# Space Tech Startups Showing Deceleration, Q3 2026

Startups whose 14-day commit velocity fell versus the prior window, a measurable slowdown that can mean a shipped milestone, a team transition, or a strategic pivot.

## Summary, Q3 2026

- 9 space tech startups currently match
- Top: open-space-collective, 48 commits/14d (-2%)

## Investor Insight

Deceleration is not automatically a red flag. A team that just shipped a major release often slows down to regroup. Read it alongside contributor growth and new repositories: falling velocity with stable or rising contributors usually means a finished push, while falling velocity and falling contributors together can flag turnover or a stalled roadmap.
