Flow is accelerating the future of hardware development

We're building the "Github for hardware," enabling the new generation of hardware companies in space, defense, transportation, new energy and aviation to bring their products 100x faster. Today, 80% of the world's orbital payload mass into space is launched by companies using Flow.

When we return to the Moon, or make it to Mars—Flow will have been a small, but critical part of these journeys.

Powering the planet's fastest-moving hardware teams

We with with the most interesting hardware companies building complex systems for space, defense, satellites, robotics, and new energy nuclear and fusion technologies.

Backed by top operators and hardware investors

Flow is supported by visionaries driving the new golden age of hardware and by industry leaders who have set the standard for collaboration tools in other fields.

Working at Flow

Join the fastest-growing software-for-hardware startup

Flow operate extremely differently to most companies in the world.

Our mission is to change how engineering and hardware design is done on a global scale. Success means making a direct impact on the course of humanity.

We’ve already built a product that NASA and SpaceX tried to create—but couldn’t. Along the way, we’ve earned the trust of the world’s leading hardware companies.  Achieving something this ambitious can’t be done the “traditional way.” It demands a different way of working.

The best things in the world are evolved, not invented. Our role is not to come up with good ideas in a vacuum, but to learn what the right solution is by making small, tactical progress daily.

We ask more of our people, but the rewards are immense: real-world impact, meaningful outcomes for our customers, and unmatched personal growth. When we succeed, we’ll have built not just an industry-defining product but also a lean company with an outsized influence.

Culture

Operating Principles

Move Fast, Learn Faster.

Today, not tomorrow. Speed matters more than perfection. Quantity leads to quality. Mistakes are fine; inaction is not. Urgency is case. All progress comes from repetition and evolution. Playbooks are overrated; earned knowledge is 100x more valuable.

Minimize scope, Maximize Quality.

Downscope and ship. Quality is all that matters long-term, scope is flexible. Manual and functional beats over-engineered and complex. We ship fast. Product over process.

Customer Are the Heroes.

We exist to serve our customers and their mission. Our commitment is total and unwavering. Every interaction matters. We’re always delighted to be proven wrong because it means progress. Care, humility, and excitement drive our impact.

Relentless Optimism.

All in. Whatever it takes, we make it work. Solve problems in real-time, learn on the fly, and adapt as we go. We don’t hope for success, we make it happen. Extreme humility. Complete ownership and agency.
