After launching Scrapbook, my growth tactics database, a couple of months ago, I've seen a couple of other projects that could be called 'productized Airtable databases', or Scrapbook for X ;)
The stack is super simple: Airtable as the database, Gumroad as an easy way to handle payments, and Carrd (or any other landing page builder) to build the website.
One key thing (at least that's how I was thinking when creating my landing page) in all of them is giving out a part of the product as a preview. This way users get some value from your product even before they buy it - as in a free trial.
So I just wanted to give these projects a shout-out:
https://ventureslist.com/ - resources to help you get funding
https://gumroad.com/l/triggered - B2B buying intent signals
https://podcastgrowth.guide/ - tactics to grow your podcast
https://integreat.cloud/ - apps you can integrate without code
https://top50slack.com/ - Slack groups database
Honestly, I'm surprised not to have seen a sales tactics database yet ;)
