What design challenges are you facing in your product?

Marketing, sales... it's all well and good, but primarily, startup products are subscription-based. If we want long-term customers, they must enjoy the experience of interacting with the product and feel the desire to return. I've outlined a few possibilities, but I want to hear about your specific pain points. Your responses will help me, as the owner of a UX design studio, better understand the needs of potential clients—startup companies—and focus on key areas. If you haven't found your option in the list, please write it in the comments. 💬
