Anchored by the modern classic Never Split the Difference , the set pairs a world-renowned negotiation masterclass with growth and profit-focused reads aimed at founders, managers and entrepreneurs. Supplied brand new in paperback, it's an efficient way to build a practical business library covering four different specialisms in one purchase, ideal for self-starters, teams and gift-buyers alike. About the Books Never Split the Difference , by former FBI lead international kidnapping negotiator Chris Voss, translates high-stakes hostage negotiation tactics into everyday business and personal use — covering tactical empathy, calibrated questions and how to steer conversations toward better outcomes without conceding value. Blitzscaling , by Reid Hoffman and Chris Yeh, explores the aggressive, high-speed growth strategies used by category-defining technology companies, examining when prioritising speed over efficiency is the right call and how leaders manage the resulting organisational chaos. The Profits Principles is a pragmatic guide for business owners looking to move beyond trading time for money, focusing on systems, margin improvement and building a company that generates profit sustainably. Scale Up Millionaire , by entrepreneur Gordon McAlpine, focuses on sales mastery and the mindset needed to grow a business with confidence and control. Together, the four titles give a rounded view of negotiation, growth, profit and sales — each written from real operating experience rather than pure theory, and each structured for practical, chapter-by-chapter application. Four specialisms in one set: negotiation, scaling, profit strategy and sales, without buying each book separately. Practical, actionable frameworks you can apply directly to a business or role. Experienced authors: insight from an FBI-trained negotiator, established Silicon Valley operators and working entrepreneurs. Great for teams: ideal for leadership book clubs, onboarding kits and coaching programmes. Thoughtful gift: a ready-made business library for founders, managers and career-changers.
