About this model

Griffin was founded in 2017 and became a fully authorised UK bank in March 2024. Its current website is griffin.com. Its company fact sheet, updated August 26, 2026, lists Series B funding and approximately $65M raised.

This downloadable model is a historical case study based on Griffin’s June 2020 pitch deck. References below to pre-revenue operations, seeking authorisation, planned lending, and launch milestones belong to that historical scenario.

The model explores banking economics: deposits, loan balances, asset yields, deposit costs, credit provisions, and fee income. Its projections are illustrative assumptions, not Griffin’s current financial results or guidance.

Historical model: June 2020. Company profile as of August 26, 2026: fully authorised UK bank since March 2024; Series B; approximately $65M raised. The historical model and its pre-authorisation assumptions describe June 2020, not current operations or financial results.

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 Griffin

A complete walkthrough of the business, drivers, and assumptions behind the downloadable Griffin model - distilled from its pitch deck and publicly available information.

Product & value proposition

  • Griffin is applying for a UK bank licence (FCA + PRA) to offer API-driven bank accounts with individually segregated customer sub-accounts and an integrated ledger.
  • Core pain point solved: fintechs and embedded-finance firms that are not banks must work with a partner bank for safeguarding/client money accounts, typically facing 3–6 months onboarding, pooled-account reconciliation complexity, and expensive DIY compliance infrastructure.
  • Griffin's offering eliminates reconciliation by pairing individually segregated accounts with an integrated ledger, and compresses time-to-market from 3–6 months to days/weeks via compliance-as-a-service.
  • Platform credits (£25–100K AWS/GCP/Azure-style) offered to early customers to drive lock-in.
  • Customers interact with Griffin via API and UI; nested end-customers interact only with the customer's own branded product.

Market

No quantified TAM/SAM/SOM figures in deck.

Addressable segments identified:

  • Regulated fintech: EMIs, Payment Institutions, CASS firms, brokerages, robo-advisors, FX/remittances, expense management, neobanks, P2P lenders, payroll cos.
  • Unregulated / embedded finance: gig economy, e-commerce marketplaces.
  • Strategic brands: prepaid cards, bank accounts, lines of credit (e.g. Google, Facebook, Mercedes-Benz cited as examples; disclaimer: no commercial agreements in place).

Market tailwind narrative: "every company is becoming a fintech company"; regtech unit economics have shifted; pro-competition regulators have lowered barriers for new banks.

Revenue model

Three revenue streams stated:

  1. Transaction and account fees - described as 70%+ of revenue at current interest rates.
  2. Net interest income from lending - secured lending to fintech customers against invoices/assets/receivables at ~12%; funded by term deposits at ~2%; NIM ~10pp. Rates rise with base rate.
  3. SaaS products (core banking, loan management systems) - positioned as a sales/pipeline tactic rather than a primary revenue driver.

Pricing detail: No specific fee schedules or per-transaction pricing disclosed in deck.

Customer acquisition channel: financial services register + Crunchbase for prospecting; AdWords, conferences, content marketing; partnerships with first-round funds, accelerators, regulatory/product consultants.

Traction & metrics

  • £1.8M remaining in bank from prior round (as of June 2020).
  • No customers, no revenue - pre-authorisation, pre-launch.
  • Tech progress: Kafka event-log architecture built; Kubernetes staging environment running; ledger and identity/document-verification API endpoints complete; UI framework in place (pending rebrand).
  • Exec team in place; two independent directors appointed; searching for 3 more.
  • Authorisation timeline slide (slide 18) is fully redacted - CONFIDENTIAL.

Unit economics

  • Stated assertion: "looks like a payments business; very high margin per customer."
  • Lending NIM: ~10pp (12% secured loan yield minus 2% deposit cost).
  • High fixed / very low variable cost structure asserted.
  • No CAC, LTV, payback period, or customer-level economics quantified in deck.

