Stories about and results of 8-i (8 Hours Overtimes in a Good Cause International) throughout the years. 

Dear 8 Hours' Overtime for a Good Cause 2014 enthusiasts, thanks so much and enjoy Friday night!

Erwin Elling

Next Friday, 8 Hours' Overtime for a Good Cause will take place in (at least) 16 cities on 3 continents. In Rio de Janeiro, Tilburg, Leeuwarden, San Fransisco, Leiden, Delft, Groningen, Brasov, Tomar, Portalegre, Utrecht, Bucharest, Amersfoort, The Hague, 's-Hertogenbosch and Nijmegen people will donate 8 hours of their time to help out local causes.

This crowd will use their combined creativity to solve real challenges, share their skills (and learn some new ones), meet new friends and enjoy a great night. The whole event is organized bottom-up by local volunteers, without a budget (at least not a monetary budget) and might differ in every city, to suit the local context. 

What's the same in every participating city though, is that this event would not be possible without the hard (voluntary) work of many many people. All of you, thanks so much and have a great night!

If you are one of the participants: These'll be some of the best hours of overtime you've ever had :) Go work your *ss off for a local cause and have lots of fun doing so!

If you are a representative of a good cause: It's very rare that you can be part of a group of people working this hard just for you! Enjoy the end results as well as the incredible process!

If you are one of the organizers: This is what you've worked so hard for. The event wouldn't have taken place without your efforts. Now it's time for you to sit back and enjoy the magic!

If you are one of the sponsors: It's incredible what can be achieved if everyone pitches in a little of what they have plenty of. Thanks so much for your donations in time, goods, ideas, network, ...!

If you are none of the above: Keep an eye out for #8i2014 on your favorite social networks and for future reports on this blog. There will be tweets, pictures, videos, livestreams, etcetera covering the night. I bet you'll want to be part of this next year!

(8 Hours' Overtime for a Good Cause 2015 will take place on 27 March 2015 ;))

What 8i was like in 2013 in Groningen

Erwin Elling

It can be quite hard to grasp what 8 Hours' Overtime for a Good Cause is really like. 8i is different in every city and every year. We asked co-organizer Mark Meinema to describe his experience with '8 uur overwerken voor het goede doel' in Groningen (The Netherlands) in 2013:

"For me, 8i2013 was stunning evidence that a fantastic event can be organized in very little time (most of the work was done in less than a month!), as long as you’re surrounded by some truly fantastic people.

And it only got better because of the fabulous creative teams. I can still hardly believe that 8i generates so much energy in just one night. But most importantly, we made some products for the good cause organizations that really rocked!"

You can see what the night was like in this video by Giordano Nunes:

What 8i was like in 2013 in Rio de Janeiro

Erwin Elling

It can be quite hard to grasp what 8 Hours' Overtime for a Good Cause is. Even if you read or talk a lot about it. The event is different in every city and different every year. We asked co-organizer Marcio Gonçalves to describe his experience with '8 horas extras por uma boa causa' in Rio de Janeiro last year:

"When my friend Monica Alvarenga invited me to participate, I was thankful for the opportunity. On the day it happened, I was really surprised with the great atmosphere of donation among all participants. On that day I have learned the real meaning of giving and receiving. We had 8 extra hours of great pleasure."


What 8i was like in 2013 in Utrecht

It can be quite hard to grasp what 8 Hours' Overtime for a Good Cause is. Even if you read or talk a lot about it. The event is different in every city and different every year. It's one of those things you should really just experience.

Still, it would be nice to give you at least some idea of what 8i could be like. Take a look at this video registration of '8 Uur Overwerken voor het Goede Doel' in Utrecht, The Netherlands in 2013:

Some pre 2011 results

Erwin Elling

To give you an idea about the result, here are some results from earlier editions:

In Groningen in 2007 a tiny charity called Rahan Yam-Tel joined. They didn't have any visual identity nor written communication about their goals etc. The team of 6 creatives took the challenge and designed a logo, website, stationary and wrote all text in two languages for their site and fundraising letter. The result still stands after four years.

A couple of years earlier Bartiméus set a challenge, they had rented airtime for a radiocommercial for the saturday after 8uo. And a team led by Renger Koning met that challenge and produced a professional commercial that was used for the campain. Check out the Bartimeus Commercial.

Other organisations that have been helped in the past are: the Dutch chapter of Médecins Sans FrontièresGreenpeace (the team helped out with a campain that was still in development back then about e-waste) and local subsidiaries of the International Red Cross for example in Apeldoorn in 2011. A more complete list can be found on the Dutch website.
