Like the most interesting man in the world might say: we don't always design logos, but when we do, they're pretty awesome.
We design almost exclusively using Sketch which produces a "vector" image. The benefit of this style of image is that you can shrink or enlarge it without any image corruption. If you look at most companies logos, you'll notice they look worse the bigger they get. Whenever you take over the world, we want to make sure that you can print a flag with your logo on it as big as you please.
