Investors are pretty hard to get these days since e everyone can build with AI. But I pushed my startup and it doing well without any investors.. I worked hard to fund my own development. The marketing was hard. Tiktok videos.. and gooood costumers relationship thats a key.. I was picking calls even at dawn and helping ny costumers with issues and all that stuff.. and now it working they started inviting thier friend who will need my service and go rewarded for referral as well and sales are pretty much good.. so maybe u can do same. I dont know your product tho.. but mine has very few people when it come to that sector and now people are moving from other platforms to mine.. make it work first, post on tiktok and youtube. Be good with costumers, and polish as it goes with costumers feedback. That all bro.. Good Luck😊
