Tech stack is literally a Claude skill to write the proposals. I took that same prompt and put it in Lovable and selling access to it on Stan Store. I don't know how to use Vercel yet. I read your substack about what tools you've kepts and dropped. As for marketing, I'm marketing it mostly on Threads, IG and to my email list about once a month. No hard pushes yet, but I will! Thank you for the feedback.
