Nick Mastro is an author and operator focused on decision frameworks for AI at work. He wrote The Room System and founded Greater Results. Alongside that work, he does senior AI and product work inside an advertising agency — where strategy, delivery, and human judgment meet real client work.

Nick Mastro is a senior AI and product specialist at an advertising agency in Richmond, VA, and the founder of Greater Results. With 20+ years across marketing, design, technology, and digital strategy (including SEO/SEM, email, social, programmatic, CTV, workflow automation, and human-centered product work), he connects strategy, delivery, and human judgment where models meet real client work. He’s a Meta Certified Media Buying Professional.

He helps businesses make better decisions with AI through judgment-first frameworks, not prompt theater. He builds review habits for teams that already use AI and still get polished answers that miss the person closest to the outcome. His through-line is simple: ask who’s missing from the room before the model runs, treat AI output as a hypothesis never proof, and validate what matters with reality.

When he’s not writing or building, he spends time with his family, including his four kids.

Nick Mastro wrote The Room System.

Amazon title:
The Room System: How to Find the Missing Perspective, Make Better Decisions, and Get More Useful Work from AI

Cover / manuscript subtitle:
A Practical Decision Framework for Smarter Human-Centered AI in the Workplace

It is a decision framework — not a prompt book. It will not show you “what to write.” It changes how you think before you talk to AI, so you find who’s missing from the room and treat AI output as a hypothesis, never proof.

Nick kept seeing the same pattern in real work: a polished draft, a confident tone, and a missing person — the customer, the teammate, the person who had to live with the decision.

He wrote The Room System for that moment. Not a better prompt. A better question: who’s missing from the room?

The book gives the full framework: Ask → Empty Chair → Context Card → Room Report → Use / Validate / Explore / Reject → validate with reality → Next Chair only when a new question earns it → Five-Minute Check when stakes are real but time is short.

REVIEW before REWRITE. Polishing incomplete work makes incomplete work look better. Perspective first.

Prefer to practice the habit? There’s a companion 17-minute self-serve course — a review-habit walkthrough focused on Ask, Empty Chair, and review-before-rewrite. Mindset and habit, not prompt engineering.
