Space is becoming infrastructure.

For most of the last century, space was defined by exploration, national ambition and scientific achievement. That era continues — but another has begun.

The New Space economy is being built around what space makes possible: intelligence, connectivity, navigation, security, autonomy, climate resilience, logistics and entirely new forms of infrastructure.

The next generation of space companies will not only build rockets and satellites. They will combine space, AI, autonomy, advanced hardware, robotics, data and dual-use technologies to solve problems on Earth, in orbit and beyond. Build for Space exists to help build those companies.

Build for Space is a strategic venture-building platform for the New Space economy. We identify important capability needs and industry challenges, translate them into opportunities for builders, and connect exceptional founders with the customers, partners, expertise and capital needed to turn ambitious technologies into globally significant companies.

Our starting question is simple:

What needs to be built next?

Through our Calls to Build, we surface problems worth solving across the emerging space economy and invite founders, engineers, researchers and technologists to build against them.

Our flagship programme is an intensive eight weeks in London for founders building space, AI and dual-use infrastructure. It is designed around commercialisation rather than acceleration for its own sake.

Founders work on what actually determines whether difficult technologies become real companies: understanding the market, validating customers, developing pilots, navigating procurement, building strategic partnerships, preparing for investment and creating a credible path to scale.

The objective is not to finish with a better pitch.

It is to leave closer to deployment.

Some of the most important companies of the next decade will emerge from problems that are already visible but remain insufficiently solved. Calls to Build is how we turn those problems into opportunities.

We look across governments, industry, infrastructure and emerging markets to identify capability gaps and important technical challenges — then ask founders to rethink them from first principles.

Our areas of interest include Earth intelligence, sovereign and resilient space infrastructure, secure connectivity, navigation, satellites, launch and mobility, autonomous systems, robotics, AI-native space software and airspace security.

The boundaries are deliberately open: we are interested not only in companies that go to space, but in companies that become possible because of space.

Space is becoming cheaper, more commercial, more software-defined, more autonomous and more strategically important.

At the same time, AI is changing what can be extracted from orbital data. Autonomous systems are changing how machines operate in difficult environments. Geopolitics is increasing demand for resilient infrastructure. Commercial customers are finding new uses for space-based capabilities.

These forces are converging, and the result is not simply a larger space industry.

It is a new economic layer.

New economic layers create room for entirely new categories of companies.

Great companies are not created by technology alone. They emerge when important problems, exceptional people, real customers and ambitious capital come together at the right moment. That is the role Build for Space plays.

1. Start with what needs to be built.
2. Find the people capable of building it.
3. Connect them with those who need it.
4. Bring in the capital capable of scaling it.

Turn capability into companies.

We are built for founders with deep technical or domain conviction, working on infrastructure that is hard to build and hard to copy, and willing to sell into demanding customers — governments, primes, operators and regulated industries.

We are not the right fit for teams looking for a badge, a demo day photograph or a first idea to workshop. The programme assumes you already know what you are building and want to shorten the distance to deployment.

Based in London. Selective by design, and global in who we look for.
