No-code platform Mintdata - anyone used it?

It’s a Bubble competitor. Seems pretty slick. Editor has multiplayer mode, and takes a spreadsheet-like approach to databases & workflows. Like Figma meets Google Sheets. I took a demo from their CEO today. They have a few dozen enterprise clients but not much on the consumer end yet.

Anyone heard of them / used it? Free to get started. Think I might give it a whirl for my next project.
