🧵1/ Garage Land: How Ukraine’s wartime defense tech startup scene is changing the future of warfare.

The war triggered a mobilization in garages and workshops across Ukraine, spawning cutting-edge innovations and hundreds of defense tech startups. Image
2/ For Americans Justin Zeefe and Deborah Fairlamb, the war was a wake-up call.

They met in early 2022 and launched Green Flag Ventures (GFV), a VC fund backing Ukraine’s wartime tech startups—and taking them global. Image
3/ Ukraine can sustain itself through innovation, Zeefe said. These companies develop and battle-test technologies faster than anyone.

GFV funds early-stage firms needing $100K–$600K.

Ex:
— Kara Dag (drone countermeasures)
— Himera (tactical comms)
— Swarmer (drone swarms) Image
4/ Zeefe, a former US intel officer, and Fairlamb, embedded in Ukraine’s tech scene since 2004.

“Our skills just clicked,” said Zeefe. "Deborah brought deep financial and local knowledge, I brought ops and intel. Together, we could help these founders survive and grow.” Image
5/ The two see echoes of 1990s Israel: a culture of ingenuity, a surplus of engineering talent, and innovations tested under extreme conditions. “Wartime creates clarity. These startups move fast and build things that work,” Zeefe said. Image
6/ Ukraine’s defense sector is booming: $1B output in 2022 is expected to reach $15B this year.

Hundreds of startups are now working alongside state firms to build drones, artillery, and smart weapons. Image
7/ But while Ukraine innovates, allies lag behind.

Ukrainian firms iterate weekly. U.S. defense startups spend billions—and struggle to get prototypes off the ground.

WSJ reported many U.S.-built drones can’t even fly reliably. Image
8/ Drones in Ukraine are also upgraded every few weeks, far faster than the Pentagon’s years-long budgeting cycle. Californian startup CX2 says no US company is matching Ukraine’s pace. Image
9/ In 2023, Ukraine launched Brave1, a national platform to fast-track defense tech.

Now supporting 1,500+ startups with grants and technical aid, Brave1 helped push defense tech investment from $5M to $40M in one year. Image
10/ Ukraine’s decentralized model creates intense competition. Dozens of drone models are fielded and improved constantly.

Russian state media admitted that their forces near Pokrovsk are facing “massive attacks by Ukrainian drones.” Image
11/ With European support, Ukraine now produces 40% of its military needs domestically.

The UK, Denmark, Sweden, and the Netherlands are pouring funds into Ukrainian drone tech—knowing they’ll benefit too. Image
12/ Lyuba Shipovich, CEO of Dignitas, which runs the @VictoryDrones project, said her team collaborates directly with Ukrainian soldiers on the frontline. This allows them to receive instant feedback, quickly improve technologies, and redeploy them to the battlefield. Image
@VictoryDrones 13/ Yet, despite the battlefield success, Ukraine’s defense innovators still face major funding gaps. Of the $3bn invested globally in defense tech in 2024, only $100m went to Ukrainian companies, Zeefe said. Image
@VictoryDrones 14/ But interest is growing. In just six weeks, GFV raised $2m, bringing its total to $5.2m of a $20m target. Europeans, particularly in Scandinavia, are showing strong interest, and other NATO countries want to place direct orders with Ukrainian companies. Image
@VictoryDrones 15/ The GFV fund expects to deploy all capital by the end of 2026 and launch a larger second fund in early 2026. Zeefe is also betting that the world’s reliance “on Ukrainian experience and leadership in defensive readiness capabilities” will grow. Image
@VictoryDrones 16/ Ukraine’s resilience is showing that wartime innovation can attract investment and bring real results. As Europe scrambles to rearm for a potential future conflict with Russia, Ukraine’s tech will become an important part of the continent’s security architecture. Image
@VictoryDrones 🧵End of the thread.

1/ Panic spread across Russian military channels in early February after Starlink imposed new restrictions on satellite communications.

