Satellite manufacturer Apex Space has secured $200 million in new funding at a valuation of $2.3 billion, as the company accelerates plans to expand production capacity and strengthen its position in the growing space infrastructure market.
The funding round was led by Glade Brook Capital Partners, with participation from Washington Harbour Partners and a mix of new and existing investors. According to Apex CEO Ian Cinnamon, the company is raising capital opportunistically in response to strong investor demand rather than categorizing the financing under a traditional funding series.
Third Major Funding Round in 14 Months
The latest investment marks Apex’s third $200 million capital raise in just over a year. The company previously announced a $200 million Series C round in April 2025, followed by a $200 million Series D financing in September 2025.
The fresh capital will be used to expand Apex’s California manufacturing facility by an additional 30,000 square feet, increase in-house production of satellite subsystems, and support the company’s strategy of building satellite buses before customer orders are received.
Apex aims to offer ready-to-deploy spacecraft platforms that customers can purchase off the shelf, reducing development timelines and accelerating mission deployment.
“Over time, we’ll get to 100% vertical integration as we scale up and need to source higher volume of parts,” Apex CEO Ian Cinnamon told.
Expanding Manufacturing and Leadership
As part of its growth plans, Apex has appointed Michael Kopet as chief financial officer. Kopet previously served as Vice President of Finance at Axon, a technology company focused on public safety solutions.
The company said the additional manufacturing capacity and expanded in-house production capabilities will help streamline operations and improve supply chain resilience as demand for satellite platforms continues to grow.
Preparing for Project Shadow Launch
Apex is also advancing its Project Shadow mission, a commercial space-based interceptor demonstration scheduled for launch this summer.
The mission will be the first to fly aboard Apex’s Nova platform, the company’s mid-sized satellite bus designed for national security and commercial applications.
Earlier this week, Apex announced a partnership with Northrop Grumman to explore the development of space-based interceptor satellites for the proposed Golden Dome missile defense architecture. The collaboration is separate from Project Shadow, which Apex continues to pursue independently.
Growing Demand for Satellite Infrastructure
Founded to provide standardized satellite platforms, Apex has emerged as one of the fastest-growing companies in the commercial space sector. The company’s strategy centers on reducing spacecraft procurement timelines by manufacturing satellite buses in advance, allowing customers to focus on payload integration and mission-specific requirements.
The latest funding underscores continued investor confidence in satellite manufacturing as governments and commercial operators increase spending on communications, Earth observation, defense, and space security infrastructure.
With additional capital, expanded production facilities, and upcoming demonstration missions, Apex is positioning itself to scale manufacturing while supporting both commercial and national security space programs.
