Madison, Wisconsin-based Echometrix expects to offer EchoSoft, software to improve ultrasound diagnosis and management of tendon and ligament injuries, by year’s end, according to CEO Sam Adams. Last week, the four-year-old startup filed Securities & Exchange Commission documents seeking to raise $1 million toward that goal. Adams said in a phone interview that most of the money would pay for product engineering, regulatory work, clinical studies, marketing and business development.
