Across the 50 most recent seed rounds shown (sorted by round date descending), the largest disclosed amount is Maritime Fusion’s $5M on 2025-11-30, which is in the same high range as multiple other $4M–$7M rounds (for example, Opti $20M on 2025-11-27 and Onton $8M on 2025-11-29) but also coexists with a long tail of much smaller tickets like Empathium’s $10K on 2025-11-30. In terms of timing, the rows span 2025-11-20 to 2025-11-30, and the concentration is visible at the top of the window: several rounds land on 2025-11-30 (Empathium $10K; Maritime Fusion $5M; ThinkStream.ai $20K). Geographically, the list clusters strongly around major tech metros, with repeated San Francisco and New York entries across adjacent dates (e.g., Onton $8M and Maritime Fusion $5M in San Francisco on 2025-11-29 and 2025-11-30; Palo AI $4M and Social Links $3M in New York on 2025-11-24 and 2025-11-25). Sector-wise, Artificial Intelligence appears in 3+ entries and often overlaps with B2B software, cyber security, or analytics (for example, Opti, CoPlane, and Kestrel AI), while amounts marked undisclosed appear for 5 of the 50 rows (including Kestrel AI on 2025-11-23, CisLunar Industries on 2025-11-22, and QSimulate on 2025-11-20).

Frequently asked
What stands out in seed-round size among the most recent entries, and is there a clear outlier?
The largest disclosed round is Opti’s $20M on 2025-11-27, dwarfing the nearby disclosed ceiling of $10K–$8M tickets such as Empathium’s $10K (2025-11-30) and ThinkStream.ai’s $20K (2025-11-30), while other large disclosed rounds remain clustered below it (e.g., Onton $8M on 2025-11-29 and Mira $7M on 2025-11-28).
Are the most recent seed rounds concentrated into a narrow date window?
Yes. The page’s 50 rows run from 2025-11-20 (QSimulate, undisclosed) to 2025-11-30 (Empathium $10K, Maritime Fusion $5M, ThinkStream.ai $20K), with multiple same-day closings at the top—suggesting activity clustered near month-end rather than spread evenly.
Which cities show repeated concentration across adjacent dates?
San Francisco appears repeatedly at the high end of the date window, including Maritime Fusion ($5M, 2025-11-30), Onton ($8M, 2025-11-29), Mira ($7M, 2025-11-28), and Interface ($4M, 2025-11-25). New York also shows recurring entries in the same late-November run, such as CoPlane ($14M, 2025-11-26) and Social Links ($3M, 2025-11-25).
How should an analyst treat undisclosed amounts when comparing deal sizes?
Five of the 50 seed rounds are marked undisclosed (including Kestrel AI on 2025-11-23 and QSimulate on 2025-11-20). Any “largest/smallest” comparisons should be limited to disclosed amounts, since those undisclosed entries can’t be ordered (e.g., CisLunar Industries on 2025-11-22 is undisclosed).
Does the sector mix skew toward AI-related companies?
Artificial Intelligence appears across multiple entries with frequent overlap into B2B software, analytics, and security—examples include Opti (Cyber Security + AI) on 2025-11-27 ($20M), CoPlane (B2B Software + AI + Accounting/Finance) on 2025-11-26 ($14M), and Luminal (AI + Cloud Computing/Data + B2B Software) on 2025-11-21 ($5M).
