1/ New Lux quarterly letter to LPs...

Our theme? Tech, venture, global markets told in...

...Four parables of Four brothers
1 Prometheus
2 Menoetius
3 Epimetheus
4 AtlasImage
2/ The The Prometheus Promise––is Extending Human Limits what we call extensionalism

technology is not just augmenting our natural senses, but fundamentally extending and transforming them inImage
Image
3/ From sight, sound, touch, hearing and now…smell.

Technology extends our senses (“extensionalism”) with many Lux family co’ leading the way from

@physical_int + CTRL-Labs + Auris Surgical Robotics (touch)
@EikonTX + @Matterport (sight)
Chromatic (hearing)
@Osmo_Labs (smell)Image
4/The lever + pulley of antiquity gave way to the steam shovel + excavator

Even the modern state's quest for legibility––what James Scott (Seeing Like a State) saw as drive to make complex systems measurable + manageable––Lux cos extend sensed in sea + space @saildrone @planetImage
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet 5/ From genetically modified pigs with life-saving organs successfully transplanted into humans in dire need with no alternatives…

…to AI infrastructure with important 2nd order effects underway…. Image
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet 6/
Today's largest Al clusters use around 100,000 Nvidia H100 chips and consume roughly 100 megawatts of power. Next year's clusters will scale to 300,000-500,000 chips requiring nearly a gigawatt of power — about the consumption of a small city. Image
7/ we see 2 futures emerging

1 Distributed compute can eliminate need for massive monolithic clusters––as per our investment in @togethercompute

2 As industry fixates on bigger data centers + more powerful chips––Apple quietly has showing how to run models directly on devices w/ limited memoryImage
8/ America only has a handful of locations that can provide the gigawatt-scale power these massive clusters will require.

While we're bullish on the seeming resurgence of elemental energy - our rebrand of nuclear––abundant natural gas from the Texas Permian seems a wiser bet.Image
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet @togethercompute 9/ NYC's emergence as a major Al hub with 20 new unicorns in 2023 and 10 more already in 2024.

BUT…beneath the surface excitement though, we identified critical insights that are grounding our investment approach from the irrationality of the markets Image
10/ Epimetheus represents the danger of divorcing motivation from consequence. The benefits of the future start with tradeoffs of the present constrained by decisions of the past.

Higher for longer is our posture on the natural cost of capital, regardless of what the Fed does.Image
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet @togethercompute 11/

We have 4 main strategies for current market:

1 Lux Labs
2 Corporate Spin-offs (globally)
3 Tactical Global Opportunities
4 “Fixware” (aka maintenance) (globally) Image
12/ While techno-optimists focus on frothy greenshoots, they're missing the industry's further desertification: over 30% of 50,000 private cos are trapped in late-stage limbo while >730 unicorns are trapped in exit-less purgatory, with nearly 50% over 10yrs old + dragging down returns like sea-sinking anchors…Image
13/ We are particularly excited about Lux Labs

14/ Lux Labs formalizes our nearly twenty-year track record of transitioning breakthrough science from the laboratory to the marketplace.

We have successfully spun out or have been first investors behind de-risked technologies and teams from big tech. Examples include Osmo and Physical Intelligence from Google, Aeva (and another not yet disclosed) from Apple, and Evolutionary Scale from Meta. These unlock value by giving breakthrough teams and technologies the funds, freedom and focused entrepreneurial attention to thrive.Image
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet @togethercompute 15/
Globally we are particularly excited about Israel + Japan +UK
🇮🇱🇯🇵🇬🇧 Image
@physical_int @EikonTX @Matterport @Osmo_Labs @saildrone @planet @togethercompute 16/ Image
17/ As we look to the remainder of 2024 and beyond, several trends bear watching:

the acceleration of Al capabilities beyond language models into biology, chemistry and physical systems; the growing imperative for domestic manufacturing and supply-chain resilience; the continued convergence of commercial and defense technology; the evolution of experimental science through automation; and finally, the transformation of healthcare through sci-fi breakthroughs like xenotransplantation.

