Across these 50 UK Series A rounds, the largest disclosed amount is $100M for CuspAI on 2025-09-09; it sits well above the rest, with the next-largest disclosed amounts including Trogenix ($94M, 2025-10-11) and Wild Bioscience ($60M, 2025-10-13). The smallest disclosed round is $400K for Little Journey (2025-07-17), creating a wide disclosed spread that includes multiple $3M–$10M rounds (for example, Dune $3M on 2025-11-05; OBT Live $3M on 2025-06-05).
Most rounds cluster in London: 33 of the 50 entries list London (e.g., Hyperlayer $40M on 2025-10-15; Tonic Health $4M on 2025-07-01), while Cambridge appears repeatedly (PACT $21M on 2025-10-31; T-Therapeutics $32M on 2025-11-15; CuspAI is Cambridge $100M on 2025-09-09). Dates span from 2025-05-08 (Ravio) through 2025-11-28 (Whitespace). Disclosed sizing is incomplete: 4 entries are marked undisclosed (Ryft 2025-09-14; KASA Tech 2025-09-17; Quant Insight 2025-07-16; usecure 2025-07-02; ReVentas 2025-05-26), and AI-related labels appear in 11+ entries (e.g., Hyperlayer $40M on 2025-10-15; Maze $25M on 2025-06-10; Gradient Labs $13M on 2025-07-08).

Frequently asked
Which disclosed Series A rounds are outliers in size, and how do they frame the rest of the list?
CuspAI’s $100M on 2025-09-09 is the largest disclosed amount and dwarfs the next-largest disclosed rounds, including Trogenix at $94M on 2025-10-11 and Wild Bioscience at $60M on 2025-10-13. On the low end, Little Journey’s $400K on 2025-07-17 is the smallest disclosed amount, far below the $3M–$10M cluster seen in entries like Dune ($3M on 2025-11-05) and OBT Live ($3M on 2025-06-05).
Is London a meaningful hub in this Series A slice, or is funding spread across many UK cities?
London dominates the geography: 33 of 50 rows list London (e.g., Deblock $35M on 2025-11-18; PolyModels Hub $9M on 2025-11-23; Yaspa $12M on 2025-07-02). Cambridge also appears as a concentrated secondary node with multiple entries such as PACT ($21M on 2025-10-31) and T-Therapeutics ($32M on 2025-11-15), indicating a bifurcation between London and a smaller biotech/AI cluster in Cambridge.
How concentrated are these rounds within the displayed time window?
The displayed Series A rounds span from 2025-05-08 (Ravio) to 2025-11-28 (Whitespace). Several high-dollar rounds land in late September to early October—CuspAI ($100M, 2025-09-09), Tern Group ($24M, 2025-09-09), Trogenix ($94M, 2025-10-11), and Wild Bioscience ($60M, 2025-10-13)—suggesting a mid-to-late summer/early autumn concentration in both size and timing.
Are there sector themes that show up frequently across the 50 rounds?
Artificial Intelligence appears in 11+ entries, spanning multiple business models and funding sizes: Hyperlayer ($40M on 2025-10-15), Maze ($25M on 2025-06-10), and Gradient Labs ($13M on 2025-07-08) all carry AI among their labels. Biotechnology also recurs often (e.g., PolyModels Hub $9M on 2025-11-23; Wild Bioscience $60M on 2025-10-13; T-Therapeutics $32M on 2025-11-15), pairing with the London/Cambridge geographic split.
Do undisclosed amounts limit size comparisons, and where do those missing disclosures appear?
Yes—5 entries are marked undisclosed, including Ryft (2025-09-14), KASA Tech (2025-09-17), Quant Insight (2025-07-16), usecure (2025-07-02), and ReVentas (2025-05-26). These gaps sit alongside otherwise disclosed rounds that range from $400K (Little Journey on 2025-07-17) up to $100M (CuspAI on 2025-09-09), so the disclosed distribution is informative but not complete.
