Indianapolis--Aprimo Inc. said Wednesday that it has added $20 million in venture capital to its corporate coffers through a third round of funding led by First Analysis Venture Capital, Sigma Partners and Frazier Technology Ventures. The funds will be used to expand Aprimo's sales and professional services ranks. Aprimo, which launched operations last year, provides Internet services for managing a corporate marketing department. It allows marketing executives at large companies to delegate responsibility for marketing projects throughout a company, and track in real time the progress of those projects. The Indianapolis-based company has raised $34 million to date, and its next step will likely be an initial public offering. Customers already using Aprimo include Afilent, Tektronix and Burger King.
