Technical Architecture

How the platform is designed for reliability, auditability, and enterprise integration.

Layered Architecture

Layer 1

Presentation Layer

Web-based interface for model building, input management, and result visualization.

Layer 2

Logic Layer

Core calculation engine that processes models. Deterministic, testable, and auditable.

Design Principles

Separation of Concerns

Each layer has a single responsibility. Changes in one layer don't cascade unexpectedly to others.

Auditability

Every calculation can be traced. Every change is logged. Every decision has a history.

Data Integrity

Structured data models prevent the ambiguity and errors common in spreadsheets.

Deterministic Calculations

Given the same inputs and model, you always get the same outputs. Reproducible results.

AI Integration (Finny)

How artificial intelligence is integrated while maintaining control and auditability.

Context Building

Finny receives relevant context about your current model state, not your raw data.

Guided Responses

Responses are tailored to your role and the task at hand. CFOs see risk emphasis; analysts see detail.

Audit Integration

AI interactions are logged and can be reviewed. Nothing happens in a black box.

Data Boundaries

Your data is not used to train models. Finny works within your context, not on your data.
