Like they said in showbiz, there is no bad publicity.
Which company would complain if they get more views, hits, or costumers?
Making money is the main goal of running a business.
If you ask me, it could easily be a eye opener for him , when you send him posts about his company.
Or how about this, this case is a nice example for future cases.
Then you might as well create a review in @steemholidays about companies, and after creating a review, send those post to the companies, then you create a win win situation.
They see what steemit is, and because they see a serious review about there company, then they might join because they see actions, instead of another business deal, what many others ask him as well.

That's mostly the case, when you got a company.
He maybe sees it like, that you are another company who want to sell gold.
It would be different if you show him actions, same logic counts for every company out there.
And you give our Steemians here a nice review to spend our well earn steem coins.
I think after this, companies would join then, if they can get more costumers with Steemit and also if they know they can make more money with it, then what they have now.
That is another win win situation for them.
