If look at all the products you like that are already out there, probably few are first of their kind. E.g. React was proceeded (and followed) by numerous JavaScript frameworks. It’s totally fine (perhaps preferable) to improve on an existing idea — build a better mouse trap. What products annoy you? That could be an indication a product isn’t really fulfilling your needs. Are there any software products/services you want that are too complicated and expensive? Maybe build something easier, cheaper, and more niche. If you’re still at a total loss, you might consider partnering with an expert in some area that has a problem you can solve.
