Take my case for example.

My personal brand (MrEmogical) helps business owners and aspiring entrepreneurs with business growth and personal development content.

My business brand (Paycheck To Profit) caters to millennials and gen-z who wish to build a profitable money mindset, get financially literate, want to manifest wealth using the law of attraction and achieve financial freedom.

Is there a lot of overlap (of audience) between both the brands? 100%
