I was quite astonished when reading about their insane growth. Most of the companies we talk to in The Netherlands (Telco's, E-commerce, Banking / insurance, travel) are using VWO, Sitespect and last week I heard two clients talk about Maxymiser. Not one time I heard them talk about Optimizely. Seems there is still a lot of room for growth (at least in NL).
We (usabilla.com) are using Optimizely with great satisfaction though!
We're thrilled to have opened our first international office in Amsterdam! We have a phenomenal team of sales and support folks who speak many of the languages out there. Our hope is to delight our European customers as much as we've delighted customers back here in the U.S.
