Flow raises $50M Series B at a $750M valuation, co-led by Antonio Gracias (Valor) and Gavin Baker (Atreides).

Help unlock the nextgeneration of hardware

Rockets, robots, reusable vehicles. None of it ships without systems engineering. We're rebuilding it for the agentic era.

Our Mission

Take the cost of designing complex hardware to zero. Put the engineering leverage of a thousand-person team in the hands of a team of ten. Unlock products no team can build today.

The new era we are building for

Once a generation, the way hardware gets built changes. We're at the start of the third one.

Analog. Digital. Agentic. Each shift compressed timelines by an order of magnitude and rewrote who got to build. The platform for this one does not exist yet. We're building it.

The companies that already use Flow are building the things that show up in the news. Reusable rockets at Impulse Space. eVTOL at Joby. Vehicles at Rivian and Volkswagen Group Technologies. Satellite constellations at Astranis. Robot fleets at Mytra.

Your work ships into theirs. The agent you build catches the conflict that would have grounded a prototype. The data model you design holds a program with hundreds of thousands of requirements together. The leverage is real, and the stakes are high.

What we believe in

Speed over everything.
A pothole at 20 mph rattles the car. At 200 mph you barely feel it. We move with urgency on purpose.
Ship a V1, then iterate.
We'd rather ship v1 today than show v4 in a deck next month. Execution is the only thing customers value.
Fundamentals, unbelievably well.
Most success is the basics done with care. Trade off scope, never quality.
Get on the plane.
Decide fast. Debate hard before the call, commit fully after.
Maximum effort, maximum fun.
The work is hard. The team is the reason it stays fun. Both are required.
The Flow Engineering team
Antonio Gracias, Founder and CEO of Valor Equity Partners
We spoke with some of the hardware companies we know best, and we heard extraordinary conviction about both Flow and the problem it solves. It is rare to see this level of demand for a product so early.
