Detroit--Covisint L.L.C., the Big 3 automakers' storied e-hub is to launch Covisint Europe within the next few days, according to the Financial Times Deutschland. The European unit will be based in Amsterdam and its chairman will be Lars Olrik, a former Ernst & Young L.L.P. executive, according to the report. Stateside, parent Covisint is still searching for a CEO, though it is already operating. The launch underscores how b-to-b exchanges are increasingly setting their sites on Europe as an offset to the slowing U.S. marketplace.
