Im new this this space and need abit of help!

Hey everyone. im very new to this side of the web and im not really a developer but more of a vibe coder i suppose. i was wondering if anyone had some advice on maybe how to promote a new start up company. I havent had much success lately. i tried reddit and had that blow up in my face. Hoping there might be some people who have just been through something like this. Thanks Dylan
