Across the 23 most recent Series D hardware rounds shown, the largest disclosed amount is Nuro’s $600M on 2021-11-02, which dwarfs the rest of the disclosed figures (with several others clustered far below it, such as Exotec at $337M on 2022-01-17 and BigPanda at $190M on 2022-01-12). At the other end, the smallest disclosed amount is Federated Wireless at $14M on 2022-05-02, sitting well under the next-lowest disclosed rounds like Boston Micro Fabrication’s $22M (2023-06-13) and Neocis’s $20M (2024-01-10).
The date window spans 2021-01-28 (OwnBackup) through 2025-06-25 (EFFECT Photonics), with the most recent entry in June 2025 and the older edge in January 2021. Geographically, the list is split across multiple countries but shows a clear concentration in the United States: several of the biggest disclosed rounds are US-based (e.g., Astranis $200M in San Francisco, Nuro $600M in Mountain View, and Neptune Medical $97M in Burlingame). Undisclosed amounts appear twice in this view (Varjo on 2024-11-25 and Worldsensing on 2023-03-22), shaping comparisons by limiting the visible “top” and “bottom” within disclosed figures only.

Frequently asked
Which disclosed Series D round is the outlier on size, and how separated is it from the rest of the disclosed amounts?
Nuro’s $600M round on 2021-11-02 is the clear size outlier; the next-largest disclosed amounts in this table are Exotec’s $337M (2022-01-17) and BigPanda’s $190M (2022-01-12), leaving a large gap from the rest of the distribution.
How does the smallest disclosed round compare to other low-disclosed entries in this hardware set?
The smallest disclosed amount is Federated Wireless at $14M on 2022-05-02. The next-lowest disclosed rounds visible are Neocis at $20M (2024-01-10) and Boston Micro Fabrication at $22M (2023-06-13), placing $14M noticeably below the lower cluster.
Are there notable temporal clusters among the most recent hardware Series D rounds shown?
Yes: multiple rounds land in early 2022 and early 2024. Early 2022 includes InterCloud $114M (2022-02-15), LeddarTech $116M (2022-02-03), and BigPanda $190M (2022-01-12), while early 2024 includes Neocis $20M (2024-01-10) and Ursa Major $100M (2024-04-26) plus Fleet Space Technologies $100M later in 2024 (2024-12-11), indicating at least two dense periods rather than evenly spaced dates.
Which geography is most represented here, and do the largest disclosed rounds align with that geography?
The United States accounts for a substantial share of entries, including several of the largest disclosed rounds: Nuro ($600M, Mountain View) and Astranis ($200M, San Francisco) appear alongside Neptune Medical ($97M, Burlingame). Other countries appear (e.g., France with Wandercraft $75M on 2025-06-06 and Exotec $337M on 2022-01-17; Australia with Fleet Space Technologies $100M on 2024-12-11), but the biggest disclosed figures in this view are primarily US-based.
How many rounds have undisclosed amounts in this Series D hardware list, and do they affect which companies sit at the top or bottom?
There are two undisclosed-amount rows in the 23 shown: Varjo (2024-11-25) and Worldsensing (2023-03-22). Because “largest” and “smallest” comparisons here use disclosed values, these undisclosed rounds cannot be confirmed as top or bottom against the disclosed extremes (Nuro $600M and Federated Wireless $14M).
