Across the 50 most recent “Series Unknown” design rounds, the largest disclosed amount is Flipspaces’ $35M on 2025-05-07, and it stands well above the rest of the disclosed figures (multiple rounds cluster in the $1M–$13M band, while only a few exceed $20M such as Druid Software at $20M on 2025-01-08 and Knapsack at $11M on 2025-05-02). The list also shows a temporal build-up in mid-2024 to mid-2025: many entries fall between April 2024 and August 2024, and the newest row is Babyark (Dover, Delaware) on 2025-08-25.
Geographically, the dataset is globally distributed rather than concentrated in a single metro (cities like London appear via both Atelier in 2025-02-27 and Deverium in 2024-09-11, but there is no single dominant hub). Amounts are frequently undisclosed: 12 of the 50 rows show “undisclosed,” which creates a sharper contrast between the small disclosed rounds (for example Audientes at $80K on 2025-05-02) and the disclosed high-end. Sector naming is consistent (“Design” across all rows), while the stage label is uniformly “Series Unknown.”

Frequently asked
What’s the largest disclosed round in this “Series Unknown” design slice, and how far above the rest is it?
Flipspaces’ $35M on 2025-05-07 is the top disclosed amount in the 50-row window. That level is substantially higher than most other disclosed rounds, which frequently sit in the $1M–$13M range (for example Soluna at $5M on 2025-07-15 and Druid Software at $20M on 2025-01-08 as another higher-but-lower-than-Flipspaces benchmark).
Are the rounds clustered by date, or do they spread evenly across the window shown?
They’re not evenly distributed: many entries concentrate in a long mid-range from April–August 2024 and continue into the first half of 2025, with frequent filings on specific April 2024 dates such as 2024-04-03 (Codejet $150K, Flowstep $1M, and Metalbook $3M). The newest row is Babyark on 2025-08-25, while the oldest dates shown run back to 2024-02-01 (Hixson $500K).
Which cities show any repeat presence, and is there evidence of a single dominant hub?
There’s limited repeat geography rather than a dominant hub. London appears at least twice via Atelier on 2025-02-27 (undisclosed) and Deverium on 2024-09-11 ($2M), but most other entries are single-instance across diverse locations such as Stockholm (Candela $8M on 2025-08-13) and Palo Alto (LottieFiles undisclosed on 2024-05-08).
How often are amounts undisclosed, and does that change how to interpret the highs and lows?
“Undisclosed” appears 12 times out of 50 rows, so comparisons of “largest” and “smallest” apply only to disclosed amounts. Among disclosed figures, the smallest is Audientes at $80K on 2025-05-02, which highlights a wide spread versus the disclosed top end like Flipspaces at $35M on 2025-05-07.
Which entries closed within the most recent 90 days of the listing window, based on the dates shown?
Using the newest date shown (2025-08-25) as the reference, entries in the prior ~90 days include Babyark (2025-08-25, $2M), Candela (2025-08-13, $8M), Wuilt (2025-08-04, $2M), Lazenby Group (2025-07-24, $880K), Soluna (2025-07-15, $5M), and Eco Wave Power (2025-07-10, $3M). Several of these are disclosed, while at least one nearby entry remains undisclosed (for example Ickler Electric on 2025-06-12).
