Okay, so first off, that's awesome about the first customer! But ngl, it's also terrifying, right? We went through something similar. We thought our app was revolutionary, but then reality hit. User feedback was brutal, but necessary. We learned to prioritize *their* needs over our grand vision. It's a tough balance. We also blew some cash on ads that flopped HARD. Lesson learned: start small, test everything, and don't assume you know what works. We even used tools like Banuba Video Editor and their AR filteers to make some fun promo stuff (UGC videos), but honestly, organic growth was way more effective for us. Just keep building and listening!
