Loom Ventures is a Vienna-based early-stage corporate venture fund launched in May 2026 by STRABAG, one of Europe's largest infrastructure and construction groups. The fund is operated through STRABAG Venture Capital GmbH, a wholly-owned independent subsidiary endowed with ~$52.8M USD (€48M) in initial share capital, and is positioned as a purely financial investor with no strategic mandate, an unusually founder-friendly structure for a corporate vehicle. The fund targets European InfraTech.
Loom Ventures backs early-stage European companies building at the intersection of hard technology and physical infrastructure.
Core areas include industrial AI and automation, sensing and industrial data platforms, enterprise AI for operational environments, secure compute, energy transition software and hardware, and physical AI systems for construction and civil engineering.
The fund targets companies whose technology sits inside the workflow, running factories, power systems, and data centres, rather than adjacent to it, creating compounding integration moats over time.
Loom Ventures launched with ~$110M USD (€100M) in committed capital in May 2026. Initial ticket sizes are ~$1.1M–$5.5M USD (€1M–€5M) at Seed and Series A. The fund is Europe-focused. No portfolio companies have been named at launch; the fund is in active sourcing.
