Launched in 2024, this Amazon KDP business publishes in the yoga, survival, and cookbook niches. The catalog includes multiple category-leading titles, with the top two books rated over 4.5 stars and one ranked as the #1 Best Seller in Exercise Injuries & Rehabilitation. The top-performing title contributes around 40% of total revenue, and the business experienced strong growth throughout 2025, with continued significant growth in recent months. With books successfully positioned across major English-speaking markets, the business benefits from a strategic, process-driven approach to reviews and customer engagement. 100% of revenue is generated through Amazon KDP. The books are written by an agency with other services, such as cover design and editing, handled by freelancers. The seller has implemented automated systems that drive consistent review acquisition and customer satisfaction via freebie distribution, helping the books outperform competitors in visibility and engagement. Notably, books in “Rest of World” markets have been generating consistent profit for 5+ months without any paid advertising, highlighting untapped scaling opportunities. With proven demand, scalable systems, and global traction, this business presents an attractive opportunity for buyers seeking a growth-stage KDP brand with strong foundations and upside potential. Disclaimers: The P&L includes add-backs for books that have been unprofitable in certain markets, including a survival book for which U.S. sales have been excluded. Although this book has become profitable in the past months, it remains excluded from the P&L, offering potential upside for the buyer going forward. In March 2026, books currently excluded from the valuation multiple generated approximately $1,500 in net profit. These profits are not reflected in the current valuation multiple and, if sustained or scaled, could represent tens of thousands of dollars in incremental profit over an annual or multi-year period. Buyers will have the option to either take over the full KDP account or merge the books into an existing account. If a merge is chosen, historical data (ads, analytics, account history, etc) will not transfer. Please note that KDP, ACX, Ingram Spark, and Draft2Digital payments are delayed for 30-90 days, so there will be residual revenue due to the Seller. This will be reconciled during the migration process.

The brands primarily target the women's market, offering readily accessible and discreet personal security devices designed to provide peace of mind and protection against assault and theft.

A significant portion of the products are locally sourced, and the business has consistently achieved strong year-over-year revenue growth exceeding 50%. Primarily selling in the United Kingdom, the business has recently secured compliance approvals to expand into other markets, presenting substantial opportunities for continued growth. Depending on the product, inventory is sourced from either a local UK-based supplier or a Chinese supplier. Some products are self-stored and then drip-fed into Amazon warehouses.
