Profile

Bondstone is a private equity and venture capital firm based in Lisbon, founded by Paulo Loureiro, an ex-Morgan Stanley executive director with a background in physics. The firm is uniquely positioned with a team that combines both scientific and financial expertise. This technical team approach sets Bondstone apart, enabling them to efficiently evaluate deeptech investments, which are often complex and require a detailed understanding of scientific concepts.

Bondstone invests in seed and early-stage companies within the deeptech sector, focusing on sub-sectors like artificial intelligence, computational biology, climatetech, and enabling technologies. Their investment strategy is primarily directed at Southern Europe but also extends to broader Europe selectively. The fund, Maxwell Technologies I, is their first venture capital vehicle, amounting to €50 million, aimed at bridging the funding gap in Southern Europe's deeptech ecosystem.

Notable investments of Bondstone include ventures in sectors such as AI and climatetech, although specific portfolio companies have not been publicly detailed. The firm's expansive real estate operation manages assets across Portugal, serving various projects, including residential and mixed-use developments.
