Big data has been given a new boost this week as Apixio secures $13.5m from Bain & Co. in its series C funding. The data analytics start-up makes sense of stray data from multiple databases that are hidden in doctor’s notes and scanned documents – part of the new movement to help healthcare providers efficiently (and more accurately) predict patient risk. The hope is that it leads to better billing. The fresh capital brings the San Mateo-based start-up’s total investment level to $22.6m. Founded in 2009, Apixio have previously been seeing more interest from angel investors than venture capitalists.
