Apex's $16 million Series A funding round, which brings the company's total funding to over $27 million, was led by venture capital firms Andreessen Horowitz and Shield Capital. Apex will use the additional funding to open a new, 50,000 sq ft production facility in Los Angeles dedicated to serial bus manufacturing. This investment and the new factory will allow the company to expand its production rate and further reduce lead times for its customers.

Apex manufactures spacecraft for both commercial and government customers. Apex's first product, the Aries satellite bus, is a 103kg spacecraft platform capable of holding a customer payload as large as 94kg. Apex sells the Aries platform to companies operating in low earth orbit, flying payloads for a wide variety of missions, ranging from earth imaging to communications. The Aries platform is available off the shelf or can be configured to meet specific mission requirements.
