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.
atproto'd my website a bit further (beyond the @standard.site integration):
1) added a "Right now" box on the homage that pulls in all kinds of atproto activity like @bsky.app posts, @popfeed.social film ratings, @bookhive.buzz reads, @tangled.org repo's etc.
well, if you were still having doubts about W Social, this will probably seal the deal (and not in a good way..)
Investigation 🧵 by @thisismissem.social 👇
Interesting quote on the @bsky.app homepage from Matt Mullenweg.
He's right.
He's also proof of why it matters: when one steward owns the infrastructure, "open" lasts exactly as long as his goodwill.
Ask @wpengine.com
On a protocol, you don't have to trust the steward.
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.

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."
"Guido consistently brought energy and openness, making it easy to connect on both professional topics and personal interests like AI and podcasting. He also excelled at connecting people across business and technology, turning community exchanges into actionable collaboration. Guido showed real leadership without ever being my manager, creating alignment and momentum simply by bringing people together."
"Conversion rate optimization, psychology, leadership, and business are just a few of the topics he's spoken to at the highest level."
