Case Study: Proofbound achieves rapid AI book-generation MVP launch and lands first B2B customer with Hal9

Hal9 Helps Proofbound Launch AI-Powered Book Generation

Proofbound is a startup transforming publishing by enabling businesses to create custom, print-ready books from simple prompts. Facing a tight timeline to win a B2B marketing-agency customer, Proofbound needed an AI-powered MVP with an intuitive UX that could generate high-quality, printable book content in under 30 days. They engaged Hal9 and the Hal9 Platform to build that solution.

Hal9 delivered a rapid, collaborative build using the Hal9 Platform—creating a web app that converts prompts into markdown-formatted books, an interactive preview for refinement, and workflows that integrate tuned generative models; the prototype was transitioned to a scalable AI API for custom frontend integration. As a result, Hal9 shipped a fully functional MVP in under 30 days, helped Proofbound land their first B2B customer, increased personalized sales engagement with professional outputs, and provided a scalable foundation for future growth.
