Across the 31 most recent funded entries tied to Tempe, the largest disclosed round is GT Medical Technologies at $100M (2026-06-09). That figure dwarfs the next-largest disclosed amounts in this slice, including $60M for Amtech Systems (2026-06-01) and $50M for Zero Mass Water (2020-06-17), with most other disclosed rounds concentrated below $46M (for example, Oats Overnight at $45M on 2026-01-29).

Sector-wise, Biotechnology appears repeatedly (Capstone Holding, Gut Brain Axis Therapeutics, and Calviri), while “Series Unknown” is common (counted in multiple rows, including Capstone Holding and Persefoni) and some rounds are explicitly undisclosed, such as ProPlaintiff.ai ($undisclosed on 2026-06-01) and DMD Systems ($undisclosed on 2025-09-18). Temporally, the shown dates span 2020-06-17 (Zero Mass Water) through 2026-06-12 (Capstone Holding), with Tempe remaining the geography across every row shown.

Frequently asked
What’s the largest disclosed round in this Tempe list, and how far above the rest is it?
GT Medical Technologies raised $100M on 2026-06-09, which stands well above other disclosed rounds in the same window, including $60M for Amtech Systems (2026-06-01) and $45M for Oats Overnight (2026-01-29). Several other disclosed amounts sit much lower, such as $1M for RadiusAI (2026-05-21) and $2M for Gut Brain Axis Therapeutics (2025-11-06).
Is there a tight clustering of round dates near the top of the list?
Yes. June 2026 contains 6 of the 31 entries, including Capstone Holding ($20M on 2026-06-12), GT Medical Technologies ($100M on 2026-06-09), and Amtech Systems ($60M on 2026-06-01). The list also remains active through early 2026, such as Wrap Technologies ($5M on 2026-02-02) and Oats Overnight ($45M on 2026-01-29).
Which sectors show up most often in these 31 rows?
Biotechnology appears multiple times, including Capstone Holding (Biotechnology; $20M on 2026-06-12), Gut Brain Axis Therapeutics (Biotechnology/Healthcare; Seed; $2M on 2025-11-06), and Calviri (Biotechnology; $790K on 2024-11-08). Other labels recur less consistently—for example, Energy shows up across several companies like Source ($130M on 2022-07-19), Erthos ($24M on 2023-09-11), and Zero Mass Water ($50M on 2020-06-17).
How much of the dataset is unclear due to “Series Unknown” or undisclosed funding amounts?
There are both classification and amount gaps: ProPlaintiff.ai lists an undisclosed amount on 2026-06-01, and DMD Systems lists an undisclosed amount on 2025-09-18. “Series Unknown” appears across multiple rows as well (for example, Capstone Holding on 2026-06-12 and Persefoni on 2026-05-01), which makes stage-based comparisons less reliable without those fields.
Are there notable outliers on the low end compared to the typical disclosed amounts?
Several disclosed rounds are far smaller than the largest entries: RadiusAI is disclosed at $1M (2026-05-21) and Purity ReSource is also $1M (2026-04-02), while the smallest disclosed amount in this slice is Deuterium Energetics at $100K (2021-06-03). Those values are small relative to the top disclosed rounds such as GT Medical Technologies at $100M (2026-06-09) and Source at $130M (2022-07-19).
