Diana Hall has invented a better cast (the type your doctor gives you when you break a bone). After running a mentoring program for children from low income families, Diana saw how traditional plaster casts weren’t cutting it. They couldn’t be cleaned. They made it hard to see infections. And they were unnecessarily bulky. She knew there had to be a better way.

That was the inspiration for ActivArmor. Today, ActivArmor offers 3D casts and splints that empower patients to maintain active, hygienic lifestyles. The company uses a simple iPhone scan to design custom casts, and the results are breathable, waterproof, and sanitizable.

In this episode of Inside Startup Investing, Diana tells Chris Lustrino how her company is making the production of these next-gen casts even easier. The two also discuss how ActivArmor is ensuring that clinics benefit from adopting this technology, the health benefits of being able to shower with a cast, and the company’s strategy for achieving mass adoption.
