If you want to setup a consulting firm, you cannot sell yourself as experts on Go and Angular. You need to find some enterprise platform that a lot of businesses are already, and become really good at working with it. Then you can sell yourselves as experts on that particular technology.
I already gave you the example of a consulting firm that does nothing but Magento.
That's great advice, thank you! I never thought about that yet. I don't clearly understand the reasons behind it but I will definitely research this.
Thank you.
Great advice. You need to differentiate yourself. Everyone these days pitch themselves as Angular experts or Ruby expert. Those skills are commodities.
