Just some tidbits I know about Fab...
They focus on being a "discovery engine" instead of a catalog style commerce site, and they've developed a platform for early stage designers/entrepreneurs to promote their own products.
90% of the products on Fab can't be found on Amazon.
They get between 30-40% of their traffic from mobile.
They did ~$150MM last year, and ~25% of that was from outside the US.
Not your typical drop-ship setup.
I have actually came across YANKO DESIGN, who run CKIE who seem to be trying to do something SOMEWHAT similar (yet entirely different...) But Yanko is actually trying to recruit designers (furniture and other stuff) - Which brings me to wonder that perhaps that was how FAB got started?
You say: "they've developed a platform for early stage designers/entrepreneurs to promote their own products."
I am kinda curious as to how you get your products promoted (I do make SOME furniture... so I am curious about this)
I know YANKO actually also PROMOTE designers and whatnot as their main goal on site and here is what they say on CKIE about this:
"
[h=1]Sell Your Design[/h] If you're an artist with great designs to sell on the CKIE Store by Yanko Design, we want to hear about it!
Yanko Design has a growing audience of over 1.8 million+ unique visitors, making 6 million page views each month. It is the world's most popular and influential online design magazine."
...So what if FAB.com is really just an affiliate of many designers and linking everyone searching their site, with the actual designers and actually have absolutely no inventory, just like a dropshipper? I know I am sounding like I am saying the same thing but I think it is the approach that is different, just like Yanko.
I swear, it makes a whole lot more sense in my head than how I wrote it hahaha.
