Simple, fast and accurate. Deal analysis you can trust, every time.
I spent six years in investment banking, regularly working 60+ hour weeks. Fifteen to twenty of those hours went into Excel.
Most of that time, over 60%, wasn't spent building models from scratch. It went into the work that came after:
- Preparing scenarios and stress tests for investment committees
- Updating models minutes before a client or internal meeting
- Picking up a colleague's model while they were away
- Getting up to speed on a third-party model that landed at 7pm, for a meeting the next morning
The hours were only part of the problem. Constant time pressure raises the risk of errors, and most of this work was hard to automate. So the long hours were simply accepted as a rite of passage.
AI is changing that. It's already excellent at writing formulas, scaffolding models and speeding up analysis. But in high-stakes financial work, speed isn't enough. The output has to be predictable, traceable and accurate.
That's the bet behind Fontics: speed, accuracy and simplicity will stay valuable in Excel, however capable AI becomes.
The problem
AI builds the model. Someone still has to trust it.
Modelling time splits roughly in half. Building is one half, and AI now does most of it. The other half is validating and analyzing the result, and that's where the hours and the risk still sit.
- Build · 50%
Formulas, model builds, data analysis. AI can handle up to 90% of this. - Validate · 20%
Sense-checking assumptions and auditing the model. Fontics can handle up to 90% of this. - Analyze · 30%
Deal structuring, scenarios, sensitivities and stress tests. Fontics can handle up to 90% of this.
Use AI to build and Fontics to validate and analyze, and you can cut up to 90% of modelling time.
The solution
Deterministic analysis, inside the models you already use
Fontics is AI-free by design. Every calculation is deterministic, built on Excel formulas, and runs directly in your existing workbook, so the answer is the same every time and you can trace exactly where it came from.
With Fontics you can…
- ✓Map the drivers of any deal in seconds
- ✓Run 10 scenarios on any model in seconds
- ✓Stress test any model in seconds
- ✓Refine complex deal structures in minutes
- ✓Audit a 50-sheet model in minutes
- ✓Run Monte Carlo on any model in minutes
The goal is simple: get to the right answer quickly, and know you can trust it every time.
Example: driver analysis
Map every driver of a deal and see how far each one moves the output up or down. In this case, the output is IRR. Fontics then runs a sensitivity on each driver, so you can see at a glance which assumptions really matter.
In Excel: 30+ minutes. With Fontics: 2 minutes.
