Vibe Coding for CFOs (bring a prototype in a meeting)
The simplest way for CFOs to experiment with real AI, fast.
CFOs talk a lot about AI.
But most end up with dumb apps like:
Simulators.
Static workflows.
Dashboards that look modern, but don’t think.
We’ve been using AI to code tools that do exactly what we tell them.
Nothing more.
But that changes today.
CFOs must experiment with a new type of AI development using Google AI Studio.
These apps are different. They’re pre-wired with Gemini (AI) out of the box. Which means you’re not just building with AI. You’re building AI into the app itself.
Imagine a variance commentary tool that not only organizes numbers but also asks you for clarification, suggests what to highlight, and rewrites your narrative to sound on-brand.
That’s what today’s letter is about.
You’ll understand when Vibe Coding works and how to vibe code real AI apps for finance.
You’ll build Finance Narrative Generator
And AP Optimizer
You can copy-paste the prompt into Google AI Studio, it’s free.
Involve your finance team.
Skip the hackathon. Just do this:
Before the meeting: everyone builds a tiny AI app (30 min max) for a real pain point. No real data. One sentence: “This replaces [manual thing].”
During the meeting: 3-minute demos. Team votes on what’s worth building further.
Let’s dive in.
When Vibe Coding Works in Finance
Start with a micro-problem.
Use AI to vibe-code an actual prototype.
Skip the hackathon. Just tell your team:
“Show up to the next meeting with your own AI app.”
That’s it.
Google AI Studio makes this incredibly easy.
In 30–45 minutes, anyone on the team can:
Describe a workflow (e.g. “generate monthly close status based on checklists”)
Get a working React app wired to Gemini.
Share a link that does something smart, not static.
Most AI apps aren’t actually smart. They’re just coded quickly.
Smart AI apps:
Ask questions back.
Generate variants.
Give suggestions, not just answers.
Create a two-way loop, not just outputs.
The real innovation here isn’t the tech.
It’s the creative process.
AI makes it so easy now that you don’t need multi-team hackathons.
You just need a workflow idea and 30 minutes.
Building Finance Narrative Generator
You can upload this file. And get a variance analysis screen shown above.
You can generate analysis.
This app talks to Gemini and writes a first analysis.
At the bottom of the analysis, AI asks some questions to better understand the variances.
And AI generates a new narrative with the user input.
