Tim Castle’s Magnetic Influence arrives at the right moment. As artificial intelligence begins to reshape how we prepare for negotiations and make decisions, the human element of influence becomes even more important. This book offers a thoughtful perspective on how negotiators can combine technology with timeless human skills such as trust, connection and emotional intelligence.

Castle reminds us that while AI may enhance analysis and preparation, successful negotiations will always depend on our ability to understand people, build relationships and create meaningful outcomes. His framework encourages readers to strengthen the human side of negotiation while embracing the tools that will define the future of business.
