Congrats on the mvp path you took to lunch your product. Generally, I think that there is a place for other variations of web search, be it in the way you crawl or perhaps how you monetize. I genuinely believe that it is really hard to build a general purpose search engine like DDG, Google and the like, but you can build a fairly good niche search engine. I'm particularly fond of the idea of community powered curation in search. Just today I lunched my own take on a community driven search engine - https://github.com/gkasev/chainguide. If you like to bounce ideas back and forth with somebody, I'll be very interested to talk to you.
