Los Angeles-based space tech startup Apex has raised $200 million in a Series C funding round, less than a year after closing a $95 million Series B. The latest round was led by 8VC and Point72 Ventures, with participation from Andreessen Horowitz, Washington Harbour Partners, and StepStone Group.

Apex specializes in producing satellite buses — the central structure of a spacecraft — at scale. Its goal is to meet growing demand from both government and commercial clients, including the U.S. Department of Defense.

Scaling Up for National Security and Commercial Growth

“Apex’s way of building spacecraft is essential to achieving U.S. goals in both national defense and the commercial space industry,” said CEO Ian Cinnamon. “This funding allows us to grow production in advance of demand, supporting missions for key customers such as defense contractors, government agencies, and leading private companies.”

The company plans to expand its manufacturing capabilities and increase inventory to shorten delivery times for satellite components — a critical need in today’s rapidly evolving space tech sector.

Investor Interest Grows in Space Tech

Investor interest in defense-related technology has been climbing. While broader space tech funding remains cautious — with $1.7 billion invested in venture-backed space startups in Q1 2025 — some companies are securing major rounds.

Other recent high-profile investments include:

• Stoke Space, a reusable rocket startup, raised $260 million in its Series C.
• Epirus, focused on directed energy defense systems, raised $250 million in a Series D.

Though total space tech investment last year reached $12.5 billion, 2025 is already seeing significant activity among companies positioned at the intersection of defense and space innovation.
