Shared by Asterion Ventures

In May, Asterion Ventures gathered more than 80 European family offices at the Climate House in Paris for the first Family Catalyst Summit. In the two days that preceded it, a Learning Expedition brought together twenty families — from France, Italy, Belgium, the United States and Colombia — to map the European investment landscape together, room by room and conversation by conversation.

Two formats, one conviction: patient family capital is among the most powerful levers Europe has to finance its next generation of industrial champions. The continent does not lack science, talent or ambition. What it has lacked is capital willing to stay long enough for that ambition to compound.

The structural edge: capital that can wait

One remark from the Summit crystallised something we have argued for years. Gustave Gauquelin, Director of SISSE — the French State’s Strategic Economic Intelligence Service — put it without ornament:

“On the great transitions ahead, only families can take long-term risk. The State can hold duration, but it is risk-averse. Funds take risk, but on a short cycle. Families can do both.”
Gustave Gauquelin, Director, SISSE

The logic is simple and, once stated, hard to unsee. Decarbonisation and reindustrialisation do not fit inside a six-to-ten-year fund cycle. They demand both long duration and a tolerance for real technological risk — a pairing that has become rare. The State can hold duration but is structurally risk-averse. Conventional funds will take risk but are bound to a short return clock. Families, almost alone, can hold both at once. That is not a sentimental claim about values; it is a structural feature of how family capital is owned and governed.

Why now: these are no longer niche bets

Climate tech, deep tech and the reindustrialisation of Europe are not adjacent themes or moral side-bets. They are the foundational markets of the next twenty years — energy, materials, robotics, aerospace, quantum, the physical infrastructure on which everything else runs. What has changed recently is timing. Artificial intelligence is now compressing research-and-development cycles in these fields fast enough that breakthroughs which once sat beyond any investment horizon now fall within one. The scientific depth is in Europe. The founding teams are in Europe.

What had been missing was not the technology or the talent. It was a community of investors willing to bring capital, conviction and continuity at the same time — and to stay. That is precisely what the Family Catalyst Summit was built to assemble.

Stéphane Bourbier, Founding Partner of Asterion Ventures, framed the stakes directly:

“Impact used to mean accepting a slightly lower return for something that feels right. We say the opposite: this asset class will outperform the market, because the future giants of Europe will emerge from it now.”

More than money

The clearest signal of the two days came from no panel. It surfaced unprompted, across families that otherwise had little in common — French, Dutch, Belgian, Italian. The same sentence kept returning:

“We are ready to bring more than capital.”

Family offices are not asking to be passive investors who receive quarterly capital calls and an annual portfolio update. They want partnership in the literal sense: operational expertise, co-investment rights, a direct hand in building the companies they back. The capital is real — but it is the least scarce thing they offer.

Which inverts the usual question. The issue is no longer whether families will commit. It is whether the structures we build around them are worthy of what they are prepared to give.

A shared language across generations

Something else became visible at the Climate House: when impact and investment line up, a twenty-three-year-old and a grandparent end up in the same room, arguing about the same companies. Intergenerational transfer, so often treated as an obstacle, looked from the inside like the opportunity itself.

Many of the families present are in the middle of a transfer — of ownership, of conviction, of investment philosophy. Impact investing turns out to be a rare shared language across those generations, precisely because it connects financial return to something legible and concrete: an energy system, a material, a supply chain that no longer depends on a rival power.

For families early in that journey, the most valuable thing on offer is rarely a single fund commitment. It is access to a community that has already wrestled with the same questions, and a lead investor that has done the diligence and will stay through the hard quarters. Helping families make that transition is part of how we see our role.

In the families’ words

“It was genuinely interesting to learn more about the European VC scene and compare notes across geographies. The conversations made the case for staying close, whether in Paris, San Francisco or London.” 
— A family-office partner, San Francisco & London

“Two days of open, honest discussion, and a rare chance to compare notes with families facing the same questions. The organisation was excellent from start to finish.” 
— A participating family, Learning Expedition

“Our youngest generation is already engaged in philanthropy, but impact investing could be the ideal gateway to a more entrepreneurial, financial role within the family. You’ve built a team that makes people our age genuinely want to get involved.” 
— A NextGen member, European family group

What the next edition has to answer

Across two days, the families said, in effect, that they are ready. The work now sits with the rest of us: to design vehicles, co-investment rights and governance that match the seriousness of the offer. The next Family Catalyst Summit is planned for early 2027. The question it has to answer is the one the families themselves posed — whether the structures we build are worthy of the capital, and the conviction, they are willing to bring.