Unregistered terminals in Ukraine were disconnected following mandatory verification announced by Defense Minister Mykhailo Fedorov.

🧵 Image
2/ Russian soldiers quickly took to social media to complain.

One was filmed kicking his Starlink terminal. Another used it as a dining table.

“In a single night we completely descended into the Stone Age,” one soldier said.
3/ Within days, Ukrainian electronic warfare expert Serhii Beskrestnov reported Russian assaults stalling across multiple sectors.

“The enemy has a catastrophe,” he said.

Cloudflare data showed a clear drop in Starlink activity.

1/ The scramble for battlefield drone experience has become a global phenomenon.

Ukraine is now the world’s classroom for modern war.

🧵 Image
2/ While embedded with Colombian soldiers on Ukraine’s front lines, several told me they had fought cartels and insurgents before.

They had not seen warfare under drone dominated skies before.

That experience is now very valuable around the world. cepa.org/article/libert…
3/ Ukraine is where the learning is happening.

Ukrainian drones have struck targets more than 1,200 miles away, including a Russian shadow fleet oil tanker and even a submarine parked in a Russian port.

Kyiv regularly bombs targets across Russia.

1/ Cheap unmanned systems have reshaped modern warfare.

Ukraine has built a drone wall on land, forced Russia’s Black Sea Fleet into retreat at sea, and struck deep inside Russia.

Now those battlefield lessons matter far beyond Ukraine — including in the Arctic.

🧵 Image
2/ As Moscow accelerates its race for Arctic resources and intensifies pressure on NATO airspace, the High North is becoming a frontline.

As Mike Pompeo warned in 2019, the Arctic is now an arena of global power competition — and Washington wants to regain dominance.
3/ Russia’s Arctic strategy is driven by insecurity: fear of losing military dominance as ice melts and NATO expands, and fear of economic isolation as sanctions choke access to Western tech.

Finland and Sweden joining NATO only sharpened those anxieties. Image

1/ Ukraine says it has disabled a Russian submarine using an underwater drone—marking what Kyiv describes as the first successful combat strike of its kind.

It took a multi-step phase to execute.

🧵

2/ According to Ukraine’s Security Service (SBU), the attack damaged a Russian Kilo-class submarine in the Black Sea port of Novorossiysk, a key launch platform for Kalibr cruise missiles.
3/ The strike reportedly used an underwater drone system known as Sub Sea Baby. Ukrainian officials claimed the submarine was effectively put out of action.

Russia denies that the submarine suffered extensive damage. Image

1/ Ukrainian Naval drones hit two Russian shadow oil tankers off Turkey's coast on Nov 28, expanding Ukraine's kinetic sanctions program.

The strikes targeted vessels carrying around $70 million worth of oil off the coast of Turkey.

🧵 Image
2/ The targets: Kairos & Virat -- both flying Gambian flags but identified by Western authorities as part of Russia's "shadow fleet" designed to evade sanctions.
3/ The strikes occurred 28-35 nautical miles off Turkey's Kocaeli province, well beyond Ukraine's previous operational range in the northern Black Sea.

This represents the technological progress Kyiv continues to make, and also, increased boldness.

1/ Ukraine’s drone revolution is forcing Europe to confront an uncomfortable truth: you can’t defend a continent with million-dollar missiles against $20k drones.

What Ukraine learned through survival, Europe is learning through necessity.

🧵 Image
2/ Across Europe, cheap drones have shut down airports and crossed borders.

Officials say Russia is likely behind some of these flights, testing how NATO reacts.

Hybrid warfare grows: telegraph.co.uk/world-news/202…
3/ The cost gap is huge:

• A Patriot interceptor can cost several million for example.

• A Shahed-style drone can cost $30k–$60k

Not many other options are scalable, even deploying helicopters across the front.

Europe can’t win trading expensive shots for cheap targets.
