Foundations and
Definitions
The governing principles, operative definitions, company taxonomies, compliance framework, and maturity model that underpin all seven Books of the Standard.
Download Book 0 (PDF)Purpose and Scope
The FFI Standard applies to any company at pre-incorporation stage or later that is building, maintaining, or evaluating its financial infrastructure, regardless of legal entity type, jurisdiction, funding status, or company type. It does not prescribe how financial infrastructure is built or who delivers it. It defines what must exist, at what level of completeness, and by what stage.
The Standard does not constitute financial advice, legal advice, tax advice, or investment advice. Compliance does not guarantee investment outcomes, fundraising success, or financial solvency. The full limitation of liability is set out in the Disclaimer.
Versioning Policy
The Standard follows a three-tier versioning policy. Errata versions correct factual errors without altering any requirement. Minor versions update benchmarks and clarify requirements. Major versions make structural changes and are subject to independent advisory panel review from version 2.0 onward. The current version is Beta v0.5, published April 2026. Version 1.0 is expected by end of 2026.
Prior versions remain permanently accessible at the Version History page. An assessment completed against a specific version remains valid at that version.
Core Principles
Three principles govern the application of the Standard across all Books and all company types.
- Infrastructure, not deliverable. Financial infrastructure is a continuous function maintained at all times, not a set of documents assembled for a specific event such as a fundraise or board meeting.
- Stage-appropriate standards. The compliance requirements vary by stage. A company at Inception Stage is not held to the same standard as a company at Growth Stage. The maturity model in Section 0.8 defines what is required at each stage and level.
- Observational, not prescriptive. The Standard defines common deficiencies as observable conditions, not as judgements about management quality. A deficiency is a gap between what the Standard requires and what currently exists.
The FFI Glossary
The Standard defines 178 terms that carry operative meaning across all seven Books. Each term has a precise definition that governs its use throughout the Standard. Where common usage of a term differs from the Standard's definition, the Standard's definition takes precedence within the scope of this framework.
All 178 terms are available on the Glossary page, each with its operative definition, common misapplication, related terms, and citable URL. The five most foundational terms for navigating the Standard are:
- Financial Infrastructure — the complete system of models, processes, reporting, and documentation a company maintains
- Three-Statement Model — the dynamically integrated income statement, cash flow statement, and balance sheet
- Founder Financial Infrastructure — the category of financial infrastructure specific to early-stage companies
- Unit Economics — the direct financial metrics associated with a single commercial unit
- Cap Table (Fully Diluted) — the complete record of all equity ownership and equity-linked obligations
Company Stage Definitions
The Standard applies different minimum compliance requirements at each stage. Stage is determined by the company's revenue, team, and operational maturity, not solely by funding status.
Pre-revenue. The company is building its initial product and has not yet generated meaningful commercial revenue.
Early revenue or pre-revenue with an institutional investor. The company has received or is seeking a first external institutional investment.
Revenue generating. The company has demonstrated product-market fit evidence and is building repeatable commercial traction.
Scaling revenue. The company has established repeatable revenue and is investing to accelerate growth. Level 2 compliance is expected at this stage.
Institutional maturity. The company operates with full financial governance and is preparing for or has completed a Series B or equivalent.
Company Type Taxonomy
The Standard defines seven company types. Each type has a distinct financial infrastructure profile because the unit economics, revenue model, cost structure, and capital requirements differ materially between types. The compliance criteria in Books 2 through 6 include type-specific notes where requirements diverge.
| Company Type | Defining Financial Characteristic |
|---|---|
| B2B Enterprise | Long sales cycles, high contract values, pipeline-driven revenue, customer success dependency |
| B2C Consumer | High volume, low unit value, marketing-led acquisition, cohort retention as primary metric |
| AI-Native | Variable compute costs, usage-based pricing elements, rapid scaling economics, infrastructure cost concentration |
| Deep Tech and Hardware | Long development cycles, capital-intensive pre-revenue phase, milestone-based funding, manufacturing cost structure |
| Recurring Revenue | Annual recurring revenue as primary metric, net revenue retention as primary health indicator |
| Transactional Revenue | Volume-based economics, take rate or margin per transaction, GMV and net revenue distinction critical |
| Project Revenue | Engagement-based revenue, utilisation rate as primary efficiency metric, pipeline and backlog as forward indicators |
Company type subpages are available in the For Founders section, each covering the specific compliance notes and benchmarks applicable to that type.
The Compliance Framework
The Standard defines three compliance levels across all domains in Books 1 through 6. Compliance is assessed per domain, not as a single company-level score. A company may be at Level 2 in financial architecture and Level 1 in strategic financial planning simultaneously.
| Level | Descriptor | Investor Category | Governance Requirement |
|---|---|---|---|
| Level 1 | Structural foundations in place. Minimum viable financial infrastructure. | Angel, Pre-Seed | Founder-maintained |
| Level 2 | Full operational infrastructure. All domains maintained with institutional depth. | Seed, Series A | Board-reviewed monthly |
| Level 3 | Institutionally mature. Continuous readiness, departmental governance, strategic modeling. | Series B and above | Board-approved annually |
The Financial Infrastructure Maturity Model
The maturity model maps compliance requirements to company stage across the six operational Books. It is the primary tool for assessing where a company currently stands and what is required to progress.
| Domain | Inception | Pre-Seed | Seed | Growth | Scale |
|---|---|---|---|---|---|
| Financial Architecture | Pre-L1 | L1 | L1 to L2 | L2 | L3 |
| Performance Modeling | Pre-L1 | L1 | L1 to L2 | L2 | L3 |
| Capital Structure | L1 | L1 to L2 | L2 | L2 | L3 |
| Valuation | Pre-L1 | L1 | L1 | L2 | L3 |
| Investor Readiness | Pre-L1 | L1 | L1 to L2 | L2 | L3 |
| Strategic Planning | Pre-L1 | Pre-L1 | L1 | L2 | L3 |
