Barely six months after it raised an $18 million third round, video ad provider Tremor Media has secured additional funding, the company announced. According to an SEC filing, the company raised nearly $2 million to the round, which comes on top of what Tremor received from Meritch Capital Partners, Canaan Partners, Masthead Venture Partners and European Founders Fund last time out. The added funds is from SAP Ventures, the investment arm of the business software company. The deal represents the start of a planned collaboration to sell media firms in the U.S. and Europe on the two companies’ products and services. New York-based Tremor plans to use the funding for additional product rollouts. This past summer, it came out with its vChoice suite of ad formats powered by its Acudeo technology. Release
