San Diego-based healthcare administration technology provider Benchmark Revenue Management said today it has raised additional capital in what it called a Series A funding round that was led by David Barach of the Tech Coast Angels. CEO Tyson McDowell says the round will enable the company to achieve positive cash flow, but he declined to disclose the amount. In March McDowell put the company onstage as a case study at the San Diego MIT Enterprise Forum, where experts advised him to hang on and grow the company. The cash infusion follows an earlier investment round led by San Diego-based Express Ventures and “additional capital from Benchmark founders, friends, and family.”
