This page provides basic information for event organisers who want to invite me to speak at their event.

Keynotes, workshops, facilitation

I’m an experienced presenter and group facilitator. Over the years I have given many keynote talks, presentations and fully participatory workshops in Europe, North America, Central and South East Asia. I’m comfortable in front of small audiences, and in front of several thousands. See TalksandVideos for an overview of the last few years.

Topics, grounded in my own experience

Topics I enjoy presenting on include data governance, open government, open data, networked agency, digital disruption, digital transformation, ethics by design, and digital making. I usually combine material from my own professional practical experience with insights and sensemaking on a higher and broader level of understanding.

Stories tailored to you, in three languages

All my presentations are tailored to the audience and event I’m invited to. Although material and observations may be re-used regularly, and key messages are always consistent, the story arc is always specific to the occasion. I am fluent in English, German and Dutch. I’m also comfortable working with simultaneous translators.

Full attention for your event

I always take an active stance at the conferences I contribute to, out of curiosity in the audience’s experience and their questions, passions and going concerns. By engaging in conversations with event participants and being approachable, by being active on the social media back channels of your event, and by being available for press or sponsor meetings. In short I am as much a participant as anybody else attending the event. It also means I normally try to take part in the entire event, and whenever possible avoid attending for just my slot on the program.

I’m an event organiser myself

As an invited speaker I will aim to avoid causing you hassle, and will take my responsibilities to your event serious.
Over the years I have organised many events myself. International conferences in different countries, a multi-year long series of international workshops across 3 continents, community and fringe events in parallel to global conferences, all varieties of workshops, and with my wife I repeatedly organise international indie-conferences for our birthday party. I’ve organised events with large budgets and with no budget at all. In short, I get it.

Rights, slides, videos

I retain all rights to my presentations and will publish them myself online with a Creative Commons BY-(NC)-SA license. You are welcome to publish and distribute my slides within those license conditions. You are always allowed to record and/or stream my presentation.


Please approach me as early before your event as possible (generally at least 2 months in advance is excellent, less than 3 weeks in advance likely means I’m not available). It would be great if you can send an e-mail first that explains how you would like me to contribute to making your event great, and providing links to general information, program ,and / or history of the event. Let’s talk to eachother in person after that first e-mail, to explore how we can work together. This also allows your team and me to make my presentation fit your event and audience.

Should I not be available on the date of your event, I will try to suggest other speakers to you.

Speaking fees, travel costs

As a self-employed professional I charge fees for speaking. The costs of international travel and lodging are not covered by the speaking fee and should always be covered in addition. My speaking fee is 3150,- Euro excluding VAT if applicable, for a keynote of up to 45 minutes or a panel or working session up to 90 minutes. It can be higher, based on mutual agreement, if the requested contribution is larger or requires more preparation than usual. It can be lower as well.

My speaking fee will be lowered for low income countries (to 1900 Euro) and middle income countries (to 2500 Euro).

If you organise a free event or a non-commercial event, the fee may become negotiable or may be waived (but not international travel costs). Over the last 15 years I have contributed to many free conferences, unconferences and BarCamps for free, because the theme, the audience or my own learning agenda was a good fit. If you would like me to waive my speaking fee, please provide reasons why I might do so in your first e-mail (saying it will be great exposure for me is not a valid reason), and let’s discuss. In other words: don’t be discouraged to approach me.

Logistics, practicalities

I will expect to be able to use my own laptop to present (because of speaking notes and monitor functionality), and will bring the needed adapters.

Usually I will finalise my slides at and during your event (unless I’m the opening speaker), and adjust some of the messages, wording and examples based on hearing participants and other speakers, and the general atmosphere of your event. This means that other than a basic outline I will not be likely to provide my slides before your event. When working with (simultaneous) translators, I will try to provide speaking notes or an outline upfront for the translators.

Bio, photos

Please find shorter and longer descriptions in English, German and Dutch, as well as photos for you to use on the page BiosandPics. I may propose to change the bio to emphasise aspects more relevant to your event.


Ethics by design is adding ethical choices and values to a design process as non-functional requirements, that then are turned into functional specifications.

E.g. when you want to count the size of a group of people by taking a picture of them, adding the value of safeguarding privacy into the requirements might mean the picture will be intentionally made grainy by a camera. A more grainy pic still allows you to count the number of people in the photo, but you never captured and stored their actual faces.

When it comes to data governance and machine learning Europe’s stance towards safeguarding civic rights and enlightenment values is a unique perspective to take in a geopolitical context. Data is a very valuable resource. In the US large corporations and intelligence services have created enormous data lakes, without much restraints, resulting in a tremendous power asymmetry, and an objectification of the individual. This is surveillance capitalism.
China, and others like Russia, have created or are creating large national data spaces in which the individual is made fully transparent and described by connecting most if not all data sources and make them accessible to government, and where resulting data patterns have direct consequences for citizens. This is data driven authoritarian rule.
Europe cannot compete with either of those two models, but can provide a competing perspective on data usage by creating a path of responsible innovation in which all data is as much combined and connected as elsewhere in the world, yet with values and ethical boundaries designed into its core. With the GDPR the EU is already setting a new de-facto global standard, and doing more along similar lines, not just in terms of regulations, but also in terms of infrastructure (Estonia’s X-road for instance) is the opportunity Europe has.

Networked Agency building blocks

This is my take on agency, which is a networked agency. I formulated it in 2016 as a way to express what unifies all my work, basically since I started working.

In our digital, globally networked and hence more complex age, we need a qualitatively different approach to agency.

This means embracing the affordances digitisation and networks give us.
This means designing our digital tools fully aligned with the core ideas behind interconnected networks (smart at the edges and within control of its users, can work alone yet (much better) locally or preferably globally connected).
This means taking complexity as a given, where experiences, probing, and responding to things play a key role.

This makes an individual including its meaningful relations to others, in a specific and real life context the relevant unit of agency.
This is networked agency.

Networked Agency, residing at the level of an individual plus its social context, I see consisting of three parts:

  • Striking power. The ability to (collectively) act and create on your own accord. This is where low-threshold tools are important, as is knowledge of working methods and processes.
  • Resilience. The ability to shield oneself against and mitigate negative consequences of other’s behaviour propagating through the network to you. This is where being able to work locally when disconnected is important, and temporarily suspending interdependencies. Next to early warning systems, and how to help put a brake on negative patterns you identify.
  • Agility. The ability to leverage, adapt and respond to opportunities from other’s behaviour propagating through the network to you. This means sensing what is going on early, seeing what aligns with the interests and needs of the local network, how to use that for yourself, and how to feed attractive patterns with ones own contributions to help sustain them. (e.g. open source development).

As an example of a design aid, I created the image below:


Early 2017, in collaboration with the Frisian Library Service, we used the above to design a project with a primary school group, for them to design and create ‘solutions’ to things they wanted to change in their environment. The feedback was very positive, both from the participants, my project partners and the financing Dutch Royal Library. It turned into the basic working method of the Frisian Library Service, and we’re currently trying to extend that collaboration also with other local libraries in Europe.

Keynote video

At the June 2018 State of the Net conference in Trieste I gave a keynote on networked agency. A video, alongside my slides, is available.

This is the frontpage of my emerging wiki-like collection of semi-permanent content. Where blogposts form a ‘river’ of items, for reference it is useful to have a range of more static ‘pools’ of content. Both to provide additional context and background to blogposts, as well as a useful documentation in itself. Documentation of ongoing work, reading, research, or experiments. (April 2018).
