Congrats to @FocusedEnergy_1 on a landmark $240M round — the largest fully secured Series A in the history of global fusion energy. This is a major step toward making laser fusion an industrial reality. Proud to have been a partner on this journey. 🔬📷

Figure just turned 4 years old

The ride so far has been surreal, and I wanted to share my perspective on what’s happened over the last four years

When I started Figure, the core technologies were still extremely nascent. Humanoid hardware was heavy, hydraulic, unsafe, expensive, and unreliable. Deep learning also wasn’t there yet - there was no real AI precedent and no clear path to building a truly general-purpose robot

My expectation was always that humanoid robotics would become the largest industry in the world, but that it would take a very long time to put all the hardware and AI pieces together

Honestly, I assumed it would take 20 years just to have a real shot at solving general robotics - decades before we could seriously attempt to build iRobot in real life

Instead, everything has moved much faster than I ever expected. Figure has gone through 4 major breakthroughs that probably accelerated our timeline by a decade:

> Cheap electric humanoid robots are now possible. There are many reasons for this but some include benefits from actuator torque density, sensor technologies, battery specific energy, high flop/memory onboard compute, and high-rate manufacturing techniques all helped significantly. At this point, we’ve largely de-risked the hardware side and it’s becoming a straightforward engineering problem (highly difficult engineering but tractable)

> Deep learning from camera pixels to torques actually works. The dimensionality of a humanoid robot is simply too high for hand-written code. You have 40+ motors that can rotate continuously, creating more possible robot body states than atoms in the universe. There is no path to building a truly general-purpose robot with heuristics and manually programmed C++ logic. This has to be AI-first, and Helix has now demonstrated that repeatedly

> Whole-body RL control changed everything. It’s what keeps the robot balanced, allows it to use stairs, move its arms, and coordinate its entire body through the world. We train these controllers entirely in GPU-accelerated physics simulation using reinforcement learning. The robustness is far beyond anything we ever achieved with hand-written heuristics. This fundamentally breaks the old thesis that walking robots are inherently too hard or too unstable to scale

> These robots can now perform useful human-like work at human-level speeds. This is an insanely hard problem because humans perform millions of different tasks in the real world - and Figure has to do this with 1 hardware platform in a general purpose architecture. btw, yesterday Figure completed a logistics use case running continuously for 200 hours without a failure - all with scalable hardware and internal AI models

The future is starting to feel very real

We have a real chance to build iRobot in real life - the good version

Thank you for everyone's support. Pedal to the metal

Proud to lead the $14.3M seed round in @ThePathAI — an AI therapy and coaching app co-founded by @TonyRobbins. 1 in 5 people experience a mental health condition. AI can close that gap. Read more in @TechCrunch. https://t.co/pXedhb8Kg9

Prime Movers Lab just invested in the @hark_labs $700M Series A. @adcock_brett built Archer. Then @Figure_robot ($39B valuation). Then self-funded Hark before taking a single institutional dollar. When Brett starts something new, we show up. We're in.🔗 See why we invested: https://t.co/umQjQ6dL1C

[Prime Movers Lab @PrimeMoversLab]

Congrats to @adcock_brett and the entire @Hark team on an incredible milestone. $700M raised at a $6B valuation — and we're proud to be investors alongside an exceptional syndicate. The vision of a truly personal intelligence that thinks with you is exactly the kind of breakthrough science we back at Prime Movers Lab. The future is being built.

[Tony Robbins @TonyRobbins]

Huge congratulations to @adcock_brett and the entire @hark_labs team on raising $700M at a $6B valuation.

What Brett and the team are building is truly incredible — a company that's thinking deeply about what people actually need from technology, not just what's possible to build.

So proud of our partners at @PrimeMoversLab for being part of this round. Big things ahead! 🙌🔥😎

[Brett Adcock @adcock_brett]

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

Visited @Figure_robot's campus last month, an AI Robotics company building the world's first commercially viable autonomous humanoid robot.

Congrats to @adcock_brett and the team — and proud to be part of this journey alongside @DakinSloss and @PrimeMoversLab.
