Sequel Medtech is working to sell a new, more precise type of insulin pump that can measure the amount of insulin delivered to users. 

CEO Alan Lotvin, former president of pharmacy benefit manager CVS Caremark, started the company in 2023, along with Dean Kamen, president of Deka Research and Development, and three other co-founders. 

Kamen created one of the first portable insulin pumps in the ’70s and is also known for another invention — the Segway. Deka developed the new insulin pump, called Twiist, and received Food and Drug Administration clearance in March for the device to be used by people with Type 1 diabetes. Sequel will market the device.
