As a first MVP, I chose to whip up a landing page that explains the concept and includes a call to action.
I used whimsical to generate a first set of wireframes (https://whimsical.com/K8w8UPCiWpTS5wW96anwBT) and set up a Mailchimp audience to store incoming email subscriptions.
The logo was designed using canva.com, but then refined in a vector graphics tool.
So far I'm quite satisfied - 9 potential users subscribed in the first 10 days. A static page isn't really descriptive though, that's why I'm going to add a short video at the earliest time possible.
