By signal type in this sector
By stage
In Q4 2025, we are tracking 16 space tech startups with measurable GitHub engineering signals. 6 of 16 show positive commit velocity growth. The most common signal type is "Framework migration", observed in 10 of the tracked companies. The average 14-day commit velocity across the sector is 31 commits, with iff-gsc leading at 13 commits (+550% change). These patterns have historically preceded fundraise announcements by three to six weeks.
iff-gsc leads the space tech sector in Q4 2025 with 13 commits over a 14-day window, representing a +550% change from the prior period. With 5 active contributors, iff-gsc is showing a "Deploy frequency spike" pattern — one of the more reliable leading indicators of a significant product milestone or fundraise.
Among the 16 space tech startups we track, US accounts for the highest concentration with 3 teams. Startups building launch vehicles, satellites, and space data platforms. Geographic distribution matters for investors because engineering talent clusters correlate with sector-specific domain expertise and proximity to early adopter customers.
