Excited to officially announce the launch of Pax Fund I, a $50M early stage vehicle dedicated to founders transforming the foundational categories of society.ย ๐บ๐ธ๐
Wrote a bit about my journey and the thinking behind Pax below:

a two-year-old mining company has raised $400M. @a16z, @khoslaventures and the CIA's venture fund are all on the cap table.
@jclozano9897 co-founded @MarianaMinerals with @tbc415 and @baker_tilney, two friends from stanford. it's now worth $1.6B. they buy mines after the market gives up on them, then run them with software and AI.
i asked him how you actually buy a mine, why AI's real bottleneck is metal, and whether he'd hire me for being good at claude code.
nontechnical, episode 3.
00:00 $400M and the CIA's venture fund
02:19 you can just buy a mine
04:41 2 years, $400M, $1.6B
08:58 cold emailing VCs vs. their first check
13:46 when to buy a mine (right after the market gives up)
19:54 every mining truck is a robot without a brain
25:08 everything human-made is grown or mined
26:15 the cheapest AI company wins
28:31 AI's real bottleneck is metal
30:55 america doesn't have enough miners
33:27 space mining and asteroids
43:13 how a $1.6B founder hires
46:17 would he hire me for claude code?
48:43 "slop cannon"

Woo! 3 for 3 baby! Today, the @USNavy selected Radiant to power critical infrastructure at Crane. There is not an organization in the world with more experience in nuclear power than the U.S. Navy. We are honored to be selected by the U.S. Navy for this important work and we thank the Navy and the Armyโs Dr. Waksman for their confidence in Radiant to deliver reliable, resilient nuclear power wherever their mission demands.
Our mission of Atoms for Prosperity is today strengthened by the support of the Navy and the State of Indiana. LETโS BUILD REACTORS!
The @USNavy has selected Radiant to deploy our Kaleidos microreactor at Naval Weapons Station Crane, Indiana.
With this selection, Radiant is now the only nuclear microreactor company with partnerships across the Army, Navy and Air Force.
The Navy has more than 70 years of safe reactor operations. It wrote the playbook on reactor safety. Earning its confidence is powerful independent validation of Kaleidos.
This milestone moves us closer to our goal: reliable, resilient nuclear power wherever the mission demands. Through our work with all three branches, weโre building a clear path from military deployment to nuclear energy at scale for government and commercial customers.

Big day for @pax_ventures companies announcing rounds, thrilled to be part of the @AirSpaceIntel journey.
One of the most important and relentless companies out there, working hard to power our critical institutions (and making a big dent in aviation!) โ๏ธ
Our mandate at Pax is quite simple: we back founders building a future where technology strengthens America at its foundations and drives prosperity for everyone.
Itโs hard to think of a more vital (and broken) pillar of society than housing. This country was built, in part, on the promise that you could own a piece of it. Housing underpins everything from family formation to middle-class wealth creation. A mortgage is the largest, cheapest loan most Americans will ever get, and theyโre being locked out of it.
Startups have spent years trying to tackle housing and every one has failed. Not necessarily because of bad ideas, but because of structural roadblocks like permitting, fragmented markets, mismatched capital, etc.
Some of those barriers are finally coming down, and a new wave of startups like @americanhousing, @buildwithcuby, @ReframeSystems, @Permitflow and other are building around the categoryโs failure modes. I wrote up some thoughts on whether this might be the moment homebuilding startups finally work. ๐ก

Replying to @MichelleVolz @pax_ventures
We love Pax! Thanks for supporting us at the seed, @MichelleVolz!
Arda is ripping and recruiting some of the best talent out there. If youโre looking to work on hard modern problems around scaling American manufacturing with an ELITE team, they are hiring a ton in SF!
@pax_ventures is a proud supporter ๐
We started Arda in 2025 to speed up American manufacturing. We have spent the last year building with Anduril as our design partner. Today we are launching the company publicly on CNBC and announcing our Series A: $160M at a $1.5B valuation.
Our platform helps manufacturers design and operate manual assembly lines, putting designs into production faster now. Next we'll build automated lines that can be reconfigured as quickly as human workers, letting America make products that now require armies of workers in Asia.
Iโd like to believe that United did this for me ๐ฐ๏ธ
How can the internet on @united flights be consistently so bad? Can we please get Starlink on every flight already
Worth the read (even if written by Marines ๐).
@scott_sv and Josh are two of the best operators I've come across in defense. And Forterra is a great example of doing vs. being - probably why they dominate the ground autonomy space today. Endlessly grateful to have Scott as a venture partner for Pax.
Over the last 4 years, lots of people have asked me "why Forterra" or "why do you care about the ground domain so much."
Well, we came from the infantry and despite the hype around drones/maritime, wars are still decided on the ground. It is the dirtiest, most dangerous layer of warfare where human beings have always had to be the blunting force.
So @JoshAraujo and I wrote a paper about it (yes, ex-Marines can write.)

Huge for securing our critical infrastructure ๐ค
Method and Palantir are announcing the Cardinal Program: a consortium of AI, infrastructure, and security partners to strengthen national cyber resilience.
Americaโs municipalities, water and power utilities, and critical infrastructure operators now face cyber adversaries armed with AI.
Their defenders should not have to stand alone.
Cardinal will provide select municipalities, utilities, and critical infrastructure operators with free, opt-in, continuous autonomous security assessments - with expert operators and human oversight.
If your organization protects critical systems or public services, we want to hear from you.
Let the lithium flow
Today we're celebrating the first concrete pour at Lithium One! The foundation is underway in advance of going vertical next month.

Bringing cyber resilience to Space.
Method is proud to announce a $30M STRATFI award (Strategic Funding Increase) to equip the U.S. Space Force with the autonomous cyber infrastructure it needs to win in a contested space environment.
Weโre looking for the countryโs best engineers and cyber operators to join us in support of this mission.
