Pre-Seed Funded Science and Engineering Startups
Across the 20 most recent pre-seed science and engineering rounds shown, the largest disclosed amount is $4M (Cloudline, 2023-08-16).
Across the 20 most recent pre-seed science and engineering rounds shown, the largest disclosed amount is $4M (Cloudline, 2023-08-16). That $4M round is above the rest of the disclosed amounts, which cluster mostly between $460K and $2M, with a few sub-$500K rounds such as Buildstash ($120K, 2024-09-09), Digital Earth Solutions ($160K, 2023-05-25), and Nanobiofab ($200K, 2025-01-21).
Dates form a dense middle window: 8 of the 20 rounds fall between 2024-02-20 (Connected, $2M) and 2024-07-01 (Lumen Orbit, $500K), while the list spans from the oldest entry in 2022-05-05 (Mako Aerospace, $700K) to the most recent on 2025-03-25 (Flight Science, $2M). Geography is dispersed rather than hub-like (cities include Los Angeles, London-range UK locations like Glasgow, and multiple European cities such as Madrid, Vienna, and Kosice), and disclosure is mixed: 3 rounds are undisclosed (WATS on 2023-04-12; SemiQon on 2023-03-14; plus an additional undisclosed row), creating a measurement gap around the extremes.

Frequently asked
What stands out about round sizes in this pre-seed science and engineering set?
The top disclosed round is Cloudline’s $4M (2023-08-16), which sits above the main band where most disclosed rounds land between roughly $460K and $2M (e.g., Flight Science $2M on 2025-03-25 and Sonus Microsystems $2M on 2024-02-26). Several smaller disclosed rounds also appear (Buildstash $120K on 2024-09-09; Digital Earth Solutions $160K on 2023-05-25; Nanobiofab $200K on 2025-01-21).
Are there clusters in the timeline of these rounds?
Yes. A concentration appears in mid-2024: 8 entries are between 2024-02-20 (Connected, $2M) and 2024-07-01 (Lumen Orbit, $500K), spanning roughly five months. Outside that window, the list extends from 2022-05-05 (Mako Aerospace, $700K) to 2025-03-25 (Flight Science, $2M), with fewer entries in early 2023 and late 2023.
How frequent are non-disclosed amounts, and do they affect outlier detection?
There are 3 pre-seed entries with undisclosed amounts: WATS (2023-04-12), SemiQon (2023-03-14), and one additional undisclosed row in the 20 shown. Because these are not included in disclosed-size comparisons, the apparent “top” and “bottom” only apply to disclosed amounts, with the lowest disclosed amount being Buildstash’s $120K (2024-09-09).
Is there a geographic pattern, or is the list broadly distributed?
The cities are broadly distributed rather than concentrated in a single metro: Los Angeles appears via Flight Science (2025-03-25), while multiple European locations show up separately such as Madrid (Digital Earth Solutions, 2023-05-25), Vienna (GATE Space, 2022-11-22), and Kosice (Nordics.io, 2024-12-13). The UK also appears more than once through Glasgow entries (Buildstash 2024-09-09 and Mako Aerospace 2022-05-05), but most other locations appear only once.
Which names highlight the “upper-middle” of disclosed funding in this list?
Several rounds sit at $2M, including Flight Science (2025-03-25), Sonus Microsystems (2024-02-26), and Connected (2024-02-20), suggesting a recurring ceiling below the $4M top. At the same time, the largest disclosed amount is still clearly separated from the rest: no other disclosed row equals $4M.
