Ask HN: Stealth Co-founder?

Having recently bootstrapped and launched a workflow SaaS app, my (non-technical) co-founder is working on the marketing of it. The problem is, his current fulltime job prevents him from being public about his involvement so anything he posts or signs up for is all run through my accounts (i.e. LinkedIn). While that's all well and good, it adds more administrivia to my plate as I'm left responding to any and all correspondence that comes our way, which takes my focus off of building a solid product. I knew going into it that he may have to operate on the DL, but I ignored how this may impact me as I've been heads down on the tech side. Don't get me wrong, I have no problems doing my part to market the app, which I do, it just is seeming less like a 50/50 effort and more on me.

I was curious as if anyone else has dealt with and handled a similar situation. Thanks.
