we're fourhundred studios
a design and development studio based in London.
we specialise in creative, 
psychology-backed products and tools across web and app.
our first launch 
"Ma – Clean Tabs, Clean Mind" is a tab manager with a difference
– revolving around the Japanese principle of "Ma"
(a pause, a gap, or negative space), the extension makes use
of a unique mental model to match our brain's natural way of offloading – allowing
you to offload your tabs simply, easily, and with peace of mind, whilst also freeing up memory on your laptop to let it run faster.
learn more and install the extension on the Chrome Web Store
we've got plenty more in the works,
so you'll be seeing more of us soon.
