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.
"Pick us, because we're built in the EU!" 🇪🇺
Then:
🚩 still the same bad BigTech practices
🚩 centralized, walled-garden structures
🚩 "invite only" silicon valley growth tricks, not a real limit
🚩 some make you send in your ID or passport first (RUN!)
🚩 if they go down, your data still goes with them
@flo-bit.dev hey, would you be interested discussing adding some Sifa sources to @blento.app ?
Think it would be neat and useful if people can build/show their CV on blento pages, drag/drop the sections they want, or maybe a simple card that shows their current employer, current work status etc.
If you are a "non-profit founder" (e.g. @cjkarr.bsky.social)...
Does that mean you've founded a non-profit company...
... or that the company you have founded didn't manage to turn a profit (yet). 🤔
If it's the latter I should maybe put "non-profit founder" on by business card as well? 😅
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."
"His strategic thinking impressed me. Guido understood that communities need sustainable business value, not just engagement metrics. The hackathon projects directly influenced what we built next, including some AI features."
"From the very first moment, he welcomed me with his enthusiasm and passion for e-commerce, community, and the Spryker product."
"He is a brilliant presenter, a natural connector, and a trusted advisor who understands both the human and business dimensions of digital commerce. His empathy, humor, and communication skills make him uniquely effective at engaging with people on every level, from developers to executives."
