Few people have ever heard of Prevas Bioinformatics, and that doesn’t really bother CEO Jonas Wiström. Although public, his company is traded on the Stockholm exchange, not Wall Street. And while the company’s website lists 10 bioinformatics customers, Prevas concentrates on Nordic companies. Wiström’s logic: in this precarious market, it’s better to be safe than sorry. “We are a very old-fashioned company in terms of being careful and protecting our profits,” he says.
