I'm working on a SaaS with limited budget actually I dont know what the budget even is the product is 80% ready and I havent spent a single dollar yet. I guess the whole product will be ready with $0 budget but then I'll have to spend some on getting a good domain and hosting. I use firebase rn as the product is not yet complete. But I am a builder I dont know anything about marketing and stuff. How do I get my first paying customer? Can you share how you guys did it? I have no clarity regarding...
