What you guys are up to sounds cool.
I’m not sure to what ends you’d like to have 1 brand?
It seems to me that you’re more of a collective? Ie a group of individuals working together sharing space and back office functionality with some slight customer crossover?
To me, having just one brand would be a little odd as a customer. Would I look to my barber to mix me some sweet beats, or buy a hoodie. I’m not sure.
If you’re like D12 with your own rap names underneath it makes sense to have the one overall brand, but if they’re markedly different offerings, I’d advocate the collective approach for resources, and keep your own independent brands running underneath. That also allows flexibility for the individual business owner to sell/grow etc. You’ll avoid the pitfalls of too many shareholders being unable to reach an agreement on, well anything….
