Among the 46 listed Princeton-area funded rounds, the largest disclosed amount is Essential Properties’ $400M (2026-06-04). That figure dwarfs the next-largest disclosed rounds in the table (QuantX Biosciences $85M on 2026-02-09; Thea Energy $100M on 2026-05-27; Miami International Holdings $318M on 2025-12-11; IVERIC bio $250M on 2022-07-26), while many other disclosed rounds cluster near the $2M–$20M range (for example, Exafluence $2M on 2023-02-15 and Transcend Software $20M on 2023-08-03).
The most recent entry is Optimeos Life Sciences (undisclosed) on 2026-06-25, and the date span runs from 2020-11-05 (Tetrels Technology Corp.; $15M) to 2026-06-25. Disclosed amounts are often missing: 20 of 46 rows are “undisclosed” and another 13 are labeled “Series Unknown,” indicating that stage disclosure is incomplete even across the newest months (e.g., Crosslayer Labs on 2026-04-14 is undisclosed). Sector-wise, Biotechnology, Health Care, Energy, and Financial Services each recur multiple times, with Biotechnology showing a particularly long presence from 2026 (e.g., BlinkLab $13M on 2026-04-15) back through earlier years (e.g., Advaxis $5M on 2022-02-10).

Frequently asked
What does the size distribution look like—are there clear outliers in disclosed amounts?
Essential Properties’ $400M round (2026-06-04) is an extreme outlier versus the rest of the disclosed amounts, with the next tier including Miami International Holdings’ $318M (2025-12-11) and Thea Energy’s $100M (2026-05-27). Outside that top range, many disclosed rounds sit closer together (e.g., $9M Soligenix on 2023-05-05 and $20M Transcend Software on 2023-08-03).
Are most funding rounds concentrated in a narrow recent window, or spread evenly across years?
The table spans 2020-11-05 (Tetrels Technology Corp.; $15M) through 2026-06-25 (Optimeos Life Sciences; undisclosed). It does show a recent-heavy stretch in mid-2026, such as multiple entries from 2026-06 (Essential Properties $400M on 2026-06-04; Ingenuity Trading $5M on 2026-06-09; Optimeos Life Sciences undisclosed on 2026-06-25), but the list also contains older, high-impact rounds like IVERIC bio $250M (2022-07-26).
How complete is stage disclosure in this Princeton list—what fraction is missing or unclear?
Stage and amount clarity is limited: 20 of 46 rows are “undisclosed” and 13 of 46 are labeled “Series Unknown.” The same pattern appears in the newest entries (e.g., Andluca Seed on 2026-06-22 is undisclosed; Latent AI on 2026-03-03 is undisclosed), so interpreting “latest” by stage alone is constrained.
Which sectors appear frequently enough to form a cluster rather than being incidental?
Several sectors repeat multiple times across the time window, notably Biotechnology (e.g., BlinkLab $13M on 2026-04-15; QuantX Biosciences $85M on 2026-02-09; Sonnet BioTherapeutics on 2024-11-06 with $5M). Health Care also shows recurring presence (Populus Health Technologies $5M on 2024-11-12; Care IO Seed on 2024-11-26 undisclosed), while Energy and Financial Services recur as well (e.g., Thea Energy $100M on 2026-05-27; Ingenuity Trading $5M on 2026-06-09; Miami International Holdings $318M on 2025-12-11).
Which geography-related pattern stands out—are all entries in the same place, or are there notable variants?
Nearly all entries specify Princeton, New Jersey, with one clear geographic variant: Optimi Health is listed as Princeton, British Columbia, Canada (2026-05-20) with a $15M amount. That single non-NJ Princeton entry is a geographic outlier relative to the otherwise consistent Princeton, New Jersey labeling.
Are there particular stages or deal types that dominate the disclosed rounds, versus many small/unknown deals?
Disclosed amounts include large late-stage and growth rounds (e.g., Thea Energy Series B $100M on 2026-05-27 and QuantX Biosciences Series B $85M on 2026-02-09), but many entries remain small-to-mid and a large share is not disclosed at all. Even among disclosed Seed rounds, amounts vary (Navikenz Seed $8M on 2026-02-17 vs. Populus Health Technologies Seed $5M on 2024-11-12), while several of the newest Seed entries show undisclosed amounts (e.g., Optimeos Life Sciences 2026-06-25 undisclosed; Crosslayer Labs 2026-04-14 undisclosed).
