Frankel is the founder of BStrong, a disaster relief organization. In 2017, the organization raised $300,000 in donations and supplies for the victims of Hurricane Harvey, after which Frankel visited Houston, Texas to distribute these items. In the same year, Frankel traveled to Mexico City and Jojutla, Mexico following the Puebla earthquake to raise awareness for the disaster's recovery efforts, for which BStrong also raised $150,000. Also in the same year, Frankel chartered four planes to Puerto Rico and distributed medical supplies, food, water, and hygiene products in assisting with Hurricane Maria relief efforts. In light of the COVID-19 pandemic, BStrong raised funds and delivered personal protective equipment such as masks, goggles, gowns, and sheets to hospitals in the U.S.
