Apex Raises $200M

Glade Brook Capital Partners and Washington Harbour Partners led Apex’s $200 million funding round.
The round was oversubscribed in roughly 10 days, raising Apex’s total capital above $718 million.
Apex deliberately declined the full amount offered to “hunker down” and focus on building the business.
The two firms also backed launch startup Stoke Space’s Series D round last year.
The space-industry financing surge includes a $500 million round announced for Impulse Space.

History

Historical Context

In August 2006 NASA launched the Commercial Orbital Transportation Services (COTS) program, selecting SpaceX and Rocketplane Kistler for ISS flights and offering up to $207 million for milestones. After Rocketplane missed financing and NASA ended the contract in 2007, COTS proved funding can create launch capability. Apex’s $200 million round, led by Glade Brook Capital Partners and Washington Harbour Partners, follows model expanding thruster and satellite-bus production.
