Show HN: Quantus – LeetCode for Financial Modeling

Hi everyone,

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.

Thank you!

Great interface. I love the fact we can use Google Sheet to do the math.

That's an excellent query! Many have asked for a mobile app. Right now, we're improving the desktop version as Excel works best on it. Making Excel easy to use on a mobile app isn't easy. Our plan is to first make a mobile app centered around finance quizzes and concepts. Then, we'll aim to provide a complete Excel experience for financial modeling on mobile.

The mobile spreadsheet problem is definitely a hurdle, I think finance quizzes would be great to have on the go as a supplemental education piece.

Breaking down the formulas that work in certain situations or how certain modeling strategies are implemented conceptually could also lend well to a mobile platform without also requiring a “mobile spreadsheet” approach, which in all honesty sounds like a nightmare development process.

Either way, love the platform and wishing you all the best!
