In this Series B–tagged set of 16 Science and Engineering rounds, Electra.aero’s $115M (2025-04-21) is among the larger financings, but it is the second-highest disclosed amount behind The Exploration Company’s $158M (2024-11-18). The top of the range sits close together ($158M, $115M, $107M, $73M), while several rounds cluster in the $16M–$40M band (e.g., Swoop Aero $16M on 2022-06-07; Swoop and Buildkite at $21M on 2022-11-15; Transcend Software $20M on 2023-08-03).
Timing and geography also show concentration. Dates span 2021-04-06 (Syzygy Plasmonics) through 2025-04-21 (Electra.aero), with four rounds in 2024 between 2024-11-18 and 2024-02-01 (The Exploration Company, Heart Aerospace, Latitude, and also the 2024-01-23/2024-02-01 entries). City concentration appears via multiple France-based rounds (Strapi $31M on 2022-06-22; Sweep $73M on 2022-04-04; Latitude $29M on 2024-01-23; VoltAero $33M on 2022-11-15). The smallest disclosed amount is $16M (Swoop Aero, 2022-06-07), making it materially below the mid-pack.

Frequently asked
Which disclosed round is the largest, and is anything dramatically above the rest?
The Exploration Company’s $158M on 2024-11-18 is the largest disclosed amount in these 16 rows. The next-largest disclosed amounts are $115M (Electra.aero, 2025-04-21) and $107M (Heart Aerospace, 2024-02-01), so the top end is clustered rather than separated by a single extreme outlier.
How concentrated are the financings in time—do the most recent rounds cluster in a narrow window?
Yes: four rounds fall in 2024, spanning from 2024-11-18 (The Exploration Company $158M) back to 2024-01-23 (Latitude $29M) and 2024-02-01 (Heart Aerospace $107M). The full date range covered by these rows runs from 2021-04-06 (Syzygy Plasmonics $23M) to 2025-04-21 (Electra.aero $115M).
Are any countries or cities over-represented in this Series B science/engineering list?
France shows up repeatedly: Latitude in Reims ($29M, 2024-01-23), Strapi in Paris ($31M, 2022-06-22), Sweep in Montpellier ($73M, 2022-04-04), and VoltAero in Médis ($33M, 2022-11-15). This concentration is stronger than single-entry geographies like the U.S. (Electra.aero $115M; Air Space Intelligence $34M on 2023-12-07).
Do the disclosed amounts cluster tightly, or are there clear low-end/upper-end groups?
There’s a clear mid/low grouping: multiple rounds land in the $16M–$40M range, including Swoop Aero $16M (2022-06-07), Swoop-related low-end Buildkite $21M (2022-11-15), Transcend Software $20M (2023-08-03), and Hystar $26M (2023-01-11). By contrast, the upper tier above $70M is rarer, led by The Exploration Company $158M, Electra.aero $115M, Heart Aerospace $107M, and Sweep $73M.
Which entries look most like outliers on the low end versus the high end?
On the low end, Swoop Aero’s $16M (2022-06-07) is the smallest disclosed amount in this set and sits well below many others clustered around $20M–$40M (e.g., Transcend Software $20M on 2023-08-03 and Air Space Intelligence $34M on 2023-12-07). On the high end, The Exploration Company’s $158M on 2024-11-18 is the standout, with the next-highest disclosed rounds not reaching the same level.
