Expanse Raises €4.5M for Predictive AI Infrastructure Platform
Expanse, a UK and US-based AI infrastructure company, has raised €4.5 million ($5.3 million) in a Seed funding round. The round was led by Crane Venture Partners with participation from PXN Ventures, AIP Seed, and angel investors including former DeepMind researchers. Expanse provides a platform that predicts AI workload resource requirements before execution, helping organizations optimize GPU utilization, reduce waste, and prevent failed jobs. The funding will be used to expand the engineering team, accelerate product development, and drive wider adoption. In one deployment, Expanse identified nearly $8 million in idle compute capacity in a single month. The investment is part of a broader trend in 2026 of funding AI compute efficiency and infrastructure startups.
Funding round for a niche AI infrastructure startup; relevant to AI and AdTech indirectly but not industry-shifting for advertising.

Prometheus Raises $12B to Build Physical AI Engineer
Prometheus, a physical-AI startup co-founded by Jeff Bezos and Vik Bajaj, announced a $12 billion funding round that values the company at $41 billion. The raise was led by Bezos and included institutional investors such as JPMorgan Chase, Goldman Sachs and BlackRock. Prometheus previously raised $6.2 billion at launch late last year. The company says it is building an "artificial general engineer" — software to automate design and manufacturing of complex physical systems — and will direct a large portion of the new capital toward significant compute needs. Prometheus employs about 150 people across San Francisco, London and Zurich. Bezos said productivity gains from the technology could create what he terms "labor scarcity," a view that contrasts with other industry predictions about AI-driven job losses.
