Selina Tobaccowala was working at SurveyMonkey when her mentor and good friend, CEO Dave Goldberg, passed away. His sudden death put her life in perspective. Tobaccowala herself was working endless hours and leaving little time for her health. Now, the entrepreneur has launched Gixo.

Tobaccowala joins Cheddar to explain her new app. The fitness platform effectively turns a user's smartphone into a mobile gym. Gixo offers 180 live fitness classes, and costs $24.99 a month for the unlimited option. Tobaccowala could see that U.S. consumers, and millennials in particular, are interested in interactive, experiential workouts. Tobaccowala and her co-founder, Al Lieb, wanted to create an option for that consumer that didn't cost as much as a traditional gym membership or a boutique fitness class.

Gixo classes are primarily conducted with audio, and users can sync their wearables to the app. Because the classes are live, coaches can give feedback to the user after the class.
