Disclosed funding in this Boston “Other” list is concentrated around low-to-mid single-digit millions, with one clear exception: P0x Labs’ $25M Series A on 2023-07-19 stands well above the rest of the disclosed rounds (the next-largest disclosed amounts are $20M by Oxygen Esports on 2022-04-14 and $10M by Slate Milk on 2024-09-05). The outlier pattern is reinforced by the smallest disclosed rounds: Plutoview at $300K (2021-08-05) and, close behind, Seahawk at $100K (2021-04-01).
Timing is also clustered within the covered window. Rounds span 2020-09-10 (Tally Street, $800K) through 2025-05-12 (Toys for Tots, undisclosed), with the most recent four dated entries falling between 2024-09-05 (Slate Milk, $10M) and 2025-05-12 (Toys for Tots). Stage and disclosure skew toward non-standard labels: 5 of 16 rows are “Series Unknown” and 1 is “undisclosed,” while the remaining disclosed stages include Seed, Pre-Seed, Angel, and multiple Series A rounds (e.g., Velma’s $3M Seed on 2024-01-05 and Oxygen Esports’ $20M Series A on 2022-04-14).

Frequently asked
What’s the largest disclosed round in Boston for the “Other” segment here, and how much bigger is it than the rest?
P0x Labs’ $25M Series A on 2023-07-19 is the only disclosed round above $20M in these 16 rows; the next-largest disclosed amounts are $20M (Oxygen Esports, 2022-04-14) and $10M (Slate Milk, 2024-09-05). That makes the top disclosed round clearly larger than the rest of the disclosed figures.
Are most of these funding rounds clustered in time, or are they evenly spread across years?
They’re spread across 2020-09-10 to 2025-05-12, but there is visible recency concentration: the last four dated entries are from 2023-07-19 (P0x Labs, $25M), 2024-01-05 (Velma, $3M), 2024-09-05 (Slate Milk, $10M), and 2025-05-12 (Toys for Tots, undisclosed).
How heavy is disclosure uncertainty in this list (Series Unknown vs undisclosed), and how does it affect comparing round sizes?
5 of 16 rows are labeled “Series Unknown” (e.g., Slate Milk is actually labeled $10M but Series Unknown; Benjamin Franklin Institute of Technology is “Series Unknown” at $3M on 2023-04-27), and 1 of 16 is “undisclosed” (Toys for Tots on 2025-05-12). That leaves fewer labeled, comparable disclosed amounts when ranking by size.
Which stages or round types show up most often among the labeled rounds?
Series A appears repeatedly with P0x Labs ($25M, 2023-07-19), Oxygen Esports ($20M, 2022-04-14), Ark PES ($3M, 2021-04-07), plus earlier Series A examples like (also) at $3M for Ark PES. Seed also appears more than once (Velma $3M on 2024-01-05; Seaspire Skincare $3M on 2022-05-05; Seahawk is Seed at $100K on 2021-04-01).
Are there low-end outliers worth attention when reviewing disclosed amounts?
Yes. The smallest disclosed amount is Seahawk’s $100K Seed round on 2021-04-01, followed by Plutoview’s $300K Angel round on 2021-08-05. Both sit far below the dominant cluster of $2M–$5M disclosed rounds such as Bldup ($2M, 2021-08-10), Seaspire Skincare ($3M, 2022-05-05), and Jobs for the Future ($5M, 2022-08-08).
