Across these 50 “Venture - Series Unknown” entries, the largest disclosed round is Sidewalk Infrastructure Partners at $100M (2025-11-04), and it stands well above the rest of the disclosed amounts; the next-highest disclosed entries cluster much closer to the top (e.g., Common Ground at $52M on 2022-08-03 and X Shore at $50M on 2022-04-05), while many rounds sit in the low-to-mid single digits or teens (e.g., Wrench at $470K on 2022-05-13; Auxilia at $1M on 2025-09-13).
Timing and geography are less random than they look: the most recent activity spans 2022-02-15 through 2025-11-24, but the bulk of disclosed rounds concentrates in mid-2022 (e.g., multiple June–August 2022 entries such as Common Ground $52M on 2022-08-03 and Euler $32M on 2022-06-07). City patterns also appear repeatedly in the US and UK, with several entries in New York (e.g., Evidence Partners at $16M on 2022-08-09; BEAT THE BOMB at $7M on 2022-06-28; Alfred at $50M on 2022-03-08). Disclosures are uneven: 6 of 50 rows list amounts as undisclosed (including Alchemy on 2025-11-24 and Loloft on 2022-10-22), and only one amount is notably smallest among disclosed rounds: $100K appears multiple times (e.g., Aglet on 2022-03-01; Idaho College of Osteopathic Medicine on 2022-02-22; Zand on 2022-02-15).

Frequently asked
What’s the biggest disclosed “Venture - Series Unknown” round in this list, and how far ahead is it?
Sidewalk Infrastructure Partners is the outlier at $100M on 2025-11-04. The next-highest disclosed amounts are in the same general upper range but well below it, such as Common Ground at $52M (2022-08-03) and X Shore at $50M (2022-04-05).
Do the dated rounds cluster in a particular time window rather than spreading evenly from 2022 to 2025?
The rows span 2022-02-15 to 2025-11-24, but many entries cluster in mid-2022, particularly around June–August 2022 (e.g., Euler $32M on 2022-06-07; CORDIO Medical $18M on 2022-06-27; Common Ground $52M on 2022-08-03). The latest two disclosed-size datapoints include Auxilia at $1M on 2025-09-13 and Sidewalk Infrastructure Partners at $100M on 2025-11-04.
Are any cities repeatedly represented in the top geography, suggesting a concentration?
New York shows up multiple times with different round sizes, including Evidence Partners at $16M (2022-08-09), BEAT THE BOMB at $7M (2022-06-28), and Alfred at $50M (2022-03-08). The UK also recurs via London entries such as Electric Car Scheme at $3M (2022-09-21), Euler at $32M (2022-06-07), and Rungway at $4M (2022-04-11).
How much of the list is undisclosed, and does that affect identifying outliers?
6 of 50 rows are “undisclosed” (e.g., Alchemy on 2025-11-24; Loloft on 2022-10-22; Assetario on 2022-04-06). Even with those gaps, the largest disclosed amount remains clearly identifiable at $100M (Sidewalk Infrastructure Partners, 2025-11-04), while the smallest disclosed amount is $100K appearing multiple times (Aglet 2022-03-01; Idaho College of Osteopathic Medicine 2022-02-22; Zand 2022-02-15).
Which entries act as low-end and mid-pack anchors for the disclosed amount distribution?
At the low end, Wrench is an extreme small disclosed datapoint at $470K (2022-05-13), and several $1M–$5M rounds appear across the period (e.g., Auxilia $1M on 2025-09-13; Arise Travel $3M on 2022-08-16). On the mid-to-upper side, “upper tier” rounds cluster around tens of millions, such as Lumos at $30M (2022-05-03) and Carbar at $29M (2022-02-15), before the $52M–$100M range takes over at the top.
