PropTech1 Ventures (PT1) is an independent early-stage venture capital fund founded in 2018 with offices in Berlin and London. As part of the ERIC Group platform and the ERIC Opportunity Club, PT1 draws on a network of real estate companies, banks, pension funds and entrepreneurs. After an oversubscribed €50 million debut fund, PT1 closed its second fund’s first round at €44 million in early 2023. The team of investors, entrepreneurs and sector experts works closely with founders to guide product development and market expansion across Europe.
PT1 focuses on pre-seed and seed rounds, deploying initial investments between €300,000 and €4 million and reserving capital for follow-on rounds. The firm seeks ventures that tackle challenges in real estate technologies, energy transition, infrastructure resilience and climate adaptation. Investments target scalable solutions for energy-efficient buildings, next-generation risk assessment tools and systems that strengthen the built environment against climate impacts. PT1 often co-invests with other venture capital firms and provides portfolio companies with market access and technical advice.
A key pillar of PT1’s portfolio is clean technology and battery systems. The fund backed Voltfang’s €15 million round to build Europe’s largest second-life battery factory and led a €7 million seed round for Terra One’s AI-driven large-scale storage solutions. Other notable investments include Ecoworks, which upgrades building envelopes for higher energy performance, and NeoCarbon, a company developing direct air capture methods. These investments underscore PT1’s interest in energy storage, circular battery use and carbon removal. They reflect PT1’s belief that the built environment is central to a low-carbon economy and that energy storage and circular systems will play a growing role in future infrastructure.
