Finny is Strategoo's flagship SaaS: it takes Belgian founders from idea to a bank-ready, legally compliant financial plan. A conversational AI intake captures the business model, a deterministic computation engine produces the financial plan with Belgian fiscality built in, and accountancy firms run client dossiers in their own branding, with an AI critic reviewing every plan before it goes out.
Challenges & Solutions
Legally defensible numbers, not plausible ones
A financial plan for a company incorporation must survive a notary, a bank and, in the worst case, a court. Belgian specifics like VAT regimes, legal-form rules, depreciation and opening balances from real bookkeeping leave no room for AI guesswork.
A deterministic engine with AI kept at the edges
We mapped the official Belgian financial-plan template field by field into a typed computation engine. AI conducts the intake and writes the prose, the numbers stay deterministic. An AI critic combined with hard rule checks, real cash, capital adequacy, reviews every plan.
Accountancy firms need their own standards, not ours
Firms want plans in their house style, with their templates and their review workflow, plus a safe way to invite clients into the intake without exposing other dossiers.
Multi-tenant workspaces with firm branding
Firms manage client dossiers in their own workspace, send intake links, collaborate with section locks, and export PDF plans carrying their logo, billed through credit-based pricing that matches how firms actually work.
01. Reference Model
We started from the official Belgian financial-plan structure and dissected real notary-grade plans to define exactly what a compliant plan must contain.
02. Computation Engine
We built and test-covered the deterministic engine, P&L, balance sheet and month-by-month cash flow that hold up to expert review.
03. AI Intake & Critic
We added the conversational intake with document upload, and an AI critic with deterministic rule checks and its own evaluation harness.
04. Scale to Firms
Multi-tenant organisations, firm branding on exports, bookkeeping imports and credit billing turned Finny into a platform accountancy firms run as their own.
A statutory financial plan used to be days of expert spreadsheet work. Finny turns it into a guided conversation, with numbers that hold up at the notary and the bank.
