"Guido is a thought leader in community building and developer relations. Any company serious about building an ecosystem should talk to him."
I build community functions for tech products.
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.

Hey everyone, time for you to put in the comments of the post below on why @thegoodlobby.wsocial.eu (or anyone really...) should not register on /move their accounts to W Social (and rather pick a better alternative like @eurosky.social, or even just self-host if they want to be independent) 👇👇👇

@popfeed.social could you make the directors name clickable (just like actor names) so you get to a page with all the work from this director?

Asked Claude to write my apology text and it suggested 'I acknowledge your feelings and will strive to do better.' Looks like I'm sleeping on the couch tonight

@popfeed.social could a setting be created to exclude already watch materials on pages like /find and in the recommendations block on movie/tv series? I love getting the recommendations, but don't need to see mostly things I've already marked as watched :)

Brands I've worked with
From retail to telecom to financial services, I've helped teams across industries build stronger communities.
Writing
Talks & speaking
that's me Why this approach works
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.
Guido has a rare ability to translate community insights into tangible business intelligence, and to bring the business closer to the community.
Projects
Portable professional identity on AT Protocol. A track record built from real community contributions.
Open-source community forums where members own their data. Log in with Bluesky; reputation follows you.
200+ conversations on growth, experimentation & optimization. One of the longest-running CRO podcasts.
Training
Agentic Engineering
co-led with ExecuroStop typing better prompts. Start delegating to AI agents that ship.
- Delegate to AI agents with clear specs, context and rules instead of better prompts
- Build a complete app together: frontend, backend and API, hands-on
- Walk away with reusable agentic workflows and AI coding rulesets you keep
Intro to Building on AT Protocol
Open social tech for developers
- What AT Protocol actually is, and why it matters for your product
- Set up a PDS, create records, wire a simple Bluesky client
- How communities on open networks are different (and why that's an advantage)
