What does this offer (me the CEO/CTO) that isn't done with Tableau or PowerBI?
Those tools get me custom insights about the business without using any developer time; the work is generally done by entry-level data analysts or accountants.
(This is not to say your idea is bad, but this is an objection you will need to have a response too, like "this tool is cheaper". If that response seems to get traction you might change your pitch to "it gives you 80% of Tableau, but at 20% of the price".)
Generally I suggest deleting most of the text above the screenshots.
