This is a common enough pattern that it should have a name, where the submitted link isn't clear, but a single comment on HN is.

The Cravens Conjecture

It is right there on the landing page. But, let me highlight it a bit.

When I ctrl+F the landing page for key and value, I find nothing. Reading it in full, I also come up empty handed. Which part of the landing page implies it's a key value store?

They did not say anything about key/value in their message.

You are absolutely right, my bad.

IMO, replace "More than a Cache. Smarter than a Database." with an actual description.

The saying is cute but does not really convey information the reader is after. And that spot is where you want people to immediately understand what it is.

I changed that :) now the value proposition is right at the top.

Still not clear to me what it is. Only the features it has, without knowing what it is.

Like, imagine a page that only said "SuperTransport -- 0 to 100 in 5 seconds", but it is not clear for the reader if it is a car or a horse or a plane or a parcel service...

... and the reader has to go and guess "hmm, guess due to the acceleration it is probably a car or a motorbike -- wonder of it is for sale or for rent?".

Just put "fast on premise key/value database" in the big font that was there -- if that is what it is. That is purely a guess from me, no idea if that is what it is.
