There is also Kagi
Also there is no actual path for them to be profitable (their pricing strategy isn’t viable imo) and they are currently loosing money on every search.
It's not _just_ that: https://kagi.com/faq#Where-are-your-results-coming-from
Anyways, Kagi results vastly outperform Google results in quality for me. I'd happily pay the rather steep price they are currently targeting, should that end up being how expensive it is.
We have a path to profitability. Indeed, the entire business model is engineered to be sustainable. Whether the price will be accepted by the market (we do not need many users to be profitable, maybe around 50,000) is another matter. I am sorry if you do not feel like on. But one thing we will not do, is loose money on every search.
You have a theoretical path to profitability, but as you haven’t yet charged a penny it’s not proven to be viable. I genuinely hope you prove me wrong, and turn on paid subscriptions and it’s a huge success. If it’s not, better to learn that lesson now while you still have a chance to change course.
