It’s only dangerous to your determination, and work ethic. Because it can feel hard to continue an idea if there is already an implementation out there. Ordinarily though, to make money you will have to release the product, and competitors as well as customers will now know about you. If your entire implantation took a short time, then it will be easy enough to clone. To avoid cloning by a major company, you should pick an implementation that goes against one of their core user experience elements. For example, Slack began as a chat service for small working teams, and only small teams. Other chat services existed but they let you talk to anyone, or they were pure customer-service chat. Those competitors found it hard to integrate any ideas from Slack because doing so would essentially weaken their existing product.
