Flow has raised a $50M Series B at a $750M valuation, co-led by Antonio Gracias (Valor) and Gavin Baker (Atreides) with Sequoia Capital, Roelof Botha (SpaceX, Block), and more.
When I became a mechanical engineer, I wanted to invent. In reality, 90% of the day to day execution work (CAD, excel, sim) was digital manual labour. That’s about to flip. The engineer’s role will change more profoundly than at any point since the invention of CAD, with humans focusing on invention, architecture, tradeoffs and judgement calls, and agents taking the grunt work.
Anduril, Joby, Stoke Space, Rivian & many more - Flow is now the default platform for requirements and verification for frontier hardware teams. But it’s not just next-gen anymore. Industry giants including General Motors PPU and Volkswagen & Rivian’s joint venture (RV Tech) are reshaping their core development practices with Flow’s AI.
The revolution is just starting. Models are getting better quickly at CAD, analysis, simulation, and tool use. In the next year, AI will move from integrating the work to doing the work.
One day, this shift won't just enable us to iterate faster, it will enable us to design a class of products that we could not have dreamt of before.
We’re hiring.

Interfaces that are generated, not coded.
Solaris is our first step toward our vision of end-to-end neural software, where user interfaces are streamed directly onto your screen by a real-time video model, without any intermediate code or HTML/CSS. Today we're releasing a technical report and opening it up for limited testing by the community.
Amazing work by the team, combining the best of our research in general world models with Runway's HCI spirit.
Today, we're sharing new research on Solaris, our first Interface World Model.
Solaris is a new kind of operating system that generates interactive interfaces frame by frame, in real time, with no code. We find that Solaris outperforms frontier LLMs when generating new interfaces, across structural similarity and information retention. Read more and request early access at the link below.
I am so pumped for the Flow team and what they have built. I've been fortunate to see this team execute over the last couple years and build something truly amazing that is transforming some of the worlds leading physical engineering companies workflows. 🙌@parisingh
Agents have reached hardware.
We are launching Flow v3, the Agentic Platform for Physical Engineering.
We've spent over a year building it in secret, alongside the best hardware companies and AI research labs.
An agent can now do real engineering work: change a requirement, push the update into your CAD and simulation tools, and flag every test that needs to rerun. Iterations/learning cycles that took months are being reduced to days.
Agents are the biggest shift in how we engineer hardware since CAD.
The core innovation for the CAD era was the parametric model.
The core innovation for the Agentic Era is Flow's Systems Graph.
The systems graph is a living model of every requirement, design model, test, analysis and every connection between them. It gives every agent the full context of the system, so every change stays consistent across the whole design.
Engineers and agents work side by side on the same system. Engineers get to focus on architecture - the decisions that matter -while thousands of agents churn through rewriting reports, rerunning analysis and simulation, and triggering tests.
Reusable rockets, self-driving cars, small modular reactors, robots that make decisions, the most complex machines ever built, are defined by millions of interconnected requirements, far beyond what any human team can keep aligned on its own.
Rivian, Joby, Astranis, Skydio, Radiant, and the most ambitious hardware programs already build on Flow.

I'm back with a new pocket guide - 10 principles for better design critique.
I've sat in hundreds of design crits over 30+ years as a designer. These are tried and true.
Hemeon’s Pocket Guide to Design Critique
01 / Same Team, Same Goal
Critique is not a courtroom. It’s a shared effort to make the work better. The enemy is unclear thinking, weak craft, and lazy solutions. If it feels like combat, the culture is broken.
02 / Safety Is the Container
People don’t risk honesty when they feel exposed. They perform. They defend. They shrink. Strong critique only happens inside trust. Tend the room before you touch the work.
03 / Honesty Without Harm
Truth matters. So does delivery. Say the real thing, cleanly. You can be direct without being destructive. If people leave wounded instead of clearer, the moment failed.
04 / Critique the Artifact, Not the Human
The work is not the person. The draft is not the designer. Speak to flows, clarity, and decisions. The moment feedback touches identity, growth stops.
05 / Don’t Break the Good, While Fixing the Bad.
You can’t improve what you don’t yet understand. Naming strengths is not politeness. It’s precision. It tells the designer what to protect while they evolve.
06 / Taste Without Reason Is Noise
“I don’t like it” is not critique. It’s mood. Real feedback anchors to users, goals, systems, constraints, or craft. If you can’t explain why, it’s preference.
07 / Turn Reactions Into Direction
“Confusing” is a feeling, not feedback. Do the extra work. Translate reactions into requests. Direction moves the work forward. Vibes do not.
08 / Context Comes Before Solutions
If you don’t understand the intent, you’re solving the wrong problem. Ask first. What’s the goal? What’s fixed? What’s fragile? Critique without context is theater.
09 / All Notes Are not Equal.
A bug demands attention. A preference does not. When you label feedback clearly, the team can prioritize without emotional confusion.
10 / Many Voices, One Owner
Choose a clear owner.
Without ownership, critique becomes endless discussion.
Thank you for reading. Drop a comment on the best tips you have for running a design crit. Would love to hear your ideas!
Pretty impressed with how fast Cursor is shipping. This is a huge step forward for designers cursor.com/blog/browser-visu…

This is the craziest model you'll see this week!
This model powers Figma. It's also behind Wayfair and a bunch of major e-commerce retailers.
This model is a PIXEL-PERFECT image editing model.
Literally, "pixel perfect".
The model is capable of modifying one image while keeping everything else untouched.
It's a model designed, developed, and deployed by the research team at Jasper.
This beats OpenAI models, Nano Banana, and every single general image model I've seen so far. It's up to 100x less expensive to run, and up to 10X faster.
I recorded a quick video to show you how impressive this is.
There's a ton of research behind this model. I'm adding two links below so you can read about how this model works, specifically about "Latent Bridge Matching" and "Flash Diffusion".

Friendly reminder that one of the best things you can do for your own mental health today is to close this app, put down your phone, and go outside and express gratitude that you are here experiencing this life in all of it’s beauty and absurdity.
Just saw that Canva acquired Affinity. Such a powerful move on their part and clearly a move to reinforce their intention to unseat Adobe as THE creative platform for anyone. Thoughts on who wins the next era?

When you’re in the midst of building a product, you will often randomly stumble across an insight that completely invalidates your original thesis. In many cases, there will be no solution. And now you’re forced to pivot or start over completely.
If you’ve only worked at a big company, you will be instinctually compelled to keep going because of how pivoting would reflect on stakeholders. This behavior is essentially ingrained in your subconscious—from years of constantly worrying about how things could jeopardize your performance review, and effectively your compensation.
This is why so many dud products at BigCos will survive with anemic adoption.
Instead, it’s important to build an almost academic culture of intellectual honesty—so that being wrong is met with a quick (and stoic) acceptance by everyone.
There is nothing worse than a team that continues to chase a mirage.
Today seems to be full of awesomeness! Huge congrats to the team for shipping this. Consistently shipping groundbreaking new features and opening up even more creativity! 🙌
Multi Motion Brush represents a significant milestone in achieving genuine artistic and creative control. Expressive precision is crucial for a technology that is becoming a new medium.
MMB exemplifies the new principles and metaphors needed for the next generation of models. We are going from discrete to continuous. From 3D modeling, character rigging, texture creation, scene animation, effect simulation, rendering, etc., to only fluid world simulation. Eventually, all of it in real time.
A big shoutout to our research, engineering, and creative teams for advancing yet another step forward.
