Series A Funded Science and Engineering Startups
Across the 31 most recent Series A rounds in science and engineering, the largest disclosed amount is Quantum Source at $50M (2024-09-10).
Across the 31 most recent Series A rounds in science and engineering, the largest disclosed amount is Quantum Source at $50M (2024-09-10). That $50M figure ties with Silicon Quantum Computing ($50M on 2023-07-25) and sits notably above the next cluster of mid-$40Ms and $30Ms (e.g., MECAWARE at $42M on 2023-10-06 and Inversion Space at $44M on 2024-11-20), while the lower end includes multiple sub-$10M rounds such as 44.01 at $5M (2025-02-05) and Caeli Nova at $2M (2022-02-21).
The geography is globally distributed but with clear European density: London appears three times (44.01 on 2025-02-05, ORCA Computing on 2022-06-09, Caeli Nova on 2022-02-21), and the date window runs from 2021-07-13 (Heart Aerospace) to 2025-11-18 (AlixLabs). Several financings cluster in early 2023 (multiple March 2023 entries: Theion is 2025, but the 2023 set includes HT Materials Science on 2023-03-21, Strangeworks on 2023-03-21, and The Exploration Company on 2023-02-07), suggesting periodic momentum rather than a uniform spread.

Frequently asked
What stands out on round size among these Series A science and engineering deals, and how does it compare to the rest?
Quantum Source’s $50M (2024-09-10) is tied only by Silicon Quantum Computing’s $50M (2023-07-25); both are higher than the next-largest disclosed amounts like Inversion Space at $44M (2024-11-20) and MECAWARE at $42M (2023-10-06). At the low end, disclosed amounts fall to Caeli Nova’s $2M (2022-02-21) and 44.01’s $5M (2025-02-05).
Are there notable city concentrations in this list?
London shows up as a repeated location: 44.01 (London, 2025-02-05, $5M), ORCA Computing (London, 2022-06-09, $15M), and Caeli Nova (London, 2022-02-21, $2M). Beyond London, the US also reappears multiple times (e.g., Inversion Space in Los Angeles, $44M on 2024-11-20; ClimateAI in San Francisco, $12M on 2021-07-21; Heart Aerospace in Göteborg, Sweden appears once, but the US entries are distributed across multiple states).
Which deals are closest to the current edge of the date range shown?
The most recent round is AlixLabs on 2025-11-18 at $16M. Within the most recent 90 days of that date, the list includes Qedma (2025-07-03, $26M), Theion (2025-03-19, $16M), and Pangea Aerospace (2025-03-18, $25M), plus Mote (2025-03-04, $7M) and 44.01 (2025-02-05, $5M).
Do the amounts cluster in a specific band rather than spreading evenly?
Yes—there’s a clear concentration in the mid-range of disclosed amounts: Starfish Space at $29M (2024-11-13), Quantum Source at $50M (2024-09-10), MECAWARE at $42M (2023-10-06), and The Exploration Company at $43M (2023-02-07) sit alongside multiple $35M–$44M outcomes such as Heart Aerospace at $35M (2021-07-13) and Space Perspective at $40M (2021-10-14). Smaller outflows below $10M include Vibrant Corporation at $3M (2023-07-18) and GreenSpark Software at $5M (2021-12-20).
Are there any outliers that merit separate attention?
Caeli Nova’s $2M (2022-02-21) is the smallest disclosed amount in the table, materially below the broader set where many entries are in the $10M–$30M range (e.g., Verica at $12M on 2022-01-18 and Last9 at $11M on 2022-04-12). On the high side, the only disclosed amounts at $50M are Quantum Source (2024-09-10) and Silicon Quantum Computing (2023-07-25), which frame the top-end of the distribution.
