It is very likely that the deal with Mark and Lori did not close as neither Shark lists the company in their Shark Tank portfolios.

Since appearing on Shark Tank, ReThink has reached 56,000+ downloads through Google Play where it has a 3.5 star rating. It is also currently available in the App Store where it holds a 3.2 out of 5 star rating.

User reviews applaud the app for its effectiveness in changing bad thought habits. Most complaints and issues stem from the apps technical issues which are still in the process of being resolved.

Future plans for the app include in-app purchases for parents and availability in a wider range of languages. ReThink is currently available in English, Spanish and Hindi.

Although ReThink’s growth has been stagnant for a while now, the young entrepreneur has been making waves in various areas, using her voice as an advocate for female entrepreneurship, financial literacy and more notably, against cyberbullying.

Through ReThink, Trisha has spearheaded community action against cyberbullying by expanding the ReThink movement through various chapters in schools across the country. Her efforts have not gone unnoticed.

In 2016, Trisha was honored as a Health Hero by WebMD and in 2017 presented a talk on cyberbullying at TED Talks India. More recently, ReThink was awarded at the Innovation Challenge sponsored by Harvard’s Technology and Entrepreneurship Center.
