Across the 50 most recent funded startups listed for Madison, one disclosed round stands out: Cellectar Biosciences raised $35M on 2026-05-05, which sits far above other disclosed rounds in the table (the next-largest disclosed amounts are $27M on 2026-04-21 for Asto CT and $40M on 2025-11-06 for Elephas; all three are clustered within the top end of disclosed amounts). The page also shows a strong temporal clustering near the most recent filings: six entries land in a tight window from 2026-06-03 to 2026-04-30 (including Civic Media at $3M on 2026-06-03 and Calimetrix at $100K on 2026-06-08). Sector-wise, biotechnology appears repeatedly (e.g., Calimetrix 2026-06-08 $100K; Cellectar Biosciences 2026-05-05 $35M; Immuto Scientific 2025-09-19 $8M; Forward BIOLABS 2024-07-10 $190K), while the funding-size disclosure is uneven: “undisclosed” amounts appear on multiple rows (including Steam Instruments 2026-06-08; Carepool 2025-10-28). Geographically, nearly all rows are labeled Madison, Wisconsin, with one notable exception inside the city listing set: Sparta Biomedical is listed as Madison, New Jersey (2023-09-12, undisclosed). Dates span 2022-07-15 (Polco) through 2026-06-08 (Calimetrix and Steam Instruments).

Frequently asked
Which disclosed round is the outlier on this Madison list, and how does it compare to other large rounds?
Cellectar Biosciences’ $35M disclosed round on 2026-05-05 is a clear high-end outlier in the table, while other large disclosed rounds include Elephas at $40M on 2025-11-06 and Asto CT at $27M on 2026-04-21.
How concentrated are rounds around the latest part of the timeline (by date), and what does that imply for recency?
A dense cluster appears between 2026-06-08 and 2026-04-30, including Calimetrix ($100K, 2026-06-08), Civic Media ($3M, 2026-06-03), and Cellectar Biosciences ($35M, 2026-05-05). This indicates many of the “most recent” entries are concentrated in roughly a 6-week period.
Are “undisclosed” amounts common enough to affect analysis of deal size patterns?
Yes. Multiple rows show “undisclosed,” such as Steam Instruments (2026-06-08), EnsoData (2026-05-12), and Carepool (2025-10-28). That means the disclosed-size distribution is incomplete for a non-trivial share of companies.
Do certain sectors appear more often than others across these 50 rows?
Biotechnology is a recurring theme across multiple years and rounds, including Calimetrix (2026-06-08, $100K), Cellectar Biosciences (2026-05-05, $35M), GoDx (2025-02-23, $100K), and Cellular Logistics (2022-10-26, $340K). Other sectors do show up, but biotech is repeatedly represented in the listed companies.
Is there any notable geographic inconsistency within the “Madison” listings?
Nearly all entries are Madison, Wisconsin, but Sparta Biomedical is listed as Madison, New Jersey (2023-09-12) with an undisclosed amount, making it the standout geography mismatch within the dataset.
