to get a glimpse of what this conference is all about!

For the 6th year in a row the Online Optimizers Meetup Group (derived from the community) will organize, again with great help of Online Dialogue, this acclaimed 3 days conference for people with a growth mindset.

Secluded on the beautiful island of Texel in the Netherlands, passionate digital optimizers share their knowledge, experiences and skills in the field of Product, UX, Marketing, Data and Design. Like the past years we expect attendees from Europe, North America, Asia and even Australia.

  • Hello: Friday November 22nd 2019 (13:00 CET – hotel check-in)
  • Goodbye: Sunday November 24th 2019 (13:00 CET – event ends)

After scaling up in celebration of our 5th anniversary last year, this year’s event will be more intimate (limited to 240 attendees), creating more opportunity for in depth interaction with fellow attendees – learn and teach.

On behalf of the #CH2019 team,
Nienke van der Sar, Eddy Morreau and Ton Wesseling

How to get to the conference?

Route to Texel

Texel is an island, so you have to take the boat (with or without your car). The boat leaves from Den Helder. All ferry times and rates can be found at: If you take your car on the ferry (like most people do): the main conference hotel has free parking space!

I arrived at Texel without a car!

When you arrive at Texel, you can take a cab to the hotel or bus 28 and leave the bus at the stop called ‘Dorpsstraat’ in ‘De Koog’ (which is nearby the conference hotel(s)).

Route from airport

If you arrive at Amsterdam airport, you’ll need to take the train to Den Helder. From there you have to take the ferry to Texel. See “route to Texel” and “I arrived at Texel without a car!”.
