I think the name for what you are offering is called "Business Intelligence".

Now you need to be able to handle objections.

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".)

I like this a lot, as a unique selling proposition. The improvements you made to your site based on this also look good. By identifying this market segment, you can tailor your advertising more sharply, which will hopefully make it more effective than if you were trying to market to any/all segments.

How does it differ from Apache NiFi?

The buZzzzwords these days are: NoCode/LowCode tool for data insights.

Generally I suggest deleting most of the text above the screenshots.

I think you have a winner if you could make this Jig helps CEOs/CTOs get custom insights about their businesses without ANY developer time.
