About Solid Growth

For 15 years I’ve helped B2B service companies replace random tactics with reliable, repeatable growth systems. Solid Growth exists to share those exact systems—so any ambitious team can scale with less guess-work and more compounding wins.

What I've done since 2010

A quick look at projects, and lessons that shaped Solid Growth.

2010

Affiliate websites

My growth journey began at Blue Canal where we built 19 affiliate sites in insurance. We made learning about Google Ads fun by labelling every Google advert we wrote and competing to see whose copy would win. Losing 2 crates of beer to my co-founder pushed me to master copywriting, SEO and paid advertising. The portfolio grew into a key source of insurance traffic and we sold it to an insurance company in 2017.

2012

Seven online stores

I co-founded an e-commerce holding for a media group and guided growth for seven Lightspeed stores. While completing a seven-month CXL conversion traineeship I applied paid-media, A/B-testing and cross-sell tactics across the portfolio. Revenue rose across all shops and we sold our stake to the group’s majority shareholder.

2014

Smartphone insurance

After Monobrands, I joined CoverYou Smartphone Insurance as Partner and Head of Growth. I built long-tail landing pages for every current and upcoming phone model, balanced SEO with precise paid campaigns and introduced testing and retention flows. Customer acquisition costs fell, lifetime value improved and a German insurer acquired the business, including my stake.

2015

Teaching growth strategy

When the Talent Institute launched in 2015 I co-created its first beta training. In 2016 I became a permanent trainer, delivering full-day workshops on growth strategy and the first 100 days as a growth hacker. Across ten years I have taught every cohort, refining my framework through their questions and sharing my enthusiasm for continuous learning.

2016

NU.nl optimisation

The chief digital officer at Sanoma Group asked me to embed data-driven decision making after working with him in the Innovation Lab. We decided to to start with A/B testing for , one of the Netherlands’ five largest websites.

I created an optimisation roadmap, carried out customer research and launched the site’s first A/B tests. Early gains prompted leadership to establish an internal experimentation agency that still guides data-driven decisions and experimentation at Sanoma (now DPG).

2018

Advisory board Decathlon

Since 2018 I have served on the Decathlon Netherlands e-commerce advisory board, providing quarterly guidance on growth. Seeing the team expand rapidly during Covid was exhilarating and I am proud to have played a role.

The project also tested my growth framework at enterprise scale and confirmed that it works for larger organisations. Over the years I have watched revenue rise and the team’s capability strengthen as data-driven experimentation became part of their culture.

2018

Founder Polaris Growth

At Polaris Growth, a Klaviyo-focused e-commerce agency, I directed client strategy and grew the team to 11 specialists.

I built inbound content, led sales, and ensured client roadmaps combined email, paid advertising and conversion optimisation.

When my focus shifted to holistic growth and my co-founder chose Klaviyo specialisation he bought my shares, allowing both our paths to thrive.

2021

Co-founder Replicable

I co-founded Replicable and served as shareholder and strategic advisor.

My focus was building the inbound funnel and lead-generation engine that helped the company become one of only two Premium agencies in the Netherlands.

After guiding early growth I sold my equity to my co-founder so I could devote full energy to Solid Growth.

2023

Fractional head of growth

Kees de Boekhouder
Fractional head of growth for 5 months. Aligned OKRs, improved HubSpot, launched weekly experiments. Revenue hit target and a new full-time head of growth took over a proven system.

Yaya
Hired to raise direct-to-consumer sales and smooth the leadership hand-off. Streamlined funnel, set OKRs, ran rapid . Sales velocity rose and a permanent head of growth stepped into a ready rhythm.

Ligo
Growth adviser before sale. Refined lifecycle stages, automated hand-offs in exposed deal metrics. Shorter sales cycles helped position the firm for a successful acquisition.

2025

Recorded B2B growth course

Solid Growth turns random B2B marketing effort into a compound growth engine. The flagship delivers 45 on-demand lessons across seven modules that walk marketers through kaizen growth, demand generation, funnel optimisation, sales pipeline management and lifetime value lifts. Students receive a plug-and-play growth scorecard, revenue-forecast calculator and experiment backlog so they can apply the 12-step framework straight away.
