We can start with one awesome company that I found a few months ago: ECOTOOLS. These guys really are awesome, they make really great cruelty free brushes with synthetic fibers, bamboo handles and recycled aluminum ferrules. Unlike some synthetic brushes these are incredibly soft and very well made - you'll have a hard time believing they're not made from hair! Their selection is still quite small but the ones available are all sorts of awesome and I thoroughly recommend them. They also make bath products and make up bags - and even use responsible packaging.
If anyone out there has any recommendations please feel free to contact me and let me know!
