Trisha Prabhu is a 24-year-old innovator, social entrepreneur, global advocate, and inventor of ReThink™, a patented technology that proactively detects and stops online hate at the source, before the damage is done™. In the fall of 2013, Trisha, then just 13 years old, read the shocking news story of a 12-year old that died by suicide after being cyberbullied for over a year-and-a-half. Having had own experience with bullying and cyberbullying, Trisha was heartbroken and outraged. She knew that she could not be a bystander to the silent pandemic of online hate; she had to be an Upstander.

In response, Trisha designed and developed the patented technology ReThink™, which detects online hate before it is sent and prompts the sender to pause, review, and rethink ("Are you sure you want to say that?"). At just 13, Trisha conducted a science experiment testing ReThink's efficacy. Her globally acclaimed research found that over 93% of the time, youth aged 13-18 that received a chance to rethink changed their mind.

Trisha later founded the ReThink social enterprise, a global movement with the mission of tackling cyberbullying and redefining internet culture to be more kind and inclusive. Today, ReThink’s technology (named one of Google Play’s Most Innovative Apps), educational materials, and anti-cyberbullying advocacy have been shared with youth worldwide. Trisha is also the Founder and President of ReThink's non-profit arm, ReThink Citizens, which has brought ReThink's offerings to thousands of historically underserved youth across the US and and is building a pipeline of young digital changemakers that are working to create the internet that they deserve.

Trisha has received worldwide acclaim for her entrepreneurial efforts. In 2016, then-President Obama and the U.S. State Department invited Trisha to the Global Entrepreneurship Summit at Stanford University, to showcase her work and share her story with other entrepreneurs. Not long after, ReThink was featured on ABC's hit T.V. show, Shark Tank. In 2019, ReThink was named the Grand Prize Winner of Harvard University's President's Innovation Challenge. And in 2020, Trisha was named one of the inaugural winners of the prestigious Elevate Prize. She was also named a Harvard Kennedy School Adrian Cheng Fellow. In 2021, she was the youngest honoree named to Forbes' 30 Under 30 Social Impact list.

Trisha has also been honored with awards and recognition for her ingenuity in inventing and building ReThink. For her research and scientific inquiry, Trisha was named a 2014 Google Science Global Finalist. In 2015, she had the honor of showcasing and sharing the ReThink at the 2015 White House Science Fair, at the invitation of President Obama. In 2016, she was awarded the 2016 MIT INSPIRE Aristotle Award.

For her anti-hate advocacy and activism, Trisha has received the WebMD Health Hero of the Year Prodigy Award, the Princess Diana International Anti-Bullying Award, the Global Anti-Bullying Hero Award from Auburn University, the Upstander Legacy Celebration Award from the Tyler Clementi Foundation, and the Daily Points of Light Honor from the George H.W. Bush Foundation. Most recently, in 2023, Trisha was the recipient of Mozilla's Rise25 Award, which celebrated Trisha as one of 25 digital changemakers shaping the future of the internet.

ReThink Citizens, too, has received much acclaim. The organization is a two-time Responsible Technology Youth Power Fund grantee and, in 2023, was named an inaugural Young Futures fund grantee. ReThink Citizens has also been publicly celebrated by Prince Harry and Meghan, the Duke and Duchess of Sussex.

Her TED talk, "Rethink to stop cyberbullying," was celebrated by Indian celebrity Shah Rukh Khan and shared on Start TV with 650 million Indian views. Her TEDxTeen talk, "ReThink before you type," has been viewed over 1 million times on YouTube. Trisha has also spoken on several other TEDx stages, at the Aspen Ideas Festival, the Responsible Digital Future Summit, alongside Prince Harry and Meghan, the Duke and Duchess of Sussex, La Ciudad de Las Ideas, the Family Online Safety Institute, universities, schools, and more.

Trisha currently serves on the Council for Responsible Social Media, where she supports the Council's work to advocate for an information environment that is safer for youth. She also serves on the Responsible Technology Youth Power Fund's Steering Committee.

When she's not being a girl boss, Trisha volunteers her time to efforts to empower womxn in the technology and entrepreneurial worlds. She is a former Girls Who Code teacher and formerly led SoGal Boston, a chapter of the SoGal movement, which is committed to ending the diversity gap in entrepreneurship.

Trisha received her BA summa cum laude and Phi Beta Kappa from Harvard College. She received a Master of Science and MPP at the University of Oxford, both with Distinction, as a US Rhodes Scholar.
