Outcome management platform Grand Rounds has secured $40 million in Series B funding led by Greylock Partners. The new round, which also includes participation from existing investors Venrock and Harrison Metal Capital, brings the company's total to-date funding to about $51 million. Grand Rounds helps patients receive medical guidance from the top physicians in the nation as selected by its scoring algorithm, which determines top medical specialists based on a range of factors including training, publication history and patient outcomes. The company will use the proceeds to increase R&D to enhance its quality scoring algorithm, accelerate sales and marketing, expand upon its mobile capabilities and build out its infrastructure. Grand Rounds last raised $10 million of Series A funding (led by Venrock) at a $38 million valuation in May 2013.
