Iskra is the finance AI that never guesses a number. Ask in plain English; a typed, deterministic tool reads the figure straight from your ledger, and every answer carries a receipt: the tools it called, the exact rows behind each number, and a spreadsheet you can download and hand to an auditor.
The rest of the category is racing to point a reasoning model at your books and let it think out loud. That is a great way to draft an email and a dangerous way to run finance. Three reasons it breaks down the moment a number has to be right.
Not reproducible
A reasoning model is probabilistic. Ask for your gross margin twice and you can get two answers. Finance needs one number you can stand behind.
Can fabricate
A model that generates numbers can generate a wrong one that reads perfectly. In accounting, a plausible hallucination is worse than no answer.
No audit trail
When your board or your auditor asks how you got a figure, “the AI reasoned about it” is not an answer. You need the working, on demand.
60
Every number Iskra reports comes from one of these. Each tool is a typed spec: named parameters, enforced rules, reads scoped to your org. The database computes; the model never does arithmetic. A reasoning model is the same black box no matter how much you invest. Tools compound.
The database does the math
Every figure comes from a typed query, not the model. It kills the class of counting and aggregation errors LLMs make.
Reported verbatim
Pre-computed values (Rule of 40, runway, margins) are quoted exactly as the engine returns them, never re-derived.
Org-scoped
Each tool reads only your organization's live data. Scope can't widen beyond what was asked.
Traceable
Answers carry a frozen workpaper of the rows behind each number, with a live drill-down into the source view.

The full catalog, with every parameter and enforced rule, is in the app.
Open any answer and Iskra shows its work: the exact tools it called, the calculation with the real values plugged in, and the source rows behind each figure with a live drill-down into the underlying view.
Then download it. The workbook is a real spreadsheet with live-recalculating formulas and one tab per source dataset, ready for an internal review or an external audit. A fidelity guard runs on every answer and flags any figure that did not come from a tool, so nothing is invented.

Boards, auditors, and investors do not accept “trust the model.” They accept a number they can trace to a source and reproduce on demand. Iskra is the finance AI built to clear that bar, so the answer you send to your board is the same one you can defend in a diligence room.
