Frequently asked
Which entries are the disclosed outliers on amount and how extreme is the gap?
Multiverse Computing’s $570M disclosed round on 2026-07-27 is an outlier versus the rest; the next-largest disclosed amount is Adaptam Therapeutics’ $3M on 2025-10-29. At the low end, Miru Studio’s disclosed $100K (Seed, 2022-02-02) is the smallest of the 6 disclosed rows.
Is the city naming consistent, or are there two “Donostia” variants that could fragment matching?
The list contains two city spellings: “Donostia-san Sebastián” appears 5 times (e.g., Multiverse Computing $570M on 2026-07-27; TrebezIA $290K on 2026-06-16), while “Donostia-San Sebastián” appears 2 times (e.g., Ecomagnet $910K on 2022-05-09; Miru Studio $100K on 2022-02-02).
How concentrated are deal dates toward the most recent period?
There is a recent cluster in 2025–2026: Multiverse Computing closes 2026-07-27, TrebezIA follows 2026-06-16, and Adaptam Therapeutics closes 2025-10-29. The earliest row shown is Miru Studio on 2022-02-02, establishing a 2022-02-02 to 2026-07-27 date range for these 7 entries.
What does the stage mix look like across the disclosed amounts?
Pre-Seed appears once (Adaptam Therapeutics, $3M on 2025-10-29) while Seed appears multiple times with varying sizes, including Ecomagnet $910K (2022-05-09) and Miru Studio $100K (2022-02-02). “Series Unknown” shows up in at least two rows with disclosed amounts: Onena Medicines $550K (2023-10-06) and TrebezIA is Seed rather than unknown (so it does not add to that specific bucket).
Are specific sectors over-represented, and do they drive the largest rounds?
Biotechnology and healthcare/biopharma-related companies are a notable cluster: Adaptam Therapeutics (2025-10-29, $3M) and Onena Medicines (2023-10-06, $550K). The largest disclosed deal is in Software instead (Multiverse Computing, $570M on 2026-07-27), not in the biotech cluster.
Which recent entries fall into a short recency window, and what amounts characterize them?
Within the most recent year span in the table, the two late-2026 entries are Multiverse Computing ($570M, Series C, 2026-07-27) and TrebezIA ($290K, Seed, 2026-06-16). In 2025, the disclosed recency anchor is Adaptam Therapeutics at $3M on 2025-10-29, with Semi Zabala on 2025-11-25 listed as undisclosed.
