Culver City space manufacturer Apex is raising $500 million in a funding round that would value the company at around $4 billion, roughly double its April 2026 valuation. Washington Harbour is expected to lead the round, with Andreessen Horowitz and XYZ Venture Capital also participating, which matters for California startups watching how late-stage capital is flowing into aerospace.
Why it matters
The round would be Apex's sixth funding round in four years, signaling how aggressively investors are backing manufacturing-focused space companies. Capital concentration at this scale can tighten access for smaller California aerospace suppliers competing for the same investor attention and talent.
Apex's proposed $4 billion valuation would double its $2.3 billion April valuation, and the round would follow $400 million raised in back-to-back 2025 rounds and a $200 million round in April. California's aerospace and defense sector has raised around $21 billion so far this year.
The players
Apex
Culver City space manufacturer that builds satellites using a factory-based production model, with growing capital backing from venture investors.
Washington Harbour
Investment firm expected to lead Apex's proposed $500 million fundraising round.
Andreessen Horowitz
Menlo Park venture capital firm participating in Apex's proposed round, with a broad portfolio of technology and infrastructure startups.
XYZ Venture Capital
San Francisco venture capital firm participating in Apex's proposed round.
Elveo Mobile
Washington, D.C.-based company developing a direct-to-device satellite constellation that Apex will help manufacture under a September partnership.
The details
Apex leverages a factory-based manufacturing model, which it used to form a partnership with Elveo Mobile in September. Under that arrangement, Elveo and Apex will establish a factory dedicated to scale manufacturing Elveo's direct-to-device satellite constellation. The model ties Apex's growth to dedicated production capacity for a specific customer rather than one-off build contracts, which is why investors are pricing the company on manufacturing scale.
Timeline
2022: Apex was founded in Culver City.
2025: Apex raised $400 million across back-to-back rounds, including its series C.
April 2026: Apex closed a $200 million round at a $2.3 billion valuation.
September 2026: Apex and Elveo Mobile announced their factory partnership.
Late October 2026: California's aerospace sector had raised $21 billion for the year.
Market Landscape
Apex's proposed round extends a pattern of rapid repeat fundraising among California space startups, alongside Impulse Space and K2 Space, which were also founded in 2022 and have each raised five rounds. The sector's roughly $21 billion in funding this year places Apex's round within a broader, capital-intensive buildout of satellite manufacturing.
Operators of California aerospace suppliers should expect heavier competition for skilled manufacturing labor and capital as well-funded players scale. Companies that sell into satellite manufacturing should monitor whether large rounds translate into longer-term procurement commitments.
The takeaway
The key operating signal is that capital is rewarding manufacturing capacity tied to a named customer, not just technology. Track whether Apex's round closes at the proposed terms and whether the Elveo factory partnership moves toward production.
