Katie Warner Johnson and Caroline Gogolak are the cofounders of Carbon38, a website that aims to empower strong women to lead active lives. Preparing for an early 2013 launch, Carbon38 is an online platform that captures the intersection of fitness culture, community and commerce. Katie and Caroline started out as ballerinas together at the Miami City Ballet, studied in Adams Dining Hall as undergrads at Harvard and now thirteen years later are starting a business. With backgrounds in fitness and finance and a mutual love of lululemon, road bikes and endorphin spikes, Katie and Caroline hope to give fitness a makeover. Stay tuned for updates.
