After 9 months of work, I’m excited to share a major update to Quantus Finance, a platform for learning and practicing financial modeling. Traditional training often involves downloading Excel files, reading long PDFs, or watching videos that rarely match the Excel file. It hasn’t changed in 20 years.

I built Quantus to make practicing financial modeling easier. It has an Excel-like interface where users can solve problems directly in the browser — from beginner to advanced — with hints, formula explanations, and instant cell-by-cell feedback (think LeetCode for financial modeling).

The platform now includes 20 practices, covering 3-statement models, DCF, LBO, and M&A. I’ve also added keyboard navigation and sensitivity analysis.

Quantus is designed for career switchers and professionals who want to prep for interviews, build projects, or sharpen skills for work.

Here’s a demo video of an LBO practice in action. https://youtu.be/J4LFDb1heOw

I’ve incorporated a lot of feedback from the last launch and would love your thoughts!

- Agree with you on adding more challenging quizzes!

- Having the various mini assignments in a module on the same tab is an interesting idea.

- Regarding the bird lol, yea, I do plan to redesign the UI at some point to make it more professional look

- We are adding a few more LBO cases

- Sensitive table is a good idea

- Regarding your suggestion on auto-pulling finance data to build dynamic exercise, that is something I have been thinking about from the beginning.

- Double entry accounting is interesting! actually I have been considering building training materials to the offshore accounting firms.

Thank you so very much taking time playing around the tool and writing these thoughtful feedback! Really appreciate it!!

1. The large portion of finance is customization. AI works on the simple models, but it may struggle to perform adequately with complex, company-specific situations. Take pilot as example, it is an accounting and bookkeeping company with the combination of tech solution and human services. There is always human in the loop.

2. Finance deals with the numbers, the bar of accuracy is very high.

However, I believe AI can make learning finance much simpler, that is why I build this platform.

For beginners, it is a good tool to understand the basic finance and accounting concepts. It is interactive, you can practice the formulas via quizzes, much more fun than reading a textbook. I suggest you try financial statement module.

For intermediate users, you can practice financial modeling by solving generic modeling problems (3-statements, DCF, LBO, M&A). It will help you build the muscle memory of using the functions/formulas.

For advanced users, I am planning to onboard more industry specific modeling content and practice cases.

The best way of learning financial modeling is by doing it on the excel. Even though many finance technical interviews still focus on behavior type of questions, discussing your model-building approach and assumptions. By practising different scenarios on Excel, timeboxing it, it will help you refine your responses during the interview.

I wanted to share Quantus, a finance learning and practice platform I’m building out of my own frustration with traditional resources.

As a dual major in engineering and finance who started my career at a hedge fund, I found it challenging to develop hands-on financial modeling skills using existing tools. Platforms like Coursera, Udemy, Corporate Finance Institute (CFI), and Wall Street Prep (WSP) primarily rely on video-based tutorials. While informative, these formats often lack the dynamic, interactive, and repetitive practice necessary to build real expertise.

For example, the learning process often involves:

- Replaying videos multiple times to grasp key concepts.

- Constantly switching between tutorials and Excel files.

- Dealing with occasional discrepancies between tutorial numbers and the provided Excel materials.

To solve these problems, I created Quantus—an interactive platform where users can learn finance by trying out formulas or building financial models directly in an Excel-like environment. Inspired by LeetCode, the content is organized into three levels—easy, medium, and hard—making it accessible for beginners while still challenging for advanced users.

Our growing library of examples includes:

- 3-statement financial models

- Discounted Cash Flow (DCF) analysis

- Leveraged Buyouts (LBO)

- Mergers and Acquisitions (M&A)

Here’s a demo video to showcase the platform in action. https://www.youtube.com/watch?v=bDRNHgBERLQ

I’d love to hear your thoughts and feedback! Let me know what other features or examples you’d find useful.

  > First, you have to get clear on what the company is looking to get out of the project. 

You need to be able to sense the company direction, communicate clearly, manage the risk, build the trust. This is not an easy task in a big company.

Such an awesome article IMO that explains the art of shipping in a big firm. I believe if any engs can master the skills described in the article, you will get promoted to a leadership role very fast. Of course, this might not be the path everyone loves.

If you do the math, climbing the corporate ladder at FAANG might have better ROI than running life style business. Of course, money is not the only consideration in life.
