Frequently asked
What stands out on round size, and is there a clear top end versus the rest?
Great Bay Royalties’ $73M (2026-06-15) is the top disclosed amount and the only round above $50M; Vatn Systems’ $60M (2025-12-10) is the next-largest disclosed amount. After that, disclosed rounds mostly sit in the $2M–$20M band, with smaller disclosed entries like BioGreen360’s $200K (2023-05-01).
Are Portsmouth-area rounds concentrated in a narrow recent window?
Yes. Three disclosed rounds land within the same window from 2025-10-03 to 2026-06-15: HELIOS ($2M, 2025-10-03), Vatn Systems ($60M, 2025-12-10), and Great Bay Royalties ($73M, 2026-06-15). The oldest dated entry in the 11-row slice is Bit Fry Game Studios at $1M on 2022-12-20.
Which “Portsmouth” locations dominate, and do the out-of-state entries change the pattern?
Portsmouth, New Hampshire is over-represented in this list, including Vatn Systems ($60M, 2025-12-10) and Position Imaging ($20M, 2023-12-20). The non–New Hampshire entries are sparse but distinct by geography and often by size—for example, Mercy Chefs is in Portsmouth, Virginia at $250K (2025-07-22) and Surv is in Portsmouth, Rhode Island at $160K (2022-11-14).
How does the stage mix look across these 11 entries?
“Series Unknown” appears 5 times (including Great Bay Royalties on 2026-06-15 and Mercy Chefs on 2025-07-22). Seed appears 2 times (HELIOS $2M on 2025-10-03 and Remotely $500K on 2022-03-03), Pre-Seed appears once (River Platform Company $2M on 2024-10-15), and one entry is undisclosed (Searchlight Cyber on 2024-01-18).
Are there notable sector clusters, or does industry dispersion limit patterning?
No single sector repeats enough to form a 3+ entry cluster in this slice. Examples include Information Technology with two entries (Vatn Systems $60M on 2025-12-10 and Remotely $500K on 2022-03-03), plus one-off sectors like AI (HELIOS $2M, 2025-10-03) and Energy (Great Bay Royalties $73M, 2026-06-15).
Is there a meaningful smallest disclosed round or an undisclosed outlier worth flagging?
The smallest disclosed amount shown is $160K for Surv (2022-11-14) and the list also contains one undisclosed amount: Searchlight Cyber in Portsmouth, Hampshire, United Kingdom (2024-01-18). Size-wise, that undisclosed row sits in the middle of the time span, but it cannot be compared on amount because no dollar figure is provided.
