https://neeva.com/, but their selling point is slightly different (I don't really care about ads per se, or privacy, I just want to get good search results (without paid promoted results or weird interstitial results modals, looking at you "people also clicked on" Google box!) and maybe be able to do advanced queries (search by file type, date, booleans, etc. I would also like to be able to ban sites from my results, for example, all of the spammy websites that scrape stackoverflow and mirror the pages, which Google somehow hasn't blocked themselves yet...
