Vantos, a Seattle-based software startup with a product that can help companies with internal investigations and auditing, has raised $10.6 in a second round of funding. Regulatory changes like the passage of Sarbanes-Oxley have opened the way for companies like Vantos. New laws demanding tight controls and tracking of issues can cost public companies millions. While there's no way to avoid some cost, specialized software can help accountants, lawyers and managers learn how to navigate the regulations, and streamline that process. The $10.6 million funding was led by Fluke Venture Partners, with participation from OVP Venture Partners and Outlook Ventures.
