À l'heure où tout le monde vibe code un B2B SaaS, cette équipe d'ingénieurs français, dropouts, construisent depuis 12 mois le prochain géant de la production d’acier (décarboné !) depuis Hong Kong. Et leurs résultats en 1 an sont sans précédent : ils viennent d'atteindre le stade symbolique des 1 tonne d'acier produit par mois. Pour que vous compreniez bien : parmi le Top 3 des meilleurs business angels internationaux en Seed d'après le classement américain Business Insider en 2025, 2 ont déjà investi plusieurs millions de $ dans leur entreprise. Quelle fierté de travailler depuis 6 ans avec Morgan et ses équipes... Quel privilège ! Si le sujet vous intrigue, je mets en relation sur demande.

Want steel on mars? Turns out it's also the best way to get steel on earth. @morganpelissier is building gigafactories for cheap, clean steel and already at nearly 1 ton per day of production!

@morganpelissier This is the way

every entrepreneur in this city is scared of "the perpetual rat race*". while they should be making ultra high purity iron and steel at 50% gross margin. not replaced by ai anytime soon *apparently this is what will happen to you if you don't make it before agi.

Electricity output is the single best proxy for industrial capacity

Factory back in production =

Ready to ship some sparkmate steel mini ingots

ok, back in the days @maxime_dsmn & I designed and built a very similar system for ariane group and the european space agency. we did that in 2019. it was a 1/10th scale prototype. they never pushed the project to full scale, I hope china will build it full scale

And just like that we are now a singapourean company

@zanehengsperger Yes! See @morganpelissier I'm not the only one

you can have all the AI nesting software in the world paper hard copy wins

pumped to announce that s̵h̵u̵n̵ ̵f̵a̵t̵ ̵m̵e̵t̵a̵l̵ ̵m̵a̵n̵u̵f̵a̵c̵t̵o̵r̵y̵ ̵ sparkmate hit 1 ton production scale last week. insanely proud of our team, we've done in less than a year, what others took 10 years to do... get f*cking ready

@morganpelissier Feeling energized now

had to bring him see his spiritual father @maxime_dsmn

these guys are building the future of steelmaking (and just came back from a boat trip)

The sheer size of this bulk cargo: those are not toys

Yes♥️

@ahmedshubber25 What type of steel products do you buy?

Lumina’s 2026 Goals: -$100M of excavation revenue -Dozer: fully certified & tested -18 dozers built (@ a $13M cost) -$10M of fabrication revenue to offset vehicle steel costs -Electric excavator program completed -Texas-based autonomy team built out -$20M EBITDA

The spark TV is now broadcasting all kinds of metalwork process 24/7

Despite a certain beauty, the fully electric steel mills of the future will be much more sexy

@winterrose Bravo! @spanarin 👀

the kids (9 & 8) asked for a computer so I made a quest for them: build an Apple 1 from scratch and get a MacBook Air. kit just arrrived, I’ll keep you posted
