Mizu, the American brand of reusable bottles, has hired two new executives while it is introducing a new water filtration and purification category. Craig Smith, who has been most recently the European sales and marketing manager of Dragon, will serve as European sales and marketing manager of Mizu Europe. Scott Keating, former global sales director of Nike SB, will be Mizu's new vice president of sales and marketing. The company set up its European subsidiary near Amsterdam two years ago.
