For 37 Signals it doesn't have to scale any time soon, but the grandfather was (tacitly) in reference to how many look to 37 Signals as exemplars of how to run small to medium tech businesses (why else write about it in Inc?) I think if I already had a business of 10-15 people this would be a good model to attempt to follow. If I had a business of 40+, I would be far more wary; the question of scale is for those who may try to fit the model to their existing business.
