We updated our landing page using quotes from customer interviews

Ooh, that sounds really cool - I love flowcharts, especially if they're interactive. But my suggestion would be to show more examples of how that works in practice. I've found gifs to be a good solution without compromising on the speed of your lander.

I'd also use the content from the image (for me it's very small so I can't read the text) as a separate section to explain what Nodemap is, who it's for, and how it should be used.

You could even rephrase the hero copy to make it punchier: "Share interactive flowcharts with detailed content" and "Share engaging flowcharts without compromising on the content." cue CTAs.

But I'd definitely like to see more examples before trying out a demo.

Hope this helps!
