or 15 years, I've been building growth machines that drive predictable revenue. I've done it for my own businesses and for B2B companies across different industries. Now you can learn how to build it yourself, or let me build it for you.

Solid Growth was founded on a simple idea: growth shouldn't feel chaotic. Most B2B companies run tactics without systems. They hire agencies, chase trends, and wonder why nothing compounds. We fix that by building the infrastructure that makes growth predictable.
We work with B2B companies doing €500K to €5M in revenue who want to own their growth machine. That means setting up the right tools, building a weekly rhythm, and training teams to run experiments independently. Some clients take the course and do it themselves. Others hire us to build it for them.
The business is built around three core offerings: a video course for marketers who want to learn the system, done-for-you consultancy for companies that want it built faster, and free resources to help anyone understand how B2B growth actually works.
Solid Growth B.V. is based in the Netherlands and has trained over 1,500 marketers since 2010. The methodology has been refined across hundreds of client engagements, from early-stage SaaS to established agencies. It works because it's not theory—it's trial and error, distilled into a repeatable system.

I started in paid ads when data-driven marketing and growth hacking were just emerging. I moved into conversion optimisation, co-founded several companies, sold them and worked as a fractional Head of Growth for B2B clients.
These are the principles that shape how I work. They're what I've learned from building systems that succeed and watching others fall apart.

Tactics work when the system behind them is solid. I build machines where traffic feeds the funnel, the funnel fills the pipeline, and the pipeline validates your product. Without infrastructure, you're firefighting.

One brilliant campaign won't save you. Small improvements across all four engines compound into exponential growth. I build a rhythm where your team runs experiments, measures results, and optimises.
I don't believe in agencies you depend on forever. I build the infrastructure, train your team, and hand it over. You own the machine when we're done. My job is to make myself redundant, not keep you hooked.
These are the platforms I'm certified with and recommend most often. They form the backbone of the infrastructure I build for clients. I work with them because they're reliable, and yes, I earn affiliate commissions when clients sign up through my links.
All in one CRM with marketing, sales and service, strong when you want one system that teams adopt.

These are the most common questions I get about how I work, who I work with, and what to expect. If your question isn't here, book a discovery call or send me an message.
Mostly B2b SaaS, agencies, consultancies, and ecommerce companies selling to businesses. I've worked with startups and multinationals across industries. The common thread is they want to build a system that scales, not just run more tactics.
Yes, but only after the build phase (see here). I don't advise from the sidelines—I build hands-on first. Once the system is running, you can hire me as a fractional Head of Growth to optimise ongoing. That's optional and month-to-month.
Yes, occasionally. I join podcasts or write guest posts when the topic aligns with what I teach. Reach out with details about your audience and what you'd like to discuss, and I'll let you know if it's a fit.
Yes, I do speaking engagements. I typically talk about building growth systems, diagnosing bottlenecks, or how to structure a full-funnel approach. Reach out with event details and I'll let you know if I'm available.
Selectively. I only work with a few clients at a time to stay hands-on. If I think there's a fit and I have capacity, we'll move forward. If not, I'll point you to the course or suggest alternatives. Book a discovery call and we'll figure it out.
This is a selection of the companies I've worked with on growth. I've founded and sold two marketing agencies (one for ecommerce, one for B2B) which is why you'll see ecommerce brands here too.

Ewoud provided me with the right tips to gain more focus in my work, set long- and short-term goals and make more strategic decisions. Thanks to Ewoud, my day-to-day work is clear and fixed, whilst working on goals that help our business grow.
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!

Ewoud helped us find impactful retention funnel improvements with a framework suited to our business model. He challenged our approach with the right questions. Overall, Ewoud combines high-level strategic thinking with detailed campaign expertise.
I really loved the combination of theory with the hands-on material and tools that made everything very actionable. This course is relevant for anyone working in B2B: whether you are new to growth or want to optimize your marketing or sales strategy to reach your business goals. Even with my background in growth, I definitely learned new stuff. And for those who don't know Ewoud, he's one of the best Growth Experts I know!
The Growth Session with Ewoud was a confirmation for our marketing team about the direction we're taking. Next to that, Ewoud gave the team an outsider perspective that was sharpening our focus and execution.
Helpful to everyone in all levels of their marketing career. The characters used are a great way to show scenarios and help understand the input and output of existing marketing strategies. The content is explained well and I feel like I already picked up some new tricks and ideas for my next project. Thanks so much for this course!
This has helped me so much in my growth journey. Especially module 6 about retention, upsell and pricing was an eye opener.
The sessions were very useful in dissecting our key KPIs (Revenue and CLV) into the underlying metrics and their interrelationships. By building KPI trees and customer journeys, I gained insight into the types of drivers that can accelerate certain growth.
Great course for those who want to start optimising their webshop and online marketing but don't know where to begin. During this course, you'll receive tools with which you can immediately get to work!
Really enjoyed the course. You can work at your own pace and the content is very relevant to refresh my 'growth' knowledge and learn new things!
Ewoud brings it back to simple examples and personas, this really helps. Next to that, the message is clear, focus and stick to the plan, the power of compounding small results is the gamechanger here!
The knowledge Ewoud shares is presented in a clear and logical way, and his way of teaching makes it very exciting. The lessons I’ve learned have been invaluable and there is always something new to learn!
Had a very nice training from Ewoud! Gave lots of tips and tricks to start working in a structured and focused manner. Definitely recommended!
Amazing workshop. Thanks a lot. Really helped me (re)organising my planning, agenda and email with loads of practical tips. But most importantly, a wakeup call to change my mindset towards tasks, priorities and planning.
We aimed to improve our customers' growth strategies, and Ewoud's in-depth knowledge and steady flow of new information made every session enjoyable. With newfound inspiration, we quickly saw increased customer results. We highly recommend Ewoud, 5/5.
Ewoud has helped me well in identifying the biggest challenges of my business. By listening carefully and asking the right questions, I realized that the biggest 'problems' I thought were hindering growth are not the issue.
Had a very inspiring workshop where you really learn to look at the big picture and thus understand which levers you can pull to increase profits.
We are a startup and we worked with Ewoud on our marketing strategy, and it was very helpful! His structured way worked well for us. So we really recommend working with Ewoud for strategic marketing plan and get advise on execution of it.
It's great that we can use our own customers as examples live and that we can immediately apply the learning points in practice during the exercises. Excellent!
By combining years of real world experience and theory into practice, this course presents an actionable and systematic map to sustainable growth. Starting from the first module, there are ample steps, tools, and tricks that can be implemented straight away. Would highly recommend to any start-up or B2B business looking to get to that next level.
Ewoud is a real expert: solid, step-by-step foundations for growth, taught and delivered with clarity! The fact that he's helped a lot of different types of businesses grow, in different niches, with different types of marketers and founders, over a sustained period of time, is reflected in the course. Would recommend to anyone that wants to learn and understand the process of how to grow any online business reliably.
Super nice training to have tools for optimising your e-commerce and marketing. Good to have a fresh look at this process again and to come up with new ideas! I would like to do a deep dive with Ewoud again to dive even more specifically into our data.
I enjoyed the Solid Growth workshop today. A nice variety of exercises and plenty of individual attention from Ewoud for the participants in the group.
Ewoud's lightning-fast strategic and creative thinking, systematic approach, and enthusiasm make his methods both fun and valuable. Despite our marketing experience, Ewoud provided fresh insights and practical tips for each funnel step through his probing questions.
