Course overview
What you'll learn
Byron Sharp's How Brands Grow dismantles marketing myths with empirical evidence: brands grow by reaching more buyers, not by building loyalty; differentiation matters less than mental and physical availability; heavy buyers aren't your growth engine. These findings contradict decades of brand management dogma. But recognizing these patterns in a how brands grow summary is different from recognizing them in your own campaigns, competitor strategies, and category dynamics. Most marketers nod along, then revert to targeting 'brand lovers' and obsessing over engagement metrics that don't drive growth.
This course makes you work with Sharp's laws through structured practice. You'll analyze case studies of brands that grew (or stagnled) based on penetration versus loyalty strategies. Podcast episodes debate whether certain categories break the Duplication of Purchase Law or validate it. Flashcards drill the Double Jeopardy pattern until you can spot it in market share data instantly. Written assignments ask you to audit a brand's distribution strategy against physical availability principles, with AI feedback on your analysis. You'll calculate reach metrics, interpret panel data, and distinguish between evidence-based growth levers and feel-good brand theater.
This course is for marketers, brand managers, strategists, and founders who want their growth strategies grounded in what actually works across categories, not what sounds compelling in a deck. If you've been taught that loyal customers are everything, or that emotional branding trumps distribution, expect your assumptions challenged.
Course curriculum
8 modules, designed for mastery
Penetration Drives Growth: The Empirical Case Against Loyalty-First Strategies
~75 minUnderstand why brands grow primarily by acquiring more buyers, not by increasing purchase frequency among existing customers. Analyze the evidence from consumer panel data across categories.
Double Jeopardy and the Duplication of Purchase Law: Patterns That Hold Across Markets
~60 minLearn why smaller brands have fewer buyers who buy less often, and why your customers also buy competitors. Apply these laws to competitive analysis.
Mental Availability: Building Distinctive Brand Assets and Memory Structures
~80 minExamine how brands compete for recall in buying situations through distinctive colors, logos, characters, and taglines. Audit real brands for mental availability strength.
Physical Availability: Distribution, Shelf Space, and Buying Ease as Growth Levers
~65 minStudy how ease of purchase—not brand love—determines market share. Evaluate distribution strategies and identify availability gaps that limit growth.
The Myth of Differentiation: Why Being Noticed Matters More Than Being Unique
~85 minChallenge the differentiation orthodoxy with evidence showing most brands in a category are similar. Distinguish between perceived differentiation and actual distinctiveness.
Targeting Light Buyers and Non-Customers: Where Real Growth Potential Lives
~70 minUnderstand why heavy category buyers are already buying you (if you're big) and why growth comes from light buyers and switchers. Apply this to segmentation decisions.
The 95-5 Rule and Continuous Investment: Reaching Buyers Not Currently in Market
~55 minLearn why only 5% of your category is buying right now, and why consistent broad-reach marketing builds future sales. Critique campaigns against this principle.
Applying the Laws: Auditing Your Brand Strategy Against Evidence-Based Growth Principles
~90 minSynthesize Sharp's framework into a diagnostic tool. Audit a real brand's strategy, identify departures from empirical laws, and recommend evidence-based alternatives.

Everything you need
Six learning formats, one complete experience
Every module delivers content across multiple formats — each chosen for a specific learning science reason.
AI-Generated Podcasts
Two voices — an expert and a curious learner — break down complex topics in engaging conversations. Listening activates different cognitive pathways than reading, deepening comprehension.
Structured Key Concepts
Clear, pedagogically-framed core knowledge organized for progressive understanding. Each concept builds on the last, creating a coherent mental model.
Real-World Case Studies
Applied examples from actual scenarios show how theory works in practice. Case-based learning bridges the gap between knowing a concept and using it.
Interactive Flashcards
Active recall — testing yourself — is proven to improve retention by 50%+ compared to passive review. Flashcards make retrieval practice effortless.
Quizzes & Assessments
Multiple-choice questions with detailed explanations test understanding and reveal knowledge gaps before you move on. Mastery-based progression ensures nothing is skipped.
Written Assignments
Writing forces deeper processing than multiple choice. Synthesize your learning by applying concepts to realistic scenarios, with instant AI-powered feedback on your analysis.

Built on learning science
Every format is here for a reason
Erudia courses combine five proven learning methods into one seamless experience — so knowledge sticks, not just passes through.
Spaced Exposure
Content revisited across multiple formats — audio, text, flashcards, quizzes — reinforces memory through varied repetition. Each encounter strengthens the neural pathway differently.
Retrieval Practice
Flashcards and assessments force active recall — proven to improve retention by 50%+ versus passive reading. Every quiz is a memory-strengthening event.
Synthesis Through Writing
Written assignments require deeper processing than multiple choice. When you explain a concept in your own words, you discover what you truly understand and what you don't.
Multi-Format Learning
Audio, reading, case studies, and interactive practice mirror how people naturally absorb complex information. Each format activates different cognitive pathways, building richer understanding.
Mastery-Based Progression
You can't skip ahead until you've demonstrated understanding. This isn't arbitrary — it's how lasting learning works. Each module builds on the foundations laid by the previous one.
What learners are saying
Real courses, real feedback
“I expected a surface-level overview, but the course actually got into altitude-specific soil biology, frost-resilient guild planting, and water management for mountain terrain. The case studies were specific enough that I could apply them to my own site. The podcast episodes were perfect for listening while working in the garden.”

“I've read the book twice, so I was skeptical a course could add anything. It did. The module on counter-strategies completely changed how I think about defensive positioning, and the written assignments forced me to actually apply the laws to situations I'm dealing with at work — not just passively absorb them.”
Mauritz Burenius
Author of Never Piss Off HR · The 48 Laws of Power
“This covered territory I haven't seen in any other course — residual valuation models for streaming libraries, probabilistic forecasting for franchise IP, portfolio construction across film, TV, and gaming assets. The quizzes caught gaps in my understanding I didn't know I had. Genuinely useful for anyone working in media finance.”

FAQ
Frequently asked questions
No. The course teaches Sharp's laws from the ground up through case studies and practice. That said, if you've read the book, this course will deepen your ability to actually apply the findings rather than just reference them.
The laws Sharp uncovered hold remarkably well across categories, including B2B and services, though application requires interpretation. The course includes exercises adapting the principles to non-FMCG contexts and discusses where category-specific nuances matter.
Sharp's data shows loyalty programs don't create disproportionate loyalty and that all brands have similar loyalty patterns (Double Jeopardy). The course doesn't say ignore customers—it says growth comes from penetration, not squeezing existing buyers harder. You'll work through the evidence yourself.
