Interesting idea, but I haven't found a compelling reason that phi is inherently superior, aesthetically speaking. Seems more like a marketing spiel.

That said, it still looks good.

I tried to find pricing for it (the top "contact sales" is a no-starter; too much initial friction. Just tell me how much it costs?! At the footer is a pricing calculator... I asked for pricing for 10 top-level pages and 5 sub-level pages (they explain the difference)... came out to a whopping $16,500 (you're reading that right... SIXTEEN THOUSAND). No thanks.

While the golden ratio thing is a bit of a gimmick, the components look gorgeous and really well laid out

I thought this was an unhinged parody of a design site, kinda surprised it's a real thing. Unfortunately the design isn't for me, things look off center and the overall "weight" of components feels off.
