Fifth Dimension led the pack at $26M, followed by Gizmo at $22M and Adfin at $18M. Two of the three deals went to AI-native companies, and all three list London as headquarters. The Series A activity sat against a much larger late-stage week. UK Series B+ rounds totaled $2.17B across two deals, dominated by Isomorphic Labs and another deeptech raise. That gap between $66M at growth-stage and $2.17B at scale-up tells a familiar story for London right now: capital is concentrated in proven AI bets, while Series A is funding the next wave of vertical specialists trying to follow that path.

Fifth Dimension Raises $26M For AI Decision Intelligence ### Deal Overview - Stage: Series A - Sector: AI / Real Assets - Geography: London, UK (offices in NYC and Singapore) - Round size: $26M (reported as €22M / £19.2M) - Total funding to date: ~$40M ### Investor Profile HV Capital and Northzone co-led the round, with Prudence, Mercia, MMC Ventures, and AFG joining. Existing backers Speedinvest, Seedcamp, and Anthemis followed on. HV Capital brings European enterprise software depth, and Northzone has a track record in vertical AI bets across Europe. The mix of generalist and specialist funds matters here because Fifth Dimension is selling into a regulated, fiduciary-heavy buyer base where investor introductions to large asset managers carry real weight. ### Company and Leadership Fifth Dimension was founded in 2023 by Dr Jarvis and Johnny Morris. The company runs from London with satellite offices in New York and Singapore, mapped to where its institutional real-estate customers concentrate. The founding pair built the business around real-asset workflows from the start, rather than pivoting a general-purpose AI tool into the vertical. ### Problem and Opportunity Institutional real-estate and infrastructure investors run on fragmented data sitting across Yardi, Argus, Dealpath, SharePoint, and dozens of one-off models. Analysts spend weeks pulling that data together for deal screening, IC memos, and lease abstraction. Underwriting a single deal can take two weeks. The pain point is acute for asset managers running large portfolios who can’t add headcount fast enough to keep pace with deal flow. Global real-estate AUM sits near $13T and infrastructure AUM north of $1.3T, so even modest workflow gains translate into meaningful capital deployment. ### Product and Technology The flagship product is an agent called Ellie that handles deal screening, IC memo drafting, portfolio variance monitoring, and risk surfacing. Fifth Dimension claims customers screen 4,000+ deals versus 2,000 prior, generate board decks in 2 hours instead of 40, and cut underwriting from two weeks to one day. The system runs on 50+ orchestrated AI models trained on real-estate and real-asset workflows. It integrates with Yardi, Argus, Dealpath, and SharePoint, and supports on-prem deployment for clients who require it. Data isolation is strict: no cross-customer training, SOC 2 Type II, ISO 27001. ### Use of Proceeds and Vision Capital goes toward global scaling across London, NYC, and Singapore offices, deeper development of Ellie, and expansion into adjacent verticals like infrastructure, net lease, and opportunistic strategies. Engineering, AI research, and GTM teams are all growing. The vision is a decision intelligence layer for the trillion-dollar real-assets industry, with auditable reasoning chains that meet fiduciary standards. ### Market Context Reported customer outcomes include 5x more capital deployed with the same team, 5% NOI lift, 98% accuracy on financial modeling, and $30-50M annual cost elimination at a public REIT. Marquee customers include BXP, Realty Income, Peachtree Group, and Madison International Realty. Competition spans verticalized real-estate AI platforms like Cherre, Northspyre, Skyline AI, Enodo, HouseCanary, and Cred iQ, plus legacy systems Yardi, Argus, and Dealpath, and horizontal enterprise AI agents trying to move down into the vertical. ## 2. Gizmo Raises $22M For AI-Native Learning ### Deal Overview - Stage: Series A - Sector: AI / Consumer EdTech - Geography: London, UK - Round size: $22M - Prior funding: $3.5M seed led by NFX ### Investor Profile Shine Capital led, with LocalGlobe, Ada Ventures, Seek Investments, GSV, and existing backer NFX participating. GSV brings deep edtech distribution and conference reach, while LocalGlobe is one of the more active UK consumer investors. The presence of both consumer-focused and edtech-specialist funds reflects Gizmo’s positioning as a TikTok-native study app rather than a traditional learning platform. ### Company and Leadership [Gizmo](https://gizmo.ai) was founded in 2021 by Petros Christodoulou (CEO), Robin Jack, and Paul Evangelou. The team is scaling from roughly 7 pre-funding to around 30 with this round. ### Problem and Opportunity Students spend hours on TikTok and Instagram while academic performance declines across most developed markets. Traditional study tools like Quizlet and Anki haven’t kept pace with how