I spent 6+ years in investment banking, often working 60+ hour weeks.

Looking back, I spent roughly 15-20 hours each week in Excel as an analyst/associate. Much of that time, over 60%, wasn't building models from scratch. It was the work that came after:

• Preparing the scenarios or stress tests for investment committees
• Updating models minutes before a client or internal meeting
• Picking up a colleague’s model when they were away
• Ramping up on a third-party model received at 7pm for a meeting the next morning

The problem wasn't just the hours. Working under constant time pressure also increased the risk of errors. Yet much of this work remained difficult to automate. In investment banking, long hours were often treated as a rite of passage.

AI is changing that. It is already excellent at writing formulas, supporting models builds and accelerating analysis. But for many high-stakes financial workflows, speed alone isn't enough. The output also has to be predictable, traceable and correct.

That is the bet behind Fontics. I believe speed, accuracy and simplicity will remain valuable in Excel, regardless of how capable AI becomes.

Fontics was built as a deterministic alternative for the workflows where those qualities matter most. It helps you refine deal structures, map drivers, run scenarios, sensitivies, stress tests and model audits in minutes, directly inside the models you already use - releasing up to 10 hours of your time each week.

Sometimes it is faster than AI. Sometimes slower. Most times it is same speed. It has capabilities you cannot easily replicate with AI.

But the objective is clear: Get to the right answer quickly, and know you can trust it every time.
