If you’re struggling to know whether your book will sell — or how to afford professional production — a disciplined pre-sale can solve both. In this 8-minute episode Dan Desmarques walks you through a five-step Pre-Sale Validation Sprint: validate the concept, create a minimal pre-sale offer, run a focused micro-campaign, use collected revenue to fund audiobook/cover/editing, and convert early buyers into launch advocates. You’ll get explicit prompts for copy, pricing, and messaging you can test in 24 hours, plus a concise case study of an indie nonfiction author who turned a $700 pre-sale into a funded audiobook and a 3x launch spike. This episode keeps tactics practical, ethical, and KDP-compatible — no hype, no shortcuts. By the end you’ll have a one-day action plan to validate demand, a checklist for deliverables, and the exact language to invite pre-buyers to become your first promoters.
