Wello, a fitness platform, is using Twilio's SMS service to offer personalized workouts via video chat with trainers, friends, and family. The company was founded in 2011 by Ann Scott and her partner Leslie after they found traditional gym options inconvenient and expensive. Wello has seen significant user success, with clients completing over 80 workouts and losing hundreds of pounds. The platform is expanding its services to include group workouts and a potential iPad app, aiming to make fitness more accessible and convenient for users. With Twilio's SMS service, trainers can receive booking notifications and confirmation codes, streamlining the workout experience.
