Our Skills

The MYYM Group can be your one-stop solution for all your business needs. Whether we started our collaboration by us helping you to raise funds, the relationship doesn’t necessarily have to end there. We can then help manage, even market whatever it was, you needed those funds for, in the first place.


Core Services

We have decades of industry experience between us, making us true masters of what we do.


Everything starts with Investment. Like water being the major life-force for all things living. So is Money, for all things business. We have the know-how, as well as all the right connections you’ll need, in order to get all your business ambitions off the ground and flourishing. Give us a call and we’ll get the process started.


In the beginning, God created the Heavens and the Earth. We certainly can’t top that, but we can market the hell out of it. If you’ve made something that you’re proud of, and you now need to shout about it, then why not let us do the creative brainstorming for you, and bring whatever it is you’ve created, into the light.


Oil Mining & Gas, or OMG. Yeah, we certainly have our fingers in a lot of fundamental industry sectors. It makes good business sense to have know-how in sectors that are essential in life, as well as within business. We can offer advice, as well as solid business partnering opportunities within these fields.  


We construct from the bottom up, and from the inside out. We offer Interior Design services, as well as Architectural. No job too small, and certainly never too large. Helping to keep the roof over your head, as well as get you to work on time via roads and bridges. Need something built? Well, you know where to find us.
