Every year I reflect on how I spent money in the previous year. Previously, I have manually scraped my bank statements and put together a report, but 2025 was interesting because I built a fairly overkill personal finance product to make this report easy to generate for myself.

Because it is really easy, I m going to do a deep dive on how I spent money in 2025. (I was able to put this all together in ~10 mins)

I'm building My Financ , which is a tool that allows you to understand your finances, and plan for the future.

I launched on PH in September, got some users and have been iterating.

I have been (slowly) building My Financ . I shipped some features over the past few months that felt interesting to share, so I build a sandbox that runs an almost-fully-featured version of the app (here) with dummy data. you can go in there, click around, and see what the feature set looks like:

is this confusing? on intuition i feel like people hate guided product 'tours' so have strayed away from this, but maybe it isn't clear the steps you would have to take as a user to actually get the app into this state?
any feedback welcome :) I realize that for a situation where you are linking your bank accounts to a website the polish and trust needs to meet a pretty high bar, so the main goal of this effort was to make it easier for a user to understand whats behind the onboarding.

I'm learning (slowly) about the importance of marketing your product. (I am probably one of todays 10,000 around guerrilla marketing)
So last night I hacked together https://purposefulpoop.com/ to see if it could drive some leads for my product.
I'm going to launch the playful tool next monday and use this thread to give a plot synopsis on how it all goes.

Prior to launch though, I'm curious if anyone has any feedback that might make the hook stronger?
I added (a poorly designed) OG image, so the shareable is at least somewhat tasteful:

What else am I missing?

First off, I'm looking to get a cohort of beta testers for the next development cycle! No cost to use the product, just would be curious about your feedback. If you are in this cohort I would give you 6months free once I actually launch. Feel free to post up below and I can give you more info, or contact me.
I added 2FA! Pretty self-explanatory, but adding 2FA for added security.

I added a new accounts view. This is the precursor of the soon to come "account overview".

I originally asked if guerrilla marketing works in another thread. Here are the results from my first experiment with this style of marketing!
On 3/31 I launched a quick and dirty (pun intended) tool:

With the hope that the CTA at the bottom of the page might drive some traffic to the personal finance tool i'm (constantly talking about) building.
So what happened?

TL;DR:
Nearly 2,000 people visited my meme
A little over 300 people clicked the CTA
A little over 20 people made accounts
Marketing like this feels useful! and I will continue to try things like this in the future!

There have been a few threads in the past week or so asking for roasts:

Now, what are some things you've built or marketing ideas you've ran with that you are proud of?
Ya ya you grew your b2b compliance saas to 1m MRR, but what I really want to know is there a button on the page somewhere that you are super psyched about? did you go viral and see a thicc spike in your google search console traffic with some witty tweet?
I have no thicc traffic numbers to be jazzed about yet, but when working on My Financ I spent a ton of time making a recursive grouping function and table for transactions. it allows you to slice up your spending in tons of ways, (I made it extensible so I could in theory allow users to define their own custom grouping functions as well!)

The constraints you set here ^ are reflected in the table of the transactions you would see here:
