I have a list of 50 people that I would kill to have a coffee with. Niche founders, retired experts, brilliant writers.

But the reality is: They won't read my cold email. And honestly, they shouldn't have to. They are busy.

The 10% Problem
I realized that for all the crawling Google and OpenAI do, they have only captured maybe 10% of human intelligence. The other 90% the "Dark Matter" of wisdom is still locked inside people's heads, private journals, or offline experiences. It is "gatekept" by time and physics.

Three days ago, I hit "Publish" on Product Hunt for ExtraBar, a menu bar customization tool I'd been building for months.

I honestly didn't know what to expect.

What happened next caught me completely off guard.

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)

Dear Product Hunt community,

If you re reading this and you ve launched something - or you're close to launching - you are already incredibly special.
