Series B Funded Startups in United Kingdom
The largest disclosed Series B in this United Kingdom list is Nscale’s $1.1B round on 2025-09-26.
The largest disclosed Series B in this United Kingdom list is Nscale’s $1.1B round on 2025-09-26. That level dwarfs the next-largest disclosed amounts in the table (e.g., NRG Therapeutics at $68M on 2025-09-10, Dexory at $80M on 2024-10-01, and Xelix at $160M on 2025-07-21), with no other disclosed round approaching the $1B+ range.
Geographically, London dominates: every listed company is in London except i6 Group (Farnborough), OXCCU (Oxford), Alloyed (Yarnton), Cloudsmith (Belfast), Nodes & Links (London), and NatureMetrics (Guildford), with only UrbanChain based in Manchester (2024-12-16). Temporally, the 50 most recent rounds run from 2024-09-25 (Raycast and Apron) through 2025-11-23 (Vyntelligence), and the AI-labeled companies appear repeatedly across both the 2025-07 to 2025-09 window and later 2024 entries (e.g., Xelix 2025-07-21; 9fin 2024-12-02; Basecamp Research 2024-10-09). Two entries carry non-disclosed amounts: BVNK is marked “undisclosed” on 2025-05-06, while the smallest disclosed amount is Looper Insights at $5M on 2025-02-16.

Frequently asked
Which disclosed round looks like the clearest outlier, and how does it compare to the rest of the table?
Nscale’s $1.1B disclosed Series B on 2025-09-26 is the standout outlier; even the next-highest disclosed amounts—such as Xelix at $160M (2025-07-21) and Purespring Therapeutics at $105M (2024-10-09)—sit far below the $1B+ level.
Do these Series B rounds cluster in a specific geography within the UK?
London is heavily concentrated across the 50 rows (e.g., Vyntelligence $30M on 2025-11-23; Attio $52M on 2025-08-26; Dexory $80M on 2024-10-01). The main non-London locations are limited to a handful of entries such as OXCCU in Oxford ($28M on 2025-10-04), Cloudsmith in Belfast ($23M on 2025-03-03), and UrbanChain in Manchester ($63M on 2024-12-16).
What does the most recent part of the timeline look like—how late do the rounds go?
The latest round date shown is 2025-11-23, for Vyntelligence at $30M. Earlier in the same period, multiple rounds land in late 2025—such as PhysicsX $20M (2025-11-22) and OXCCU $28M (2025-10-04)—before the list rolls back to 2024-09-25 (Raycast $30M; Apron $29M).
Are there recurring sector themes across the list, based on what’s repeatedly labeled here?
Artificial Intelligence (AI) appears repeatedly across many different months and dates—for example PhysicsX ($20M on 2025-11-22), Nscale ($1.1B on 2025-09-26), Omnea ($50M on 2025-09-16), Skin Analytics ($20M on 2025-04-16), and 9fin ($50M on 2024-12-02). This creates an AI-heavy pattern versus single-appearance labels like Transportation (HIVED at $42M on 2025-07-03).
Any near-floor funding levels or non-disclosed rounds that might skew comparisons?
The smallest disclosed amount is Looper Insights at $5M on 2025-02-16, which is materially lower than many neighboring mid-teens to mid-$30M rounds (e.g., Wrisk $16M on 2025-07-08 and Bumper $11M on 2025-08-13). Separately, BVNK is explicitly “undisclosed” on 2025-05-06, so that entry cannot be used in disclosed-size comparisons.
