How to raise seed funding for web 3 start up?

Hey there, i am exploring entrepreneurship and trying to startup on a idea which I have pre-planned so now I want to really harness the power of web3 , defi and crypto to raise funds and make a good brand out of it. But i am really unaware of how can I raise seed funds since right now i am at idea stage with my startup therefore i would like to know from reddit how can I do it ? I would appreciate brief description. Thank you
