My former colleague, and likely eventual business partner, is still collecting a regular pay check (I am not.) Once my business gets some more traction, he will join me, or at least that's the plan.
I am probably over thinking this, but I have some practical and ethical issues as to what to call him.
His skills and abilities are worth highlighting when I talk to potential investors and customers. Nonetheless, he is not my employee. I say that he is my business partner, but in a legal sense, he is technically not, so I do not want to refer to him in a written context as my "partner." (Also, I do not want to put his job at risk.)
I would like for him to have a descriptive moniker that highlights his importance to our overall efforts, but that does not misconstrue to others that he is currently 100% committed, since he is working full time somewhere else.
I guess I can call him an "Adviser", but I was looking for something with a little more "gravitas."
