ZeroMark

Imagine you never miss. ZeroMark turns a firearm into a handheld “Iron Dome” — against drones & other dangers. For military and law enforcement only.

[ZeroMark @zeromarkinc]

C-UAS in soldiers’ hands.

AI-powered accuracy.

It’s coming.

[joelcpanderson @joelcpanderson]

@ycombinator @bosmeny We couldn’t agree more. That’s why we built it…. Want to demo it in the field @bosmeny?

I sat there in the front row, the hum of the room buzzing like the rotors of a drone swarm I've spent sleepless nights engineering against. March 3, 2026, @a16z American Dynamism Summit. @KTmBoyle on stage, sharp as a targeting laser, firing questions at Alex that cut straight to the bone of what we're building in defense tech. No theatrics, no mockery of war from VCs in tailored suits. Just raw patriotism wrapped in realism, the kind that saves lives on battlefields where hesitation means death.

I'm the founder of @zeromarkinc, an a16z portco where we don't spin yarns or chase hype. We forge iron. AI fused with hardware and software, turning rifles into real life aimbots. Our systems let warfighters drop UAVs like flies and ensure they never lose a gunfight.

Feet away from Karp, I heard every word unfiltered: advice for founders like me, navigating the storm of AI's rise. He laid it out plainly... refuse to play in defense, and nationalization isn't a threat, it's the horizon. No standing ovation erupted; the room absorbed it, heads nodding in quiet resolve, not applause. It echoed what @PeteHegseth has hammered home: "We will harness more of America's innovative companies to focus their talent and their technologies on our toughest national security problems."

Then I scroll X later, and there's this post from @gothburz, weaving a satire so vivid it almost fools the feed. Powerful prose, uniquely carved, but a fabrication born from speculation, not sweat. He wasn't there. I was, close enough to see the lines on Karp's face, feel the weight of his warnings. What a waste of words when the real story is builders, grinding in labs and fields, turning tech into shields for those who stand the watch.

I wish more would show up to these summits, trade tweets for truth, keyboards for action. We don't talk at ZeroMark. We do. And in doing, we arm the future against the fools who fire from afar, embodying @davidu's take that "our national security depends on all of them advancing as quickly as possible.”

9 drones, 9 kills, 30 seconds.

Brought to you by ZeroMark Vanguard, our newest addition in the auto-target product line for our warfighters.

We will win. 🇺🇸

[ZeroMark @zeromarkinc]

Thank you @SecArmy & @SenatorSlotkin for showing the surefire way to down drones @CampGrayling

[joelcpanderson @joelcpanderson]

One shot, one kill.

@SecArmy paired with ZeroMark is a lethal combo.

Today is Memorial Day—a day reserved for honoring those who made the ultimate sacrifice in service to our country. It is not just a day off work or the unofficial start of summer; it’s a solemn reminder of the enormous price paid for the freedoms we enjoy.

Since America's founding, more than 1.3 million service members have laid down their lives in war. Each of those lives was a universe of potential… fathers and mothers, sons and daughters, brothers and sisters... lost forever.

The scale of their sacrifice is humbling:

In the American Revolution, over 25,000 lost their lives, fighting to establish a nation rooted in liberty.

The Civil War claimed roughly 620,000 Americans, more than any conflict in our history, as the nation struggled to define its very soul.

World War I took over 116,000 lives, young soldiers crossing oceans to face battles far from home.

World War II saw more than 405,000 Americans perish, sacrificing everything to confront unimaginable evils.

Over 36,000 fell during the Korean War and more than 58,000 during Vietnam, each loss felt deeply by loved ones back home.

In recent decades, over 7,000 more have given their lives in Iraq, Afghanistan, and in battles fought in quieter corners of the world, often without public recognition, but always with unwavering courage.

Behind each of these numbers is a name, a face, dreams, and a family forever changed. Today, let us remember them not just collectively, but individually, acknowledging that their sacrifice was real, personal, and profound.

Take a moment today to truly reflect on this. At 3 PM local time, as part of the National Moment of Remembrance, pause for just a moment of silence, honor their memory, and quietly reaffirm that their sacrifices will never be forgotten.

Fun Day at SOF Week 🇺🇸🚀💪

"Shooting down a drone is like being in a firefight, that's not a place you want to be. But when you're there, you need your tools to work."

[joelcpanderson @joelcpanderson]

Not all drones are equal. Electronic countermeasures alone won't protect us—basic mods can defeat million-dollar systems. Kinetic defense isn't comfortable to discuss on U.S. soil, but it's critical. Broke this down on @CNN's NewsNight with @abbydphillip. #newjerseydrones #cuas

[ZeroMark @zeromarkinc]

If this feels like science fiction, take a look at "Slaughterbots" for a chilling glimpse of how drones could cause mass chaos. It’s fictional, but disturbingly plausible—and exactly why we must act now, before reality mirrors the worst imaginations.

🚨 Mystery Drones Over NJ: A Domestic Security Gap We Can’t Ignore 🚨

I’ve been on @CNN , @NewsNation , @CBSNews , & @BBCNews discussing the thousands of unidentified drones over NJ. Rumors are swirling—foreign adversaries, secret U.S. ops, even aliens. The truth? Their origin matters less than our defenselessness to any drone with malicious intent.

Drones are here, now—and without urgent action, we risk real harm.

Best part of MCBH is the secret beach and how unbelievably scenic the shooting range is. We had a blast with 3MLR, PACAF, and NSIN 🗽🇺🇸

[joelcpanderson @joelcpanderson]

I guess I'm throwing in the towel. It's way cheaper to throw your rifle at drones than buying @zeromarkinc

[ZeroMark @zeromarkinc]

@Jkylebass @PeteButtigieg We have the tools to deal with this. And we'd argue these activities are a threat to life and thus interdiction should be legal under title 18 and 49.

[ZeroMark @zeromarkinc]

@jordanodinsky @joelcpanderson @jtriest This.

[ZeroMark @zeromarkinc]

Crushing it on special operations rules.

Rule 1: Look cool
Rule 2: Know what you’re doing
Rule 3: If you don’t know what you’re doing, refer to Rule 1

Also, your long distance pistol performance was 🔥

[Greg Castle @gpcastle12]

Excited to back this stellar team and product🇺🇸

Good news for TechCrunch!

The Chinese Army is building technology to counter politically controversial American startups!

If it works, China could permanently rid the world of political controversy forever!

[Katherine Boyle @KTmBoyle]

It is not controversial to give our men and women in uniform technology that actually works.

It’s no longer 2017.

[David Ulevitch 🇺🇸 @davidu]

This technology saves lives. 🎖️

[Aria Alamalhodaei @breadfrom]

This week didn't have enough political controversy, so let me introduce you to a16z-backed ZeroMark, a startup that wants to give unmounted soldiers a 'gun that doesn't miss' drones:
