The Technovation Challenge is a free, worldwide, technology entrepreneurship competition in which each teams of up to five girls (in three divisions by age:  8-12, 13-15, 16-18 years old) identify problems in their local communities, build prototype applications for them (AI or mobile apps), develop business plans, and pitch the plans to potential investors. Teams meet January-April for 3-4 hours weekly with mentors from the tech/business community in preparation for regional and worldwide events in May and June. Sign up here. The MassTLC Education Foundation, which hosts the program in the Boston area, seeks volunteer mentors with expertise in coding, design, marketing, or finance.
