I love the notion. The marketing "better than DDG" is a little janky. Perhaps consider a positive statement, like "finally find what you're looking for".
This is a crowded landscape. I've been here since Gopher and seen plenty of services come and go. With that in mind, here are some questions you might want to consider:
How does it compare with products like SearXNG, specifically their ecosystem of plug-in search types?
How do you plan to pay for it?
How do you expect to protect the index against spam?
