You are going to go with IBM because nobody every gets fired for buying IBM.
> wanna sell me something, anything? you're out.
Advertise? you're out. Have a website? you're out. Go on the Shark Tank? you're out. Do a "Show HN"? you're out.
Reply to an open call to tender? you're out.
> I don't know what makes you say that
"CFO". IBM is the classic choice of the CFO class - they dont want to get fired so they a) dont make a decision or b) chose IBM because they were not "selling them something" (except for all the sales and marketting they do)
If so, that has not been my experience. In my business I typically select against products or services that cold email/call me. But that’s never been a problem. When I need to find a third party solution I start educating myself on the topic and search for vendors. It’s not that difficult.
