In the 39 most recent funded rounds shown for Woburn, the largest disclosed amount is Phoenix Tailings at $500M (2026-06-16), which dwarfs every other disclosed round in this window (the next-highest disclosed amount is $275M from SES on 2022-02-04). Several entries also cluster in late 2025: Sanegene Bio closes $110M (2025-12-08) and Zumutor Biologics closes $7M (2026-06-13) sits in the same broader “recent” band, while multiple biotechnology and energy rounds fall between 2025-11-18 and 2026-02-11.
Sector mix skews toward biotechnology and health-related categories: biotechnology appears in at least 10 entries (e.g., Zumutor Biologics $7M on 2026-06-13; Sanegene Bio $110M on 2025-12-08; Replimune Group $140M on 2024-11-25), and healthcare appears in multiple rounds including Ossio $40M (2026-02-11) and Barricaid $56M (2023-12-08). Stage disclosure is frequently incomplete: 12 entries are “undisclosed” by amount and another large share is “Series Unknown” (e.g., Factorial Energy $100M on 2026-06-08; Boston Metal $75M on 2026-05-20). Dates span from 2020-08-13 (Root AI, $7M) through 2026-06-16 (Phoenix Tailings).

Frequently asked
What stands out on round size in Woburn—does one disclosed deal dwarf the rest?
Yes. Phoenix Tailings’ $500M (2026-06-16) is the largest disclosed amount in the table and is far above the next-largest disclosed round of $275M (SES on 2022-02-04). Most other disclosed rounds sit well below that top pair, including $140M (Replimune Group on 2024-11-25) and $110M (Sanegene Bio on 2025-12-08).
Do recent funding rounds cluster into a narrow time window?
There is a notable late-2025-to-early-2026 concentration. Examples include Nanoramic Laboratories at $54M (2025-11-18), Sanegene Bio at $110M (2025-12-08), Hopewell Therapeutics at $3M (2025-09-21), and Ossio at $40M (2026-02-11), all within a handful of months of each other relative to older entries like Root AI on 2020-08-13 ($7M).
Which sectors are most over-represented in this Woburn list?
Biotechnology is the most frequent sector, appearing in at least 10 entries such as Zumutor Biologics (Series B, $7M on 2026-06-13), Sanegene Bio ($110M on 2025-12-08), Replimune Group ($140M on 2024-11-25), and MarvelBiome ($40M on 2025-10-22). Healthcare also shows repeated presence through Ossio ($40M on 2026-02-11) and Barricaid ($56M on 2023-12-08).
How much of the list has incomplete deal disclosure (amount or series)?
Amount disclosure is incomplete in multiple rows: 12 entries show “undisclosed” amounts (e.g., 100XBIO on 2025-12-27; Leveragen on 2025-07-25; Frequency Therapeutics on 2022-08-15). Separately, many rounds use “Series Unknown” classifications even when amounts are disclosed, such as Factorial Energy ($100M on 2026-06-08) and Boston Metal ($75M on 2026-05-20).
Are there outliers besides the largest round—for example, unusually small disclosed amounts or unusual stage/sector combinations?
Imago Rehab is a small disclosed outlier at $250K (2024-07-08) compared with most other disclosed rounds in the table. On the high end, Phoenix Tailings’ $500M (2026-06-16) stands apart not only by size but also by having a “Series Unknown” label in the dataset, unlike several mid-to-late deals that specify stages such as Series B or Series C (e.g., Neurogastrx $60M on 2021-08-26, Series B; Alsym Energy $78M on 2024-04-03, Series C).
