Not enough sign-ups to justify finishing the build. The engine works and the spec is locked, but without authors saying they want it, the wrap tool stays on hold.
Enough authors on the interest list to make a launch worth the work. No fixed number — when the signal is loud enough, the build resumes.
Take your ebook cover, compute the spine for your page count, build a KDP-spec wrap PDF, and typeset your back-cover blurb. Print-ready, KDP-error-proof.
v1 was planned for novels, memoir, and business books on standard 6"×9" trims. Illustrated and large-trim were on the roadmap.
I built Coverfa.st because I hated that async limbo between finishing a manuscript and seeing the paperback live. If you have your ebook cover, you have your paperback wrap. KDP-ready in 120 seconds — no waiting on a freelancer, no trim-size rejection emails.
