What do you think Product Hunt is missing? What would you improve?

I absolutely love this platform.

The fact that I spend time here every single day is probably proof enough.

PostureGuard - Your quiet posture coach, running locally

PostureGuard monitors your posture in real time using your webcam, but everything stays on your machine. No accounts, no recordings, no cloud processing, just a short calibration, silent background monitoring, and native OS notifications when you start slouching. Built with Python + MediaPipe and fully open source.

Build your brand before your product, or launch first and reveal yourself later?

  1. I've always been on the personal brand side. More and more founders are building it now (sometimes even before the product is ready while it's still in development, before seed fundraising). The CEO builds their position so the product sells more easily at the official launch.

  2. But I have experience with people who built the product, scaled it, and only then did we discover who was behind it.

Honestly, with the first approach, I'd be concerned that people invest more in me as a person than in the product. People would idealise the founder and overlook the product's flaws (which could hurt development and constructive feedback).

+ I noticed the most common mistake that many people who started building a personal brand first, connected their product to their personal accounts (emails, social media, etc.) and started having a problem selling these things, because they cannot "give someone keys" to their personal profiles.
