EchoMark, a Seattle-area startup led by former Microsoft VP Troy Batterberry, raised $10 million in seed funding to develop digital watermarking technology that helps organizations identify document and email leakers. The technology uses visible and invisible watermarks, including subtle text alterations, to make documents uniquely traceable and support leak forensics.
