Advance chapter
Sparkle with or without AI
Use AI as an editor and thought partner without sanding off the parts of your writing that sound like you.
Coming in 2026
AI can make you faster. It cannot make you right.
Selling in the Age of AI is a practical field guide for technical salespeople and GTM professionals who want to use AI without outsourcing judgment, trust, preparation, or the ability to read the room.
What you get
Useful now. Not a promise of something later.
The chapter and resources are ready now. The book is coming in 2026.
Foundation
Style Guide + AI Guardrails
Teach AI how you communicate, protect confidential information, test assumptions, and keep human judgment in the loop.
Practical workflows
Full Prompt Library
Working prompts for sales intelligence, influence mapping, meeting preparation, follow-up, buying-process analysis, and risk review.
The point of the book
Speed is useful. Judgment still closes the gap.
AI can summarize calls, research accounts, draft follow-up, and organize meeting notes. It cannot tell you whom the client trusts, where the political risk sits, or whether the deal is good for both sides.
The more AI accelerates routine work, the more valuable human judgment becomes.

This is not a book about replacing sellers with automation.
It is about using AI to do routine work faster while preserving the judgment, trust, and human understanding that complex sales still require.
