Building at scale, building at speed.

Proud to announce that our CEO and Co-Founder @lukasczinger will be taking the stage at @reindsummit 2026.

Reindustrialize gathers the most influential leaders across manufacturing, defense, venture capital, and industrial technology to discuss the systems, infrastructure, and technologies shaping the next era of American industry.

Today I'm excited to share that Hark has raised $700M at a $6B valuation

When I use these AI models today, they feel basic. They should be able to listen and talk naturally, understand vision, retain persistent memory, and become deeply personalized over time. They should be able to see the world, interact with it, and take action

To build that future, the capital we raised today will be used to:
→ scale our GPU infrastructure
→ accelerate future AI model development
→ grow the Hark team from ~70 to 200 engineers
→ design and build the next generation of AI hardware

The Series A round was led by Parkway Venture Capital with participation from NVIDIA, Align Ventures, AMD Ventures, ARK Invest, Brookfield, Greycroft, Intel Capital, Prime Movers Lab, Qualcomm Ventures, Salesforce Ventures, and Tamarack Global

At Hark, we are building the most advanced personal intelligence in the world. Intelligence that begins to think like you and sometimes, ahead of you to offload your mental workload

@geckorobotics has quietly become strategically indispensable before most people realize what happened, by building the real-time operating system for critical infrastructure. The combination of physical inspection + AI-generated asset intelligence is the beginning of a new industrial stack for defense, energy and manufacturing. Real time intelligence built on pipes, ships and power plants…

Featured: Reindustrializing America and winning the AI race vs. China, @IgnatiusPost visits Gecko for the @washingtonpost.

David Ignatius went behind the scenes and toured our robotics facility in Pittsburgh with @jakeloosy to see the groundbreaking technology delivering ROI for both government and commercial customers.

This is what scale looks like, congrats @JakeJurewicz and team ⚡️https://t.co/YCMD2BVZg1

So much obsession with existing TAM out there, exhibit A… that rare breed of founder that creates an entirely new market, 🙌🏽 @ADoricko

Mankind has always been at the mercy of the weather.

No longer.

Rainmaker is the first company in history to routinely, unambiguously, modify the weather.

Last quarter, we produced >143MM gallons of unambiguously man-made precipitation.

Here’s how we do it 🧵

[Ruairí McLoughlin @RoMcLocko]

Built this in 7 days in El Segundo
All-in cost: <$1,000

Working photobioreactor
• sensors, controls, light delivery

This is how fast iteration in biomanufacturing can move

Now imagine 1 month
Now imagine 1 year

Autonomous, robot-driven bioreactors coming next

We’re Raising

Hell yes

[rob eloff @robeloff]

Little known fact about El Segundo founders - they can walk on water. Last week’s cohort of @DiscipulusVent builders put their physics and judgement skills on display for a pre-demo day liquidity event with fearless leader @jakobdiepen and @KingJamieLee @tamarackglobal. Your move @PalmerLuckey

[rob eloff @robeloff]

Don’t sleep on @JakeJurewicz. For the U.S. to deliver scaled fission, balance of plant is the bottle neck. The team at Blue Energy execute at the speed and cost required for energy abundance. @tamarackglobal is honored to have the opportunity to continue backing this team https://t.co/OxpJNHbAGi

[rob eloff @robeloff]

Hardtech hits harder in El Segundo. @DiscipulusVent @jakobdiepen keeping it real with Cohort 4, well played.

[Tom Mueller @lrocket]

This is exactly the type of leadership we need right now to get us back on track. To the moon.!

@brexton @austinbishop Capital fluency is our business @tamarackglobal if you need directions on who wins at leasing, lending, warehouse financing and growth funding besides the obvious names us up.
