Investors have discovered jet turbine blades, which is a bit like discovering water. The blades spin at temperatures that would melt most metals, so the people making them have spent decades doing the hard part quietly. Now the money has noticed.
The source material says the blades are ‘extremely difficult to make.’ That is the most honest sentence anyone has written about a fundraising pitch this year. Difficult is the whole point. Difficult is what a manufacturing business looks like when it is not a slide deck.
A turbine blade is a single-crystal superalloy, cast and cooled with precision that takes years to master, and it has to survive a furnace while spinning fast enough to tear itself apart. Physics does not care about your seed round. It cares about grain structure.
So why the rush? Because a company that makes something hard, that customers cannot easily replace, is worth more than a chatbot with a gradient logo. Nobody has ever been fired for backing a company that holds the only qualified supplier list. Somebody will now call this a deep tech thesis and charge a management fee for it.
The blockchain comparison is unfair to blockchain. At least blockchain could be explained to a dinner guest in under ten minutes, and it never pretended to be a material science problem. The blades, meanwhile, are real and hot and slightly terrifying.
The venture firms will claim they are betting on the future of aerospace. They are betting that nobody reads the part where the engine has to survive.
