Los Angeles satellite-bus manufacturer Apex announced on June 5 that it has raised over $200 million in new growth funding, nearly doubling its valuation to $2.3 billion just months after it crossed the $1 billion mark with its September 2025 Series D. Glade Brook Capital Partners led the round and Washington Harbour Partners co-led, with new and existing investors joining alongside.
Doubling down on proliferated constellations
The capital is earmarked for expanding Apex's Factory One campus in Los Angeles, deepening vertical integration of key subsystems and pre-building productized satellite buses ahead of customer demand. "Proliferation is the name of the game these days, and it's only possible with suppliers like Apex that can actually execute on their model to build satellites at an industrial scale," CEO Ian Cinnamon said in the statement. The company is adding 30,000 square feet of factory space and has more than doubled headcount in the past year to over 350 employees, with Factory One designed for peak output of more than 200 spacecraft per year.
Golden Dome and Project Shadow on the runway
Apex has already disclosed a collaboration with Northrop Grumman on space-based interceptor work for the U.S. Space Force in support of the Golden Dome for America initiative. Its own Nova 1 satellite, hosting Project Shadow — described as the first commercially led on-orbit space-based interceptor demonstration — remains on track for a summer 2026 launch and is intended to validate technologies behind orbital magazine architectures for missile defense. Glade Brook chief investment officer Paul Hudson framed the bet bluntly: "Space is undergoing a fundamental transition from bespoke programs to scalable, proliferated infrastructure."
A finance leader, a flight heritage, three product lines
Apex named former Axon vice president of finance Michael Kopet as chief financial officer alongside the raise, signaling a posture shift toward scaling commercial and government delivery. The company recently celebrated the two-year on-orbit anniversary of its first Aries spacecraft and now offers three platforms — Aries, Nova and Comet — with the recently announced Comet Mini configuration able to carry payloads up to 3,000 kg. Additional Apex satellites are slated to fly later this year, building flight heritage that customers like Apex's growing commercial and national security pipeline have made central to procurement decisions.
Apex's $2.3B mark lands the same week that SpaceX set its record $75B IPO price and the U.S. defense industrial base continues to expand into commercial space, including the Katalyst Link spacecraft cleared for the Pegasus XL Swift rescue mission. The raise also follows AeroVironment's $117M Army P550 contract, another sign that proliferated platforms are pulling growth equity into the defense supply chain.
