DIG Ventures Closes $120M Fund III for Europe's AI Infrastructure

DIG Ventures has closed its third fund at $120 million, with a mandate to back AI infrastructure startups across Europe, Tech.eu reports.

The raise signals where at least one European investor believes the durable value in artificial intelligence now sits: not in headline-grabbing model developers, but in the underlying infrastructure layer that every company deploying AI must buy, build or rent. That category spans the compute, data, tooling and operational plumbing behind AI systems — the segment investors routinely describe as the picks and shovels of the technology cycle.

The $120 million figure matters for context. European seed and early-growth funds in this range can typically lead rounds from roughly $2 million to $15 million, positions consistent with a strategy of backing startups at the stage where infrastructure companies in Europe most often struggle for capital: after initial traction, before they become large, capital-intensive businesses.

The fund also marks a scaling point for DIG Ventures itself. A third fund, closed at $120 million, positions the firm to write more and larger checks than its earlier vehicles, and to support portfolio companies through subsequent rounds. In European venture, where funds frequently raise successor vehicles every three to four years, a Fund III close is generally read as evidence that limited partners were satisfied with the returns and deployment discipline of Funds I and II.

The geographic focus is deliberate. Europe's AI sector has produced a growing roster of infrastructure specialists — in areas such as data tooling, model deployment, energy-efficient compute and machine-learning operations — yet the continent's venture funding still skews toward application-layer companies. A fund explicitly reserved for AI infrastructure addresses that gap and competes with a small group of European investors making the same bet.

The timing works in the firm's favor. Corporate adoption of AI has pushed spending on the enabling layer to record levels, and enterprises increasingly prefer infrastructure providers that meet European data, privacy and sovereignty requirements. Startups building for those constraints have found willing buyers among the region's banks, manufacturers and public-sector bodies — demand that supports the revenue growth infrastructure investors look for.

DIG Ventures will now begin deploying Fund III. Its pace, check sizes and first announced deals will show how the firm defines AI infrastructure in practice — and how aggressively it intends to claim ground in one of Europe's most contested investment categories.
