I want to see a screenshot of the analytics page before providing my email.

I have put the screenshots from portion of the analytics page. What do you find missing about it?

The page looks decent overall, however, I'm having trouble imaging how it works. Would someone simply give an instagram id, then get nice analytics?

I wonder if pricing is high, what about a non-expiring free tier for 1000 posts?

Did you segment your users and check their conversion rate. Looking for conversion rate overall is a bad idea, try to segment logically and look for conversion rates.

I use facebook ads and it only have 1 very specific segment so far. It's 20-40 person who works as a marketing / social media admin.

To me, this looks like something that probably ought to be sold B2B and targeted at companies which conduct campaigns on behalf of clients because the value is in replacing their existing tooling. It might work as a 'white label' type service.

Under that premise, the way to sell that sort of service is with regular B2B practices: cold calling, trade shows, industry publications, etc. The targeted demographic from Facebook is not primarily people who are empowered to make strategic business decisions. The decision makers at the media companies are going to be fewer but have much more influence. At the lower end of the employment hierarchy, marketing staff are mostly just trying to keep their job and will be risk adverse (and depending on a new service is a risk).

Good luck.

*person with age between 20-40

In my view for your product 20-40 is too big. What's your conversion rate if I may ask?

Minor suggestion: "Save your time with one click, shareable, reporting"
