Spacetech, as with all innovation industries, sees the “summer dip” worst in August. 2025’s no exception – under $400m was invested this month, the lowest monthly total of the year.

33 spacetech companies received $346m in venture funding this month. The true total is likely much higher, as almost half of those deals had undisclosed totals (including potential megarounds by Chinese startups Aerospace Taixin Technology aka RocketHeart, Aurora starlink, and Beijing Interstellar Human Spaceflight Technology).

Contrary to their recent dominance at the top of the leaderboard, US startups slipped this month. Belgium’s Aerospacelab (€94m Series B), China’s Beijing Aerospace Yuxing Technology (CNY 430m Series C) and the UK’s Paragraf ($55m Series C) were the only startups to raise over $50m this month.

We are also seeing less (public) investment information shared about China’s startups in recent months, with the last two months missing the usual $100m+ megarounds that prop up a portion of the spacetech VC global industry total.

Estimating the size of the Spacetech industry:

SpaceWatch.Global estimates that so far in 2025, 162 companies have raised $4.6b. of venture equity funding.

Benchmarking our estimate:

The Dealroom/ESA Space Tech Dashboard is a great way to benchmark our estimate. Generally, the dashboard has a more expansive definition of spacetech (including, for example, terrestrial drones, ground sensors, or eVTOL vehicles).

Dealroom estimates that in August 2025, 29 space-tech companies raised a total of approx. $329.11m. As of publication, the dashboard also includes 4 additional deals, worth $29.58m, which we classify as either not space-tech, or not venture capital. The VentureSpace list this month includes four companies not listed on Dealroom’s dashboard at time of publication: Jeh Aerospace, Olee Space, Nullspace, and Inbound.
