). The round was co-led by Cathay Innovation, Greycroft, Hiro Capital, HV Capital and Bezos Expeditions and included strategic investors and angels (including Tim and Rosemary Berners-Lee, Mark Cuban and Eric Schmidt). The company plans multi-year research work, will publish papers and open-source code, and names Nabla as its first disclosed partner. AMI will prioritize compute and high-quality talent across Paris (headquarters), New York, Montreal and Singapore, and currently does not plan to generate revenue in the near term.
LeCun’s AMI Labs Raises €890M for World Model
Yann LeCun’s startup Advanced Machine Intelligence Labs (AMI Labs) raised €890 million this spring to develop a so‑called "world model" — an AI approach that encodes generalized, abstracted knowledge about objects, agents and interactions rather than only predicting text patterns. The t3n article explains that proponents see world models as a potential evolution beyond current large language models (LLMs) from companies like OpenAI, Google and Anthropic, because they could provide deeper real‑world understanding and reduce failure modes where models reproduce harmful or nonsensical examples from training data. The piece outlines differing definitions of "world model" across cognitive science, simulation and AI research, and notes both potential advantages and trade‑offs of the approach.

Zeit AI Raises €5M for Autonomous Data Engineering
Zeit AI, a Munich-based startup founded in 2024 by Palantir alumni Leopold von Waldthausen and Marvin Bornstein, has raised €4.3 million ($5 million) in a funding round. Investors include Y Combinator, University of Oxford's Seed Fund, Sequoia Capital Scout Fund, ACE Ventures, and Hasso Plattner VC. The company develops ZeitMind, an autonomous AI agent that connects ERP, CRM, and over 600 other systems to automate data engineering tasks for mid-sized European companies. ZeitMind cleans and structures data, builds analytics-ready applications, and offers traceable results with German data center hosting, providing affordable data engineering capabilities to businesses lacking specialized talent. The funding will be used to expand the team in Munich and London and reach more businesses across the European mid-market.
