"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.

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.

IDK why everyone keeps calling it vibe-coding. Running out of my 5h limit completely kills the vibe each and every time

inspired by @dame.is & @brookie.blog, I set myself up with a nice little dynamic profile picture automation, updating the image (or rather: the background/accessories) based on season / weather / country / holiday. Overkill? Ooooh yes very much so. Confusing? Potentially. Fun? ... I hope so!

PSA: if you self-host your PDS and experience (re)login issues with atproto apps: install PDS version 0.5.4, this includes the fix for the issue (which is described below)

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'm doing 'Angry Yoga' tonight. It's just lying on my Aeris Muvmat and drinking whiskey as I shout commands at Claude.

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)
