Tandem Diabetes designs, manufactures, and markets durable insulin pumps for individuals with diabetes. The firm first entered this market in 2012 and has since introduced multiple generations of pumps leading to its current t:slim X2 device. The firm recently launched its smaller Mobi pump and continues to work on the Sigi tubeless patch pump. Tandem is also developing a fully closed-loop algorithm for its pumps. Nearly three-quarters of total revenue is derived from the US, with the remainder primarily from other developed nations. The pumps themselves generate just over half of total sales, and another one-third is from disposable infusion sets that need to be changed over every 3 to 7 days.
