Three things could be done to improve Europe's competitiveness. Only one can be done fast.

The military has always been the earliest adopter of new tech. Dirk Singer noted that today it’s also one of the biggest investors in e-fuels — not for climate goals, but for energy security. Like solar panels in the 1990s, disruption often starts on the battlefield.

I’ve seen this before—in Russia. Decisions made not for policy, not for strategy, but for unchecked power. Now I see this playing out in...

Airbus showed Europe can beat giants like Boeing through distributed collaboration. Could batteries follow the same path—moving from vertically integrated gigafactories to networks of “partners in success”?

I stumbled across Martin Gallardo’s post and decided that it would be worthwhile to rewrite my comment into a full post. The consulting...

Crossing one valley of death is hard enough for any startup. For aviation startups, there are three!

A surprising revival of boring business amid the tech hype

Climate VC funding fell more than 3x from its peak in 2021

Michael Liebreich’s recent provocation on the Pragmatic Climate Reset raises many important points. One that stood out to me is that the climate movement has lost credibility by clinging to maximalist narratives while failing to deliver practical benefits.

Cleantech startups usually sell to mature industries, and these don't like new stuff. How can founders overcome change inertia? Ports, especially municipally owned ones, are notorious for resisting any change to how they operate. Here is a story from Polina Vasilenko on how to sell floating solar to municipal ports.

Latest data on clean energy VC investments. Are we seen new bubble emerging?

What is the future of electric mobility?

How diverse teams are really built.

What founders sometimes fail to realise is that as you scale up, you will spend less and less time working on your product and more and more time with your investors.

Two different points of view on climate investment. Both wrong.

Why pay more to achieve less? Really, why? Yet, you see this everywhere in climatetech. How come? A reduction in man-made CO2 emissions...

Cleantech scaleup climate impact assessment framework.

The humble transformer is at the heart of the electric grid. And for decades, it’s been a tailor-made marvel. Engineers loved the craft,...

My full breakdown is now live: What’s working, what’s missing, and what scaleups, especially in cleantech and manufacturing, can do today without waiting for Brussels.
