This is great marketing, nice job. Have you ever read Traction[0]? They call this engineering-as-marketing[1]. I built an open-source version[3] of Baremetrics when I was working on a loan marketplace for SaaS companies[4]. It did ok! I'd consider open-sourcing the tool since it's not your main business.

I like it. I would prefer if your play the chime demo counted upwards instead of being rng each time you click, but that's just a tiny nitpick.

I've been building on top of Stripe for awhile now, and I've always wanted a way to see live charges as they come in. I also needed an excuse to finally learn WebSockets/ActionCable, so I made this.

I plan to add more sections of data in the future, and maybe some goal tracking, so that people can track progress toward their revenue targets (and share them with others for support!)

One tiny suggestion - use "font-variant-numeric: tabular-nums;" in the styling. It'll stop the UI moving around when there's a number that starts with 1. https://developer.mozilla.org/en-US/docs/Web/CSS/font-varian...
