Word of mouth growth through customer obsession and Net Promoter Score

Executive overview

Most companies spend on marketing to acquire customers. A better model invests that budget in making existing customers so impressed they recruit new ones.

The framework: measure advocacy with Net Promoter Score, act on the feedback, and raise the bar until word of mouth drives growth on its own.

Wow your customers so completely that marketing becomes unnecessary.

Why wowing customers beats marketing spend

• Walt Disney's principle: do your work so well people return and bring friends
• Jason Gaynard (Mastermind Talks) spends nothing on marketing or sales
• Every element of his events — venues, meals, speakers, curation — is deliberately exceptional
• The result: CEOs refer peers organically, fuelling continuous community growth

How to measure and improve advocacy with NPS

• Survey all customers every 3–6 months with one question: "On a scale of 1–10, how enthusiastically would you recommend us to a friend?"
• Promoters: scores 9–10; Detractors: scores 1–6
• NPS = % promoters minus % detractors (range: −100 to +100)
• Target: above 50 to sustain word of mouth; above 85 to drive it at scale

Turning survey responses into improvements

• After the survey, ask one follow-up: "What's one thing we could do to have you refer us even more?"
• Prioritise the most common feedback and easy wins that create visible impact
• Feed improvements back into the experience to raise the next NPS cycle
