About this model
Fifth Dimension AI's Ellie SmartScript automates real-estate research reports, fact-checking, valuation drafts, summaries, and marketing content through an email-based interface. The product combines proprietary property data, vertical workflow tuning, brand-voice calibration, and a fact-checking process for real-estate professionals.
Customers buy company-level SaaS contracts, with 10 to 15 users per company and a £15,000 ACV used in the deck. Twelve weeks after launch, it had signed five paying customers; its milestone is 50 companies and more than £1 million ARR in 20 months.
The model uses a quarterly logo and ARR waterfall, testing contract value, seat expansion, churn, and referral-led sales. It ties LLM and hosting costs, engineering, marketing, and account-management hiring to the £2 million raise, monthly burn, and 18-month zero-revenue runway.
A turnkey financial model
Live formulas, no hardcoded values
Outputs are driven by live formulas, so the workbook updates from its assumptions instead of relying on hardcoded results.
All assumptions in one tab
Inputs are clearly marked in the Assumptions tab and separated from calculations, making it clear what to change and what to leave intact.
Statements always balancing
For integrated-statement models, the balance sheet, cash flow, and supporting schedules tie through properly.
Distinct schedules for clarity
Debt, working capital, taxes, and cash flow can get messy quickly. We group calculations in clear schedules, not across disconnected tabs.
No hidden macros or external links
There are no unexplained external workbook links or macros to undermine auditability or portability.
Changes flow through the model
Update a key driver and see the impact carry through the forecast, financing, and return outputs. We never use hardcoded numbers in formulas.

How to build a detailed financial model for Fifth Dimension AI
A complete walkthrough of the business, drivers, and assumptions behind the downloadable Fifth Dimension AI model - distilled from its pitch deck and publicly available information.
Product & value proposition
- MVP: AI tools branded "Ellie SmartScript" - email-based interface that automates research report writing, fact-checking, valuation report drafting, summarisation, and content production (social media, newsletters, presentations) for real estate professionals.
- Efficiency claim: "Boost efficiency by 30%".
- Key differentiators: proprietary real estate data (not open internet), vertical-specific workflow tuning, brand "sounds like you" tone calibration, fact-checking flow, Microsoft Stack plugin roadmap.
- Roadmap (slides 9): (1) multimodal inputs (brochures, images, charts, PPT); (2) Microsoft Teams/Word plugins; (3) Global Real Estate GPT (multilingual); (4) expansion to Finance and Construction verticals.
- Flywheel moat: de-identified aggregated user interaction data → structured prompt/response dataset → better models → higher customer ROI → more customers.
Market
- SAM: £16bn global real estate market - bottom-up: 1.1M medium and large real estate businesses × £15k ACV.
- Adjacent TAM (BI market): £24bn today → £43bn by 2030 (source: Fortune Business Insights, cited by company).
- Expansion TAMs cited:
- Finance: £114bn TAM
- Construction: £42bn TAM
- Global Real Estate SAM: £16bn
Revenue model
- Pricing: ACV of £15k per company used in SAM sizing. Customer persona notes "can spend £1,500pcm on SaaS without manager approval" (slide 6) - implying per-user or team-level monthly subscription.
- Units: B2B company-level contracts; 10–15 users per company.
- Channels: referrals and word-of-mouth (current); inbound sales pipeline.
- Interface: email-based (ellie@fifthdimension.ai) - low-friction adoption, no separate app install required.
- Revenue recognition: subscription ARR - monthly or annual; no invoicing/services revenue indicated.
Traction & metrics
- 12 weeks in: 5 paying customers signed.
- >30 in-depth customer research interviews conducted.
- Sales pipeline developed via referrals and word-of-mouth.
- Customer logos redacted in deck.
- Qualitative NPS proxy: "area description model 9/10" from a customer.
Unit economics
- ACV implied: £15k per company.
- Users per company: 10–15; implies blended per-seat pricing of £1k–£1.5k/user/year or a flat company license.
Competition / moat
- Moat strategy: proprietary vertical data flywheel - structured dataset of real estate workflow prompts/responses unavailable to open internet competitors.
- No explicit competitive landscape slide; indirect competitors implied: Tableau (mentioned as "dashboards in a drawer"), generic LLMs, and general-purpose AI writing tools.
- Differentiation levers: domain-specific fine-tuning, brand voice calibration ("sounds like you"), email-native interface, proprietary data accumulation.
Team & funding ask / use of funds
- Johnny Morris (Co-founder): 15+ years real estate data & analytics; prior roles at CBRE, Hamptons, Zoopla/Hometrack, Illustreets, Wayhome.
