How would you draw the MarketPlace Logo?

Using the Mould Tool (as Gary suggested), you can get quite a decent result.

But, how do you go about separating all the individual squares?

I tried: Convert to Editable Shapes, then Ungroup. But, that doesn't separate all the squares.
However, you can CTRL+Click to select individual squares. Not ideal, but it does work.
