Kleiner Perkins is leading the round for Brex. : Brex, the fintech business that’s taken the startup world by storm with its sought after corporate card tailored for entrepreneurs, is raising millions in Series D funding less than a year after it launched, TechCrunch has learned. Bloomberg reports Brex is raising at a $2 billion valuation, though sources tell TechCrunch the company is still in negotiations with both new and existing investors. In response to a request for comment, Brex co-founder and chief executive officer Henrique Dubugras told TechCrunch they have no news to announce at this time.
