SMM- 1 existing brand & launching a sister brand. Q=1 or 2 sm profiles?

We have a recruitment business with a SM following both on LI and FB. We are launching a global eLearning business. Our current sm following is not global and mainly UK, USA, IN based. Our eLearning will be for the global market although the same industry that we recruit for. We can’t decide whether to have 1 social media presence for both brands or to create a new social media page for our new eLearning business. We can of course promote our new eLearning business to the existing sm following and encourage them to follow the new business. The calls to action are different as one is promoting vacant roles and the other to drive purchase for eLearning. Should we have 1 or 2. Thanks so much
