For 21+ years I've helped tech teams turn developer & customer intelligence into product strategy, grounded in cognitive psychology and a habit of testing my assumptions. I help build communities, and the teams that run them.
1) Own your data, or at least be able to leave
2) Prioritise open standards
3) Local-first, cloud-optional
4) Apply the bankruptcy test
5) Resist subscription creep, but accept strategic subscriptions
6) Favour EU-based and privacy-respecting tools
7) Replace gradually, not all at once
For those who though I was joking about wearing clogs at @atmosphereconf.org: here's picture proof of me at Magento Live 2019 co-hosting the event.
Last one in the grass is from today: clogs are durable!
(also because I don't wear them like ever because it hurts like hell)
Do you also want "fun facts" in here?
Like "The Kingdom of The Netherlands has (land and sea) borders with these other countries:"
* Germany
* Belgium
* United Kingdom
* France
* Venezuela
* United States
* Saint Kitts and Nevis
* Dominican Republic (possible...)
I lean on two things that don't always sit together: a cognitive-psychology read on how developers and customers actually behave, and an experimentation
habit (those 500+ A/B tests at Randstad & JDE) to check what works instead of guessing. I'm
still learning, mostly in the open.
Cognitive psychology
Why developers and customers actually behave the way they do.
Business experimentation
500+ A/B tests at Randstad & JDE. Measure what matters, prove what works.
Community building
Helped grow the Joomla!, Magento, CRO.CAFE and Spryker communities.
(AI) automation
Reliable AI workflows and local-first tooling that earns its keep.
Guido has a rare ability to translate community insights into tangible business intelligence, and to bring the business closer to the community.
Svitlana Kulynych Head of Learning Experience, Spryker · worked with me at Spryker
Recommendation excerpts written by colleagues on LinkedIn
"Guido is a thought leader in community building and developer relations. Any company serious about building an ecosystem should talk to him."
"He can lead from the front, and he can let others lead. He will always give credit to his colleagues and team."
"Conversion rate optimization, psychology, leadership, and business are just a few of the topics he's spoken to at the highest level."
"I'm amazed at how quickly he adopts new technologies. For example, he rapidly mastered cutting-edge topics like Agentic Development, Vibe Coding, and workflow automation. Bringing this to Spryker resulted in higher efficiency and quicker improvements, lowering our TCO."
