Disclosed round sizes in Zurich skew heavily toward a single outlier: Climeworks raised $162M (2025-07-02), dwarfing the next-largest disclosed rounds above $100M, including Auterion’s $105M (2025-09-24) and Flexion Robotics’ $50M (2025-11-18). The smallest disclosed amount is $30K, appearing twice (Aurora Analytics on 2025-07-23 and Impact.build on 2025-07-23), while several other rounds cluster in the low millions (for example, Qala at $2M on 2025-10-29; DuraMon at $2M on 2025-03-03; CellX Biosolutions at $2M on 2025-02-25).
The most recent row is K2 Photonics with an undisclosed round on 2025-11-29, and the earliest shown date is Resmonics on 2025-01-16. Timing is concentrated: nine rounds between 2025-11-02 and 2025-10-30 (including Tethys Robotics $4M on 2025-11-02 and Loonawell $460K on 2025-10-30), with most listings explicitly tied to “Zürich” or “Zürich, Zurich” on the same city line. Stage/label mix is also uneven: “Series Unknown” appears in 11 entries, and “undisclosed” appears in 2 entries (K2 Photonics 2025-11-29; Arktis Radiation Detectors 2025-04-23; SynSense 2025-01-22).

Frequently asked
What stands out in Zurich on deal size: what’s the largest disclosed round, and how does it compare to the rest?
Climeworks’ $162M on 2025-07-02 is a clear outlier; the next-largest disclosed rounds in this view are Auterion at $105M (2025-09-24) and Flexion Robotics at $50M (2025-11-18), with most other disclosed amounts clustered well below $50M.
Are there any tight timing clusters in the most recent Zurich funding activity?
Yes. From 2025-11-12 to 2025-11-02 there’s a dense run of five entries (Omnilex $5M on 2025-11-12; mimic $16M on 2025-11-07; DeepJudge $42M on 2025-11-06; Tethys Robotics $4M on 2025-11-02), and 2025-10-31 to 2025-10-29 adds more activity (Obligate $3M on 2025-10-31; Qala $2M on 2025-10-29).
Which stages/labels dominate, and how often are amounts missing or labeled without a stage?
“Series Unknown” shows up 11 times (e.g., Obligate $3M on 2025-10-31; Candi $20M on 2025-07-21; Positrigo $9M on 2025-06-10), while “undisclosed” appears 2 times (K2 Photonics on 2025-11-29; Arktis Radiation Detectors on 2025-04-23; SynSense on 2025-01-22 are also listed as undisclosed).
Do specific sectors appear repeatedly across the Zurich list, suggesting concentration?
Artificial Intelligence (AI) appears across many entries, spanning multiple stages and dates (Cerrion $18M on 2025-11-24; Flexion Robotics $50M on 2025-11-18; DeepJudge $42M on 2025-11-06; Omnilex $5M on 2025-11-12; multiple Pre-Seed/Seed AI companies like Qala $2M on 2025-10-29).
Are there any strong small-end or ultra-small outliers among disclosed amounts in this view?
The smallest disclosed amount is $30K, occurring twice on 2025-07-23 (Aurora Analytics and Impact.build). That low floor sits alongside multiple sub-$1M rounds such as Loonawell’s $460K on 2025-10-30 and JOSEPHA’s $190K on 2025-04-22, making early-stage funding sizes noticeably more varied than mid-sized disclosed deals.
