What it does

Your spreadsheet. Your process.
Pythia does the work.

Pythia works on the files and workflows your team already runs. Nothing to rebuild, nothing to migrate. It just takes on the parts that eat your week.

01

Work faster

Data pulled, models updated and calculations run for you, in the file you already use. The hours spent preparing the numbers come back to your team.

>50%Time back from manual processes
02

Analyse more

Pythia analyses every deal, cell and data point, not just the ones you have time to check. Patterns, changes and their impact surface on their own.

Pythia runs the process

On your schedule, Pythia gathers the data, chases context from the business, tests scenarios and briefs you on what matters. You focus on the decision.

How it works

Your workbook is already a graph.
Pythia maps it.

Pythia reads your whole workbook, cell by cell, formula by formula, and turns that structure into an ontology, so it can calculate deterministically on your model rather than guess at it.

Trust, governance and security

Numbers you can trust and defend.

Finance data is the foundation for every business decision. Accuracy, traceability and governance are critical.

We adapt to your model
No clean-up, no rebuild. Pythia works in your existing Excel and Google Sheets files, so the numbers stay where you can see them.
Numbers are deterministic
Pythia maps every formula and cell, then calculates with code, not an LLM. AI is used for insight and communication, never to guess a number.
Every change is traceable
What changed, where and why, traced back to the cell. Nothing is a black box.
Your data stays yours
An isolated environment for each customer. Your models never train foundation models.
Version history
Every change, comment and reviewer tracked, from the first draft to the version that went out.
Audit trail
Every Pythia action logged with its inputs, outputs and who acted on them.
Granular permissions
Control who can see, edit and approve each model.