- Dr. Kate Jarvis (Co-founder): PhD Linguistics, Stanford; 4 CPO/CTO roles in past 10 years; prior: Wayhome, Shmoop, ST:NT, Careers & Enterprise Company.
- Funding ask: £2M, EIS eligible.
- Use of funds: engineers, marketing, account managers.
- Runway: 18 months assuming zero revenue (lean team).
- Target milestone: £1M+ ARR in 20 months = 50 companies onboarded at 10–15 users each.
Recommended financial model
- Archetype + why: SaaS ARR model with B2B logo/seat build-up. Revenue is annual contract value per company × logo count; the deck's milestone language ("50 companies", "£1M+ ARR in 20 months") maps exactly to a seats/logos ARR model. No marketplace, no usage-based billing, no inventory - pure subscription SaaS.
- Forecast horizon & granularity: Quarterly from today through 2025 Q1 (mirrors the deck's own cash burn chart), then annual through Year 3–4. Quarterly granularity is appropriate at this stage given the short runway and milestone-based targets.
- Key drivers & assumptions:
| Driver | Value | Source |
|---|---|---|
| ACV per company (£) | 15,000 | - |
| Users per company | 10–15 | - |
| Target logo count (20-month milestone) | 50 | - |
| Target ARR (20-month milestone) | £1,000,000+ | - |
| Raise amount | £2,000,000 | - |
| Runway (zero-revenue case) | 18 months | - |
| Monthly cash burn (implied, £2M / 18 months) | ~£111k/month | derived from deck figures |
| Starting logos | 5 | - |
| New logos/quarter ramp | ~4 in Q1 → ~10 by Q6–Q7 | Implied by needing 50 logos in ~7 quarters |
| Gross margin | 70–75% | Typical early-stage vertical SaaS; LLM API costs as primary COGS |
| Churn (annual logo) | 10–15% | Early-stage B2B SaaS benchmark |
| CAC | £5k–£10k per company | Word-of-mouth initial; sales-assisted later |
| Payback period | ~4–8 months | At £15k ACV and £5k–£10k CAC |
| Headcount build (use of funds) | Engineers + Marketing + AMs | ; split ~50% eng, 25% sales/mktg, 25% AM |
| Real estate SAM | £16bn | - |
| BI market today / 2030 | £24bn / £43bn | - |
- Scenarios (Base / Bull / Bear):
- Base: Hits 50 logos in 20 months at £15k ACV = £750k ARR by Q7 (ramp risk: not all logos signed on day 1). Gross burn ~£111k/month.
- Bull: Faster word-of-mouth; average ACV expands to £18k–£20k via seat upsell; 65 logos in 20 months → £1.2M ARR; runway extends via revenue offset.
- Bear: Logo ramp slower (25–30 companies in 20 months); ACV holds but revenue only £375k–£450k ARR; cash exhausted before milestone; bridge required.
- Flex variables: new logo ramp pace, ACV (seat expansion vs. flat), gross margin (LLM API cost trajectory), headcount spend rate.
- Required sheets / outputs:
- Assumptions - all drivers in one tab, toggle for scenarios.
- ARR Build - quarterly new logos, churned logos, net logos, ACV, new ARR, churned ARR, net new ARR, ending ARR.
- P&L - Revenue, COGS (LLM API + hosting), Gross Profit, Opex (R&D, S&M, G&A), EBITDA.
- Cash Flow / Runway - opening cash (£2M raise), monthly burn (headcount + non-HC), revenue receipts, ending cash balance; mirror the deck's "Cash Burn vs Revenue" area chart.
- Headcount Plan - role-level hire schedule tied to use-of-funds narrative.
- KPI Summary - ARR, MRR, logo count, NRR, CAC, LTV, LTV:CAC, gross margin, runway months.
- Market Sizing - TAM/SAM/SOM build, penetration curve through Year 5.

Created by ex-finance professionals
Hey, I’m Alex and I created Finamodel.
Over my years in the finance industry I kept building the same models over and over again. Same structure, same assumptions, different logo. So I started building frameworks to turn them into clean, reusable templates.
Every model here is one I’d actually use for a client, and I personally vet each one before it goes up.
I’m not an expert in every industry, but I’ve built enough models to know what belongs in one. And when something is completely foreign to me, I reach out to my network for experts to work on our models with us.
Having a template library on hand cuts a first build from hours to minutes.
Need help finding your model? You’ll find me in the Finamodel app!
