The Bau Ventures

grundwerk.ventures is a venture studio and early-stage investor backing the next generation of B2B startups transforming the built world. We invest in breakout companies at Series A and beyond, and co-create with founders before they’re on anyone’s radar. Our focus areas include Construction Tech, PropTech, Urban Tech, and Built Environment Innovation. We work with founders solving infrastructure-deep problems in construction, real estate, urban systems, and energy, people with domain edge, proprietary insights, and the drive to scale. What we bring goes beyond capital: real market access to global portfolios and infrastructure projects, deep operational support from pilot to scale, and unmatched domain expertise from decades at the core of how cities and systems are built. Whether you're ready to raise or just starting out, grundwerk.ventures is your partner into one of the world’s most resilient and under-innovated verticals.
