This free course shows how three marketers tackle the same growth challenge — and why only one of them succeeds. You’ll understand the root cause of growth plateaus, learn how to build a system that compounds results, and walk away with a smarter way to scale.
Rick works hard but always feels behind. He jumps between tools, tactics and channels without a clear plan, hoping something will stick. He’s busy, but not effective — and can’t explain what’s really working. If you’re experimenting without strategy, Rick’s results will feel familiar.
Steve is skilled in one area — usually traffic — and runs disciplined experiments within it. He gets solid uplifts but eventually hits a ceiling. By ignoring the rest of the growth system, he can’t unlock scale or profitability. His wins are isolated, not compounding.
Sarah follows a structured growth system. She diagnoses bottlenecks, prioritises high-leverage experiments, and spreads her effort across marketing, sales and revenue. She gets better results with less work — because her efforts compound. In this course, you’ll learn exactly how she does it.
Most marketers push more traffic and eventually get stuck. Revenue depends on four growth engines—demand, funnel, pipeline and contract value. Lift each one by 33% and the gains compound to about 214%, far beyond what extra traffic alone can deliver.
Drive more of the right visitors without raising spend. Pick the best channel for your stage, then squeeze three quick 10% lifts—higher click-through rates, sharper copy and cleaner first-click experience—for a full 33% surge in engaged sessions.
Convert existing traffic into leads and booked meetings. Tweak forms, messaging and nurturing sequences so submission, activation and booking rates each rise with 10% each, stacking into a 33% uplift in meeting volume.
Boost pipeline win rate with smarter support for sales. Tighten qualification, ask better sales questions (that will help marketing too) and deliver clearer proposals; each change adds around 10%, together raising closed-deal rate by about 33%.
Grow revenue per customer without changing your service. Extend contract terms, launch focused upsells and refine value-based pricing. Three modest 10% improvements combine to a 33% jump in average contract value.
Inside the course, you'll follow Random Rick, Specialist Steve, and Solid Sarah as they each run six growth experiments at the same B2B company. They start with the same tools, budget, and goals — but their approaches lead to dramatically different outcomes. You'll see why chaos fails, specialism stalls, and structure wins.
This isn’t theory. You’ll get a front-row seat to the actual experiments, results, and tactics used — and learn how to apply them in your own work.

I’ve helped B2B service companies scale — not with random tactics, but with clear systems that align marketing and sales into one predictable growth engine. Built on 15 years of hands-on experience — helping teams move from random tactics to repeatable, scalable results.

Because it’s the first thing I give any team I start working with. It’s the foundation of the Solid Growth System — and it’s too useful to keep behind closed doors. I’ve seen it help dozens of marketers think more clearly and operate more strategically. I decided to share it freely so more people can benefit from the system, not just my clients.
It’s for marketers, founders and commercial leads working on B2B service growth — especially if you're stuck in tactics, juggling too many priorities, or looking to grow into a strategic role like Head of Growth. It’s not about specific channels. It’s about how to structure your thinking to drive compounding results.
No. This is a complete, self-contained module that teaches you the core of the Solid Growth System. It includes real examples, a fictional but realistic case study, and a framework you can apply right away. There is a full course available if you want to go deeper — but this is valuable on its own.
It’s six short videos — around 45 minutes total. You can complete it in one sitting or spread it over a few sessions. Everything is self-paced and available immediately.
I've been a marketer for 10+ years, and this course helped me elevate my thinking and day-to-day work. The framework is a helpful visual for optimization that's easy to follow, and breaks it down so you can find different avenues to reach your goals. Highly recommend!
It is actually Solid! As a designer working in marketing, I learned a lot from this course and it helps me better understand the growth issues my clients have, I can offer my clients additional value by pointing these out. And I gained insights on how to approach scaling, starting my projects.