Gen-Z actually consumes content. The opportunity is making study habits as sticky as social feeds. Gizmo has grown from 300K users in 2023 to 13M+ across 120+ countries, which gives a clear read on demand. ### Product and Technology Gizmo converts notes, PDFs, YouTube videos, PowerPoint files, and Quizlet sets into bite-sized quizzes and flashcards using active recall and spaced repetition. Game mechanics include leaderboards, achievement streaks, daily lives that get consumed on wrong answers, friend challenges, and a competitive mode called Gizmo Live. The data flywheel comes from 13M+ users generating engagement, retention, and learning-outcome signal that feeds question generation and difficulty calibration. Communities on TikTok, Instagram, and Discord drive organic growth at low CAC. ### Use of Proceeds and Vision The capital funds engineering and AI hires, US college market expansion (the next user segment beyond GCSE, A-Level, and AP), and product expansion into more content formats and deeper AI tutoring. The pitch is a Duolingo for studying that counter-programs declining academic performance and non-productive screen time. ### Market Context Global EdTech sits above $300B with consumer study apps a multi-billion-dollar sub-segment growing post-ChatGPT. Direct competition includes Quizlet (60M+ MAU), Knowt (7M users), Anki, Yuno, Nibble, and AI-native tools like StudyFetch, Unstuck, Photomath, and Brainly. ## 3. Adfin Raises $18M For Agentic Revenue Collection ### Deal Overview - Stage: Series A - Sector: Fintech / SMB Payments - Geography: London, UK - Round size: $18M (€15.3M) - Total raised: ~$30M in under two years ### Investor Profile Index Ventures led, with Visionaries Club, Stéphane Kurgan, and Andrey Khusid (Miro founder) participating. Index has deep European fintech experience, and Khusid’s involvement signals operator conviction in the agentic-software thesis. ### Company and Leadership [Adfin](https://adfin.com) was founded in 2024 by Tom Pope (ex-Stripe and Tink) and Ciprian Diaconasu. The team’s payments pedigree from Stripe and Tink gives them privileged knowledge of payment rails and regulatory plumbing across the UK and EU. ### Problem and Opportunity UK SMBs are owed £30B+ in overdue invoices at any time, and globally late payments exceed $3T. Accounting firms, law firms, and SMBs in professional services, trades, and care spend hours chasing customers through fragmented tools that either chase or collect but rarely both. Cash flow stress at SMBs has gotten worse in the current rate environment, so the buyer urgency is real. ### Product and Technology Adfin runs an agentic accounts-receivable platform with three modules: Capture imports invoices from accounting systems, Control runs AI-driven credit control deciding when and how to chase customers via email, WhatsApp, and SMS, and Collect handles multi-rail payment acceptance across direct debits, cards, wallets, and bank transfers with automated retry and configurable late fees. Native integrations with Xero, QuickBooks, Engager.app, and Socket plug it into the SMB accounting stack. Customers report being paid up to 7x faster than the UK average. The proprietary dataset of payer behavior across 1,500+ UK SMBs feeds the credit-control models. ### Use of Proceeds and Vision Funds expand the product into end-to-end cashflow management beyond receivables, into payables and forecasting. Engineering and sales hiring accelerates, and international expansion beyond the UK is on the roadmap. Adfin frames itself as the agentic money-movement platform for businesses, replacing fragmented invoicing, credit control, and payment tools with one AI-driven system. ### Market Context Competitors include Chaser, Satago, Upflow, Two, GoCardless, and Stripe Invoicing, plus accounting-bundled tools like Xero Pay and QuickBooks Payments. Adfin’s differentiation is combining AI-driven credit control with built-in multi-rail collection rather than offering one or the other. Tailwinds include agentic AI in finance, UK and EU open banking expansion, and SMB cash-flow stress. ## Lessons For Founders - Vertical AI is winning Series A capital in London. Fifth Dimension trains models on real-estate workflows, Adfin trains on SMB payer behavior, and both raised faster than horizontal alternatives would have. - Distribution data beats model novelty. Gizmo’s 13M users and Adfin’s 1,500 customers fed Series A theses more than any architectural claim did. - Founder-market fit shows up in cap tables. Adfin’s Stripe and Tink alumni pulled in Index plus the Miro founder; Fifth Dimension’s real-assets focus drew specialist real-estate angels and follow-on from Speedinvest and Anthemis. - Agentic framing is now table stakes. All three rounds were pitched around AI agents handling work humans used to do, not AI assistants helping humans work faster. - UK Series A still needs a global story. Each of these companies already has US or international expansion as the primary use of proceeds. London is the base, not the ceiling.
