OUR THESIS

A new generation of infrastructure.

A new generation of infrastructure.

We invest in European early-stage companies that make infrastructure more autonomous, capable, and resilient:
emerging leaders in the category we call InfraTech.

01

Autonomous

Systems that operate, decide, and adapt with minimal human intervention across complex physical environments.

02

Capable

Systems that push the physical and computational envelope of what infrastructure can perform.

03

Resilient

Systems that keep running when others fail, securing sovereignty against all threats.

"Infrastructure is no longer just a utility. It is moving closer to the end user, capturing more value and forming an integration moat between assets, data, and applications.

Across digital, energy, and industrial systems, we are proud to have unique industry access through
our partner and investor STRABAG. This underpins our commitment to actively support our founders beyond capital.”

- Ilja & Toba

THREE PILLARS

Where InfraTech is being built.

Where InfraTech is being built.

InfraTech doesn't sit on the side of the workflow. It sits in the middle, running factories, power systems, and data centers, and the control layer that runs them. The longer it runs, the harder it is to replace. We invest where that compounding is sharpest.

Digital

Compute and AI are the new infrastructure. Data center and communication technology, grid control software, and orchestration platforms.

Energy

Rebuilding how power is generated, stored, and balanced: power electronics and materials, software-defined grid hardware, and storage systems.

Industrial

Automation and intelligence for the physical economy, from manufacturing robotics to systems that keep critical assets running.

ABOUT THE FUND

Unique industrial access.

Unique industrial access.

STRABAG, one of Europe's largest infrastructure groups, is our investor and partner. This gives us and our founders direct industry access and domain expertise.

We invest purely financially, with no strategic mandate; any collaboration with STRABAG is optional and never a condition of our investment.
