I've had the privilege of being a part of this team for over 5 years, and the deep partnerships that we form with the breathtaking founders we meet continue to awe me. Politics may change around us; science remains the core hope for us all. And we get to keep building that hope.

[Lux Capital @Lux_Capital]

We started Lux in 2000 with a simple conviction: the biggest opportunities lie at the frontier of science and technology that others find too hard, too early, or too confusing. Twenty-five years later, that conviction hasn't changed. What has changed is that the world has caught on.

Now compute, automation, and biology have matured into scalable engineering disciplines, and what was once fringe "deep tech" has become essential infrastructure. New talent, new tools, and new industrial capacity now exist to turn the most cutting-edge technology across the physical, computational, and life sciences into enduring businesses.

For these businesses and founders to become category-defining winners, they need meaningful capital and conviction. That is why we are especially excited to announce our largest fund to date, Lux Ventures IX, a $1.5B commitment to investing in the people turning sci-fi into sci-fact.

Today entire sectors of aerospace, biotech, defense, industrials, transportation and beyond are being reinvented by a new generation of brilliantly ambitious, often irreverent, scientists and engineers. And while markets have changed and capital reshapes around fewer companies and larger checks, our focus on the craft remains constant.

That focus matters because science doesn’t scale itself. The path from a result in the lab, only known to a few, to something durable the entire world will use requires a different kind of partnership. One that deploys the first $100K and the last $100M, that stays through the full arc of company-building, that mobilizes a powerful network of kinetic like-minded founders, and that treats capital as a tool rather than the product.

Forty-four people at Lux now manage $7B, still operating with the same discipline and purpose we had on day one. We find and fund founders others have overlooked, back conviction over consensus, and build alongside these rebels of science and tech at every stage.

We’re grateful to our valued LPs who've partnered with us through multiple cycles, and to the founders who trust us with their life's work. The mission continues, with even greater intensity and momentum.

Stunning array of thinkers, creators, and builders helping the world understand what we SHOULD do with AI, not just what we CAN do.

[Grace Isford @graceisford]

Last Wednesday, @Lux_Capital hosted its 3rd AI Summit in NYC - bringing together nearly 300 top CEOs, researchers, builders & creatives in one room 🚀

[sirubi @sirubi]

AI is indeed reshaping healthcare. Anyone who doubts it will be left behind. @deenashakir's insights tell a powerful story.

[Lux Capital @Lux_Capital]

1/ Our own @deenashakir rocked the stage today at the @statnews Breakthrough Summit with @mariojoze, @morgancheatham of @BreyerCap, and Lynne Chou O'Keefe of @definevc, discussing AI's revolutionary impact on healthcare. Check out Deena's top insights + a clip of her panel👇

[sirubi @sirubi]

This isn't a choice; it's a necessity that benefits all of us.

BIG NEWS from Lux🚨…

American scientists––and those we attract to America🇺🇸––are what have helped make America not just great but absolutely + relatively EXCEPTIONAL.

We CANNOT cede scientific supremacy to China.
We don’t need talk, we need action…

[sirubi @sirubi]

When funding for science gets cut, America's future takes the hit. Lux's $100M Science Helpline bridges the gap between brilliant minds and breakthrough ventures.

[Lux Capital @Lux_Capital]

2/ Here's the truth: The CCP's '2035 Science & Technology Vision' boldly asserts that 'original innovation is the sharpest blade.' They're not just talking the talk; they're backing this vision with substantial subsidies, strategic talent visas, and guaranteed procurement.

[sirubi @sirubi]

Let's save American science and scientists. It's good for everyone.

[Lux Capital @Lux_Capital]

1/ We're dedicating $100M to support American scientists facing funding cuts through the Lux Science Helpline, an expansion of our Lux Labs program. To compete in the future, innovation must be funded 🧪💡

[sirubi @sirubi]

Science should be our unifying belief to build and maintain American competitiveness.

[Lux Capital @Lux_Capital]

1/ Ever wonder how tech innovation & global security are more intertwined than ever? As leaders convene at Hill & Valley this week, our @wolfejosh & @brett_mcgurk make the crucial case for "Sci-Tech Diplomacy". More 👇

Israel has concluded that Ariel and Kfir Bibas were barbarically murdered by terrorists in captivity in November 2023 and that Hamas did not return the body of Shiri Babas as promised, thereby violating the ceasefire. Meanwhile, Israel has been the target of attempted terror attacks, with multiple explosive devices planted on multiple buses.

Those who insist that Israel stop defending itself in the face of genocidal terror are asking the world’s only Jewish State to sign a suicide pact that no other nation-state, including our own, would ever sign.

Great to be w/@MorganLBrennan + @jonfortt on @cnbc

we riff on
-US vs China
-TikTok vs Trump
-Anduril + Saildrone
-Open Source vs Closed AI
-Deepseek vs Open AI + Anthropic...

Dr. Martin Luther King Jr. would have spoken out against 10/7 because he understood that there is nothing morally neutral about silence. Silence is not amoral but immoral. It is a form of complicity.

Dr. King once said: “In the end, we will remember not the words of our enemies but the silence of our friends.”

Introducing ESM Cambrian.

Unsupervised learning can invert biology at scale to reveal the hidden structure of the natural world.

We’ve scaled up compute and data to train a new generation of protein language models. ESM C defines a new state of the art for protein representation learning.

[sirubi @sirubi]

An amazing moment in the march towards the future of an amazing Lux Capital family company!

[Alex Wiltschko @awiltschko]

Well, we actually did it. We digitized scent. A fresh summer plum was the first fruit and scent to be fully digitized and reprinted with no human intervention. It smells great.

Holy moly, I’m still processing the magnitude of what we’ve done. And yet, it feels like as we cross this finish line we are instantly at a new starting line. I’ll have more to share about what’s in store that we’re building on top of this.

A huge HUGE congrats to the entire team across scientific, engineering, operational, and creative disciplines. It takes a village named Osmo to do this.

I don’t know if this is embarrassing, but I carry the plum scent with me a lot of places and smell it constantly. It makes me smile.

I’m curious, if y’all want to smell it? If we made a limited release fragrance of the first teleported scent and dedicated the proceeds to science, would you want it?

[Josh Wolfe @wolfejosh]

INSANE 🤯
Lux family co @Osmo_Labs...
just TELEPORTED the first scent!

[Lux Capital @Lux_Capital]

6/ We're not replacing our traditional startup investing - that's still our bread & butter.

But some ideas need a different path. Some breakthroughs need a builder, not just a backer.

That's where Lux Labs coms in 🎯 let's go 🚀

[Lux Capital @Lux_Capital]

5/ Now we're doubling down. From ocean depths to outer space, from techbio to AI - we're hunting for ideas that can reshape our world 🌎
