Flow Engineering

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.

Anduril is an “all in” type of company.

Submarines are one of the most complex systems humans build. Anduril is committing $3.7 billion to help America build more of them.

I’m even more proud now that Anduril is a Flow customer.

The money is going into Arsenal-2, a new shipyard at Sparrows Point in Maryland. It’ll build components and large assemblies for Virginia-class submarines. The Navy has signed a contract worth up to $2.9B, paid out as Anduril actually produces.

Arsenal-2 isn’t expected to open until 2030, but Anduril isn’t waiting. They’re setting up a facility in Orange County, California, to work out their manufacturing methods and train the first team now. The process will have been tested long before the shipyard exists.

The machine that builds the machine is 100x harder, as Elon says. Getting the process right is most of the work. A part for a submarine has to meet its requirements, fit into a boat being assembled at Electric Boat or Newport News, pass inspection, and show up on time.

Anduril is the opposite to the cost plus model. They’re putting their own money to make this work, ahead of schedule. This is the new era for engineering.

The way people build software has changed completely in the past few years.

What about hardware?

For the people building important hardware (like rockets, cars, and robots), not much has actually changed. Software engineering has undergone this agentic AI revolution and hardware engineering is, for the most part, stuck with the same tools that have been around for decades.

The startup we wrote about this week, Flow Engineering (@flowenghq), is trying to bring the AI revolution to hardware.

They started with requirements (the thousands of rules a machine has to meet), connecting them to the designs, code, and tests, so AI agents can check every change against them. But the path ahead of them is a lot more ambitious.

Rivian and Anduril are customers, plus lots of others you’d recognize that Flow can’t name publicly. And just last month, Flow raised a $50M Series B at a $750M valuation.

Should you join?