In the end, we return to where we started: compassionately competitive, motivated and mission-driven, helping to write the future, one breakthrough at a time.

We're betting on the impatient optimists who refuse to wait for permission to build the future.Image

1/ why Quantum is BULLSHIT

"paving a path towards potential future"

like saying: 'Working towards possibility of maybe a thing that might one day be a breakthrough if a breakthrough were to maybe occur'

Here I assemble just 2005 to 2015 annual headlines or this BULLSHIT
2/ I could start in the 90s. But let's just go thru 20yrs of BULLSHIT

2005... Image
3/ 2006... Image

1/ Revealing Lux's latest

a $101M launch of new cutting-edge biotech created from one the most important scientific breakthrus Lux has seen in many yrs!

NILO

control IMMUNE system 🦠
via NERVOUS system 🧠...

we stealth funded last yr before this NATURE paper got published👇Image
Image
2/ THE BIG IDEA?

Your brain has a direct hotline to your immune system.

Specific neurons in the vagus nerve detect inflammatory signals + then tell your brainstem to dial inflammation up or down.

When our team cut this connection immune responses went completely haywire!
3/ Here's HOW it works:

Think: biological thermostat for inflammation🌡️

Different vagal neurons respond to pro vs anti inflammatory cytokines (proteins that act as messengers in cell communication)

They relay this info to neurons––which then regulate the immune response...

1/ Apple researchers just dropped NEW foundation model on BEHAVIORAL data from wearables.

Forget raw sensors—think steps, heart variability, gait

Trained on 2.5B hours via 162K people

Predicts age, sex, pregnancy, sleep like a crystal ball. Image
2/ Their new foundation model (WBM) trained not on noisy low-level sensor data––but on derived behavioral metrics via wearables

Outperforms raw sensor models in predicting sleep, injury, & infection.

When combined CRUSH it—predicting pregnancy w/ >90% accuracy. Image
3/ Contrarian take––Transformers may be overkill for everything

head-to-head on wearable data (Mamba-2) beat Transformers for health prediction. Simpler tokenization also won.

Lesosn: data’s unique physics (irregular, noisy)+ ignore the loud signals to hear the whispers––edge is in the architectureImage

1/ New Lux quarterly LP letter––Q2 2025

theme: “Friction Frontier”

-Over 50% of small VCs will involuntarily exit as ~5 VCs are planning to voluntarily exit (IPO)

-Lux team has invested over half a billion dollars across 82 companies (new + existing) in the past few months… Image
Image
2/
-Zuck’s “ Poachapalooza 2025”

-L&A (License + Acquihire) is the new M&A

-the AI capex surge (5% of GDP) ~ fiber-optic + router binge of 2000 tech boom (5.2%) and short step below sheet-rock bonanza of 2005 housing bubble (6.7%).

-Open source vs Closed… Image
3/great irony in frenzy for ARTIFICIAL intelligence––what’s acquired isnt hardware but HUMAN intelligence

-frontier of agentic Al not defined by model size-but what we can verify

-99% reliable agent degrades to 60.5% after 50 sequential decision tasks––each error cascading like cracks in glassImage

1/ Beyond the hype + headlines

some eye-opening AI stats to consider

Today Mag 7 = 35% of US stock mkt value

NVDA = 19% of that––and 42% of NVDA revenue comes from just 5 Big Tech co's buying GPUs:

Meta, Amazon, Microsoft, Google, Tesla
2/At recent lunch with LP who put Lux in business I talked about shift from consensus cloud inference (GPUs + datacenters + power) to on-device inference (memory + batteries)...
3/ This valued LP talked about CAPEX:

Meta, AMZN, MSFT, GOOG TLSA spending $560B by EOY 2025

The total AI revenue from that spend? ~$35B

That's not great ~6% return

Apple just GaryMarcus'd LLM reasoning ability Image
2/ Apple tested today's "reasoning" AIs like Claude + DeepSeek which look smart—but when complexity rises, they collapse.

Not fail gracefully. Collapse completely.
3/ They found LLMs don't scale reasoning like humans do.

They think MORE up to a point…

Then they GIVE UP early, even when they have plenty of compute left.
