What's the deal? BondstoneDealroom has a profile for this one. Try Dealroom →, a Lisbon-based private equity firm best known for its real estate portfolio, has launched a venture capital arm — Bondstone VenturesDealroom has a profile for this one. Try Dealroom → — and announced a target of raising €50 million for its first fund, Maxwell Technologies I.
The fund will target seed and early-stage deep tech startups across Southern Europe, writing initial cheques of between €500,000 and €1 million. A first close of around €10 million is expected during 2026.
The fund will focus on AI, quantum computing, computational biology, robotics, advanced materials, dual-use technologies, and space tech. It is supervised by Portugal's securities regulator, the CMVMDealroom has a profile for this one.

Why now? Bondstone founder and CEO Paulo LoureiroDealroom has a profile for this one. Try Dealroom →, alongside VC partner João Pedro SilvaDealroom has a profile for this one. Try Dealroom →, both with backgrounds in physics — argue Europe is at an inflection point where technology, economics, and geopolitics are converging around the theme of technological sovereignty. That argument has gained urgency as European governments and the European CommissionDealroom has a profile for this one.

Portugal fits the thesis. The country recently made its largest-ever contribution to the European Space AgencyDealroom has a profile for this one. Try Dealroom →, up 51% year-on-year. Bondstone is positioning itself to connect scientific talent in Portugal, Spain, and France — markets it describes as rich in researchers but underserved by specialist deep tech capital — with patient institutional money.
What could go wrong? The €50 million target is ambitious for a first-time VC fund from a real estate firm with no prior track record in venture. The first close target of €10 million underlines that the fundraising is still at an early stage. Institutional investors considering a first-time deep tech fund from a real estate manager will rightly scrutinise the team's ability to evaluate highly technical science-based startups — a very different discipline from property underwriting.
Deep tech also has characteristically long development cycles and high capital requirements beyond the seed stage. Writing €500,000 to €1 million cheques into companies that may need tens of millions to reach commercial scale means Bondstone Ventures will need strong co-investors and follow-on capital to protect its positions.
The signal: Bondstone's pivot reflects a wider pattern of non-traditional players entering European deep tech venture, drawn by geopolitical tailwinds and the European Commission's push for strategic autonomy. Southern Europe — historically underrepresented in venture capital relative to the concentration of scientific talent in its universities — is attracting increasing attention as a source of differentiated deal flow.
If Bondstone can leverage its real estate relationships to raise institutional capital and deploy it credibly into science-based startups, it could help bridge a genuine funding gap. But the firm is entering a space increasingly contested by experienced operators, and first-time fund managers face a steep credibility curve.
