Technically yes, ReThink is still active, though its momentum has clearly slowed. The anti-cyberbullying app, which prompts users to reconsider hurtful messages before posting them, is still available in app stores but shows limited recent activity.
What happened on Shark Tank
Teen founder Trisha Prabhu pitched ReThink on Season 8 and appeared to reach an agreement with Mark Cuban and Lori Greiner. Something derailed that arrangement afterward, and the deal did not go through as discussed on air.
What happened instead
Rather than depending on Shark Tank funding, Prabhu found an alternate path. In 2020, while still a student at Harvard, she secured a $300,000 grant from the Elevate Prize Foundation to further develop the app. In 2022, she published a book, ReThink the Internet, with Penguin Random House, expanding her platform around making the internet safer for younger users beyond the app itself.
Current app status
ReThink remains listed on both the Google Play Store and the Apple App Store. The Android version shows an update as recently as October 2025, while the iOS listing hasn’t been updated since 2023, a sign of app activity without strong current momentum.
