Thanks for your time! Basically, business in General, understading whether or not The company numbers are doing ok or not, how much to invest in the tech team, cut costs and so on.

Ok. Thanks. Sounds like you are mainly struggling with topics around numbers, investments, costs etc.

Unfortunately I don't have a specific resource to recommend.

But I can share from my experience.

I have advised some tech people on this specifically and it usually boils down to: explain everything you want to do in $ figures. $s is the language the CFO and the CEO speak. So you need to translate anything into their realm.

Most tech folks talk team, tech, servers. CFOs/CEOs don't bother and don't understand. So try to calculate some basic business cases for most of your requests and for their questions to you. Nothing basic, but have some rudimentary logic ready.
