Plek in space
Place works well for staffing agencies. Makes sense, because you need to engage and inform all the people working at clients' offices. Plek is being used by for example IT people (CRI), financial and HR professionals (Verhoeve) and manufacturing and middle management (STAN / PDZ).
But secretly ATG Europe is our favorite, because they staff real rocket scientists at organizations such as the European Space Agency. In addition, they do great projects such as Outernet: a network of microsatellites the size of a milk carton to bring the Internet to billions of people within reach.
And they gave us a new slogan too: "You do not have to be a rocket scientist to use Spot - but they do anyway."
