Founders call it Ukraine. History calls it the Borderlands — the place between the West and the other, where freedom has been defended for as long as freedom has existed. The frontiers of freedom. Serhii Plokhy calls it the Gates of Europe, and he means it literally: civilization has lived on this ground for seven thousand years, longer than the pyramids have stood.1 The Borderlands have been the borderland of civilizations — not just empires — and what is decided here has always reached far beyond here.
There is a law that governs everything built for war, and it has never been repealed:
In war, every product and every person gets found out.
Not in the demo. Not in the pitch. In contact — against an enemy who adapts, jams, deceives, and shoots back. The question for every founder and every investor in defense is not whether you will be found out. It is when, where, and at what cost.
A sword that has never touched the stone is not a sword. It is a sword-shaped object. And most of what the West calls its arsenal today — and most of what its brightest new companies are building — is exactly that: unsharpened, untested, and marketed as ready.
The whetstone
There is one place on earth where the stone exists.
Ukraine is fighting the largest, most technologically advanced war since 1945 — against the exact adversary, and the exact axis, the free world will face everywhere else. The entire discipline of modern war — how drones hunt, how jamming kills, how humans and machines actually fight together — is being written there, nightly, by the people living it.
You cannot learn this from a briefing. I say that as a man who has spent twenty years on both sides of the briefing table. The distance between what Washington believes and what a soldier at the front knows is the most dangerous gap in the free world — and no report crosses it. Only presence does. In Ukraine the rule is absolute, and I have watched it open doors all the way to the Land Forces Commander: if you don't come, you don't exist.
I learned that lesson long before this war. In Iraq, the thing that saved my troop from a truck bomb was not technology. It was the local police we fought beside and lived among — embeddedness, presence, trust. War is a human endeavor, and humans do not extend trust across an ocean.3
That is what "sharpening the sword" means. It is not testing a product. It is testing a company — its engineers, its assumptions, its honesty — against the only judge that cannot be lobbied. Ukraine is a crucible, not a market. I have watched it take a navigation system two years deep in expensive hardware and remake it, in two weeks of unit testing, into pure software that works on any camera, day or night — and I have watched it take a founder whose demo died on the bench at dawn and hand him back, fourteen days later, a combat unit preparing a letter of interest for $10 million a year.2
The ones who go during
In 2022, when Kyiv held, my wife and I faced the decision of our lives: stay in the safety of America, or go home to the war. I told her something I believe more with every passing year:
The people who lead a country after a war are the ones who were there during it. Everyone else is a carpetbagger.
One refusal follows from this, and I say it without apology: I don't want to be a war tourist, and I don't help people who are.
The same is true for companies. When this war ends — and it will not end the way most people think — there will be two kinds of defense companies: the ones whose products and people were sharpened here, trusted here, remembered here — and the ones who watched. The contracts, the alliances, and the history will belong to the first kind.
The objections — and the rules
Every founder who decides to go hears the same five sentences before they leave: there's no money in Ukraine · it's corrupt · it's not the war we'll fight · nobody requires it · your investors won't allow it.
I've spent three years watching those five sentences stop brilliant people at the border. Every one of them is either half-true or exactly backwards — and in the talk, I take them apart one by one, with receipts.
And for the ones who come: there are ten rules of conduct that decide who becomes real here and who goes home. Like Fight Club — except the first rule of Ukraine, you say out loud, and I'll give it to you now: Be for Ukraine. The country can tell in one meeting who came to give and who came to take.
The other nine, I teach with the stories of the companies that lived them — including the failures. That, plus the map of what comes after this war, is the rest of the talk.
One part of this manifesto remains. It's not about war, the world order, or Ukraine.
It's about whether you're the kind of person any of this was written for.
Footnotes & further reading
- The Cucuteni–Trypillia settlements south of Kyiv (~5500–2750 BC) were among the largest in Europe. I learned how deep this land's memory runs from the historians — and once, memorably, from Norman Ohler, who came to Kyiv researching his next book and detoured to the Trypillian sites. On the sweep of Ukraine's history: Serhii Plokhy, The Gates of Europe. ↩︎
- Both companies are real. The exoskeleton founder is David Venegas of EdgeRun — the same founder whose living room this talk was first given in, to his peers. The rest of both stories is told on my list. ↩︎
- What presence costs, and what it buys, at two in the morning in a town near the front — that story goes only to the list. The asymmetry is the point: our clients take a 6 because we take the 11. ↩︎