Competition / moat

Moats identified:

  • Bank licence itself: ~2 years to obtain, capital-intensive, requires scarce expertise - high barrier to entry.
  • Superior risk/compliance model: Griffin knows end-customers (nested accounts), unlike competing clearing banks which see only pooled accounts → better AML/financial-crime underwriting.
  • Switching costs: once a fintech builds on Griffin's API and integrated ledger, migration is expensive.
  • Data advantage: platform banking activity data used to underwrite lending.

Competitors not named directly. Indirect competition framed as "older clearing banks" offering pooled accounts with poor API experience (sometimes FTP file uploads).

Team & funding ask / use of funds

Team:

  • David (CEO) - co-founder; prior company Standard Treasury (2014–2015) sold to SVB.
  • Allen (CTO) - co-founder.
  • Rupert Whitten (COO) - former Head of Credit at a UK credit fund; COO through a UK narrow-bank authorisation; chaired investment committee for $65Bn portfolio.
  • Sam Perera (CFO) - former CFO of two UK banks (one through authorisation, one taken public); prior KPMG and PwC banking/audit practice.
  • Paul Virno (CRO) - former CRO of Paysafe; financial crime, operational risk, and finance roles across banking, asset management, and insurance.

Funding ask / use of funds: Not explicitly stated in deck. Deck is addressed to EQT Ventures (June 2020). Prior round left £1.8M in bank.

Recommended financial model

  • Archetype + why: Banking 3-statement model with balance-sheet-driven revenue (BaaS/neobank variant). Griffin's P&L is structurally a bank P&L: revenue = net interest income (NII) + non-interest income (transaction/account fees + SaaS). This requires modelling a balance sheet (deposit liabilities funding loan assets) to derive NII, plus a fee-income layer. A pure SaaS ARR or payments-volume model would be wrong - the lending book and deposit base are central.
  • Forecast horizon & granularity: Monthly for Years 1–2 (pre-revenue, burn/runway critical), quarterly for Years 3–5. Five-year horizon appropriate given ~2-year authorisation lag before revenue ramp.
  • Key drivers & assumptions:

*Customer funnel*

  • # B2B customers onboarded per quarter
  • Avg # nested end-accounts per B2B customer
  • Avg balance per nested account

*Fee income*

  • Monthly account fee per B2B customer
  • Transaction fee per payment (FPS/CHAPS/BACS/card)
  • Avg transactions per nested account per month
  • SaaS subscription per customer

*Lending book*

  • % of B2B customers that also borrow
  • Avg loan size per borrowing customer
  • Gross loan yield: 12%
  • Deposit cost: 2%
  • NIM: ~10%
  • Credit loss rate

*Revenue mix*

  • Transaction/account fees as % of total: 70%+; lending NIM makes up balance

*Cost structure*

  • Regulatory capital requirement
  • Headcount ramp
  • Technology / infrastructure (AWS, regtech, card scheme fees)
  • Platform credits given to customers: £25–100K per customer; treat as customer acquisition cost / deferred revenue contra

*Authorisation timeline*

  • Grant of Authorisation date
  • Scenarios (Base / Bull / Bear):
  • Variable 1: Customer acquisition pace (# B2B customers onboarded)
  • Variable 2: Average deposit/balance per nested account (drives NII)
  • Variable 3: Lending book build-out speed and credit losses
  • Variable 4: Authorisation timeline slip (Bear: +12 months of burn)
  • Variable 5: Interest rate environment (higher rates boost lending NIM; at near-zero rates fee income dominates as stated)
  • Required sheets / outputs:
  1. Assumptions (all drivers in one place)
  2. Customer model (B2B customers → nested accounts → balances)
  3. Income statement (NII + non-interest income − opex = PBT)
  4. Balance sheet (deposit liabilities, loan assets, equity/capital)
  5. Cash flow / runway (critical pre-authorisation; £1.8M cash burn clock)
  6. Regulatory capital (CET1, liquidity - simplified)
  7. Scenario / sensitivity toggle (auth delay, customer ramp, interest rates)
  8. Summary dashboard (revenue bridge, burn-to-breakeven, key ratios)

Alex Tapio, ex-Deloitte financial modelling expert

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!
