For me, and probably a lot of other people who moved from other search engines, long-term viability of Kagi is important - heck, that's the reason I've decided it's worth paying some money for search.
Given that, I'd expect them to be very frugal with their spendings. Burning money on T-shirts, on another Browser, AI "improvements", Kagi Email (wtf? first time I've heard of it) show that they have incredibly startupy mindset, and will end up like every other company that takes VC money - bloated, money focused and deaf to their community.
