Eleven years ago we started @EclipseVentures and bet everything on atoms. Rockets, robots, chips, factories, power systems, defense. The things civilization actually runs on.

Today, we're announcing $1.3B in new capital to keep building.

The physical world is overdue for transformation. Transportation runs on systems designed decades ago. The energy grid cannot keep up with demand. Healthcare depends on manual procedures that don't scale. Defense development moves at a fraction of the speed threats evolve. These are not software problems. They are full stack engineering and operations problems, and they have been underinvested in for a generation.

But there has never been a better moment to solve them. The best engineers are leaving big tech to build in the physical world. AI is compressing timelines from years to quarters. Policy is aligned. And customers are not waiting — the DoD, the hyperscalers, hospitals, and the Fortune 500 are all desperate for technology that makes physical systems smarter, faster, and more resilient. Talent, capital, technology, policy, and demand are all converging at once.

This is our moment 🇺🇸

We built Eclipse for this exact moment and in doing so, we launched a movement. Today that movement is 100 companies strong (and growing!). These companies supply each other, share customers, and help solve each other's hardest problems. Propulsion systems powering orbital defense. Modern supply chain infrastructure moving the worlds goods. Autonomous vehicles on three continents. Surgical robots performing procedures that used to require the world's best hands. Cloud hardware powering the AI revolution built on American soil. That's not a fund. That's an economy — an Eclipse Economy.

The door is open to rebuild the physical infrastructure of the country. We intend to run through it.

The @oxidecomputer journey is still in the early innings. Always fun to hear @bcantrill share a stories from the first few years.

In particular I will always treasure the board meetings with Pierre. Education of a lifetime.

Oxide just raised $445M at a $6B valuation.

@bcantrill and @sdtuck started @oxidecomputer to build the computers the hyperscalers keep for themselves. @EclipseVentures led the seed when nobody else would. now they're profitable, and he says they didn't even need to raise.

i also asked him if AI is a bubble, why america hates data centers, and why every oxide employee makes the same salary.

The best teams in the world just put their heads down and execute

The fastest inference in the world is coming to @OracleCloud.

@cerebras and @Oracle partner to enable blisteringly fast inference on OCI.

Cerebras brings fast AI.
Oracle brings deep expertise building and running AI infrastructure at scale.

Enterprises have trusted Oracle with their most important data and applications for decades.

Partnering with Cerebras gives Oracle customers more choice to match each AI workload to the compute that suits it best.

Coming soon, they’ll be able to build agents with true super fast AI in the cloud they already use.

Thank you to @MThiagarajan_ and the @Oracle team.
Excited to build this with you.
