Market Context / Industry Background
The launch comes amid increasing momentum for deeptech investment in Europe, driven by advances in AI, sustainability technologies, and scientific research. Governments and institutional investors are placing greater emphasis on supporting innovation ecosystems that can strengthen technological sovereignty and competitiveness, particularly in strategic sectors with long-term impact and industrial relevance globally today.
Southern Europe, in particular, has seen growing activity in early-stage funding, although access to capital for deeptech startups remains more limited compared to more mature ecosystems in Northern Europe and the United States. Funds such as Maxwell Technologies I are positioned to address this gap by providing targeted support at earlier stages of development, helping founders scale complex innovations more effectively.
At the same time, closer collaboration between academia and venture capital is becoming a defining feature of the sector, as complex technologies require both technical validation and long-term capital commitment, often involving multidisciplinary research teams and extended development timelines.
Founder / Investor Commentary
Founder and Chief Executive Officer Paulo Loureiro described the launch as a continuation of the firm’s broader investment strategy. He noted that Europe is experiencing a period shaped by economic shifts, technological acceleration, and geopolitical changes, creating conditions for new technology-driven companies to emerge.
Partner João Pedro Silva highlighted the strategic importance of expanding into venture capital, positioning the new division as a step toward deeper participation in Europe’s innovation ecosystem. He emphasized the firm’s combined expertise in finance and science as a differentiating factor when supporting founders developing complex technologies.
Growth Plans / Use Of Funds
The Maxwell Technologies I fund aims to raise €50 million from institutional investors and will be deployed across early-stage DeepTech companies in Europe. Bondstone Ventures plans to build a diversified portfolio across sectors such as AI, ClimateTech, and life sciences, with a focus on scalable and research-driven innovation.
In addition to capital investment, the firm intends to strengthen its network of academic and industry partnerships, supporting founders through access to expertise, talent, and strategic guidance. The team, consisting of around 20 professionals, brings experience across private equity, venture capital, and scientific disciplines.
The expansion into venture capital is expected to complement Bondstone’s existing real estate activities, which continue to focus on residential, logistics, hospitality, and mixed-use developments in Portugal.
