Investment thesis
Realyze Ventures focuses on the built world, backing European founders building technology and innovation for the real estate and construction sectors. Given that real estate accounts for roughly 40% of global CO2 emissions and a large share of energy consumption, the firm sees decarbonization, digitalization, and a shift toward serial prefabrication and industrialized production as the key industry drivers. It invests in startups tackling the biggest challenges in the built environment to deliver climate impact, greater process efficiency, and superior financial returns aligned with EU 2030 goals.
