HEO, the Australian space surveillance company, has raised US$25 million — A$37 million — in a Series B led by Beaten Zone Venture Partners, to extend its satellite inspection business into geostationary orbit.

The business: renting other people's cameras

HEO photographs satellites and spacecraft using cameras aboard other satellites, catching them during flybys. Rather than launching a large constellation of its own inspectors, it has access to more than 50 sensors in orbit, eight of which it operates itself.

The capital efficiency of that model is the whole point. Space-based imaging normally means building and launching your own hardware. HEO's approach treats already-orbiting sensors as a distributed network whose spare capacity can be pointed at a target when the geometry lines up.

What customers get is something ground-based tracking cannot provide. A radar station can tell an operator where a satellite is and roughly how it is moving. A photograph taken from a few dozen kilometres away shows whether a solar array actually deployed, whether an antenna is bent, whether the spacecraft is tumbling.

"For commercial players, it allows you to really understand what's wrong with your spacecraft. So a bunch of companies have come to us when something's wrong," said co-founder and CEO William Crowe.

Who is buying

The customer list is the strongest thing in this round: Australia's Department of Defence, Japan's Ministry of Defense and the US National Reconnaissance Office. Those are the hardest procurement processes in the sector, and clearing all three establishes a credibility that is difficult to compete against.

The demand driver is uncomfortable but real. Geostationary orbit holds communications and early-warning satellites that governments consider critical infrastructure, and the number of manoeuvrable objects operating near them has grown. Knowing what is parked next to your satellite has become an operational question rather than an academic one.

"Some of the world's most critical infrastructure is operating tens of thousands of kilometres above Earth, but our ability to see and understand what is happening to it remains limited," Crowe said.

The investors

Beaten Zone Venture Partners led. Australia's National Reconstruction Fund Corporation put in $10 million, joined by Dcode Capital and existing investors Airtree and Salus Ventures.

The NRFC participation marks this as sovereign capability investment as much as venture capital — Australia funding a domestic space asset it would otherwise have to buy from allies.

The GEO expansion

HEO has operated in low-Earth orbit. The Series B funds the move to geostationary orbit through additional sensors, partnerships with satellite operators and software development. The first two launches are scheduled for later in 2026, with regular imaging coverage planned for 2027.

GEO is technically harder. It sits roughly 36,000 kilometres out, and flyby geometry is far less forgiving than in LEO, where orbital planes cross constantly.

The read

HEO spun out of UNSW Founders in 2017 and has reached three national defence customers without the capital those contracts usually require — a function of not owning most of its own hardware. That model is also the dependency: it relies on partner satellites, and partners can change terms. The GEO buildout, with 2027 as the coverage milestone, is where the company finds out whether its approach scales to the orbit its customers care about most.
