Across the 50 most recent science and engineering rounds shown, the largest disclosed amount is Electra.aero’s $115M (2025-04-21). That figure dwarfs the rest of the disclosed rounds, where the next-largest amounts cluster far lower (e.g., $60M for Quantum Space on 2025-02-19 and $50M for Next Level Aviation on 2024-12-10), and a long tail of sub-$10M rounds dominates (including Flight Science’s $2M on 2025-03-25 and Muuse’s $20K on 2023-06-27).

Frequently asked
Which disclosed round is the clearest outlier, and how far above the rest is it based on the disclosed amounts?
Electra.aero’s $115M on 2025-04-21 is the largest disclosed round in the table and sits well above the next-largest disclosed amounts such as Quantum Space at $60M (2025-02-19) and Recycle Track Systems at $40M (2025-01-24).
Do the rounds cluster in time near the top of the list, and what does that look like?
Yes. Multiple rounds fall in the most recent window: for example, from 2025-08-15 (Air Space Intelligence is $350K) and 2025-08-20 (Astro Mechanica is undisclosed) through 2025-04-21 (Electra.aero is $115M), with several disclosed rounds also landing in March 2025 (Flight Science $2M on 2025-03-25; Resource Chemical $15M on 2025-03-06; Mote $7M on 2025-03-04).
Where is there concentration by city or geography in this 50-row sample?
California-based entries appear repeatedly across the table: Los Angeles shows up with multiple companies/dates (Flight Science 2025-03-25; Mote 2025-03-04; Mitico 2025-02-25; Active Membranes 2024-07-09; Evolution Space is Mojave 2023-10-10; and C-Quester is Los Angeles 2023-06-21). Washington state also repeats via Seattle/Redmond (Starfish Space is Seattle 2024-11-13; Sky Harbour is White Plains, New York, but Lumen Orbit is Redmond 2024-10-25; Washington Maritime Blue is Seattle 2023-11-09).
What stage and funding-label mix dominates across these rows?
‘Series Unknown’ is the most common disclosed classification pattern: many entries list ‘Series Unknown’ (e.g., Air Space Intelligence 2025-08-15 with $350K; Resource Chemical 2025-03-06 with $15M; Recycle Track Systems 2025-01-24 with $40M). ‘Undisclosed’ amounts also recur (e.g., CisLunar Industries 2025-11-22; Astro Mechanica 2025-08-20; DART 2025-02-13), alongside named seed/pre-seed/Series A and Series B rounds like Electra.aero’s Series B ($115M, 2025-04-21).
Which entries sit at the extreme low end of disclosed funding, and how should that affect prioritization?
The smallest disclosed amount is Muuse at $20K on 2023-06-27, which is orders of magnitude below many disclosed rounds in the $1M–$10M band (e.g., Turnover Labs $1M on 2024-10-22; Vigilant Aerospace Systems $500K on 2024-05-09; Next Level Aviation $50M on 2024-12-10). That spread suggests a widening gap between ‘early experiment’ rounds and larger financings even within the same segment label.
