I was pumped when I found SaaS Playbooks was a domain that was set to expire. I put in a bid for it and was lucky to grab it.
I have sat on this domain for years trying to figure out the right thing to build with it. But the first version of this will be Notion based templates for common SaaS marketing strategies and tactics. I will write more about this in the future but I will attempt an AI/SEO play to create hundreds of blog posts to see if I can get this domain ranking.
