A teenager walked into Shark Tank with an app designed to stop cyberbullying before it starts — not after. That teenager was Trisha Prabhu, and her product, ReThink, caught a lot of attention. But what actually happened after the cameras stopped rolling?
This article covers the key things people want to know: how the app works, what happened during the pitch, whether the Shark Tank deal actually closed, and whether ReThink is still around today.
What ReThink Is and How the App Works
ReThink is an anti-cyberbullying app and software tool. Its job is simple: scan text for potentially harmful language before a message is sent.
When the app detects something hurtful, it stops the moment and asks the user to pause. Think of it as a “pause button” for impulsive messages. The user gets a prompt asking whether they really want to send what they typed.
That might sound small, but the idea behind it is significant. Most cyberbullying tools work after the damage is done. Someone posts something cruel, it gets reported, and then maybe it gets removed. ReThink tries to stop the message before it ever goes out.
Here is a simple example: a teenager types a mean comment on social media. Before they hit send, ReThink interrupts with a prompt. That one pause is the whole product.
The app uses a patented algorithm to identify hurtful language. It is not just flagging swear words — it is looking for phrases and patterns that tend to cause harm. The approach is preventive by design, which makes it different from almost every other tool in this space.
Who Founded ReThink and Why
Trisha Prabhu created ReThink as a teenager. After learning about the real impact cyberbullying was having on young people, she wanted to do something about it — specifically, she wanted to address the problem at the source.
Her core insight was practical: most hurtful messages are sent in the heat of the moment. If you could interrupt that moment, you might prevent the message from being sent at all. That idea became the foundation of the product.
Prabhu went on to serve as founder and CEO of the company. Her background was not in tech — she was a student with a problem she wanted to solve. That origin story is part of what made ReThink stand out, both on Shark Tank and in the press.
The Shark Tank Pitch and What the Sharks Said
ReThink appeared on Shark Tank Season 8, Episode 1. Prabhu presented the product as a technology tool aimed at reducing online bullying among adolescents.
The pitch combined a clear social mission with a working tech product. That combination tends to generate strong interest from the Sharks, because it gives them both a business angle and a story they can get behind publicly.
During the episode, a deal was discussed and appeared to be accepted on camera. Viewers watching the episode likely came away thinking a Shark had invested in ReThink.
But that is where the story gets more complicated.
Did the Shark Tank Deal Actually Close?
This is the question most people are searching for, and the honest answer is: the deal reportedly did not officially close after filming.
This is more common than most people realize. Shark Tank deals made on camera go through a due diligence process after production ends. That process sometimes surfaces issues that cause deals to fall apart before money changes hands. The deal may look done on TV, but the paperwork tells a different story.
In ReThink’s case, later reporting indicates the deal never officially closed. The specific reasons are not fully detailed in available sources, so it would not be fair to speculate about why it fell through.
What matters for readers is this: if you watched the episode and assumed a Shark invested, that assumption may not be accurate. The deal that appeared on screen did not appear to result in a confirmed investment.
Is ReThink Still Active Today?
Yes, ReThink appears to still be an active company. Reports indicate the app has had updates in app stores, which suggests the product has not been shelved or abandoned.
The company has also expanded beyond the original consumer app. ReThink has moved into advocacy, education partnerships, and work that sits closer to the nonprofit space. This is a common path for mission-driven startups — the product stays alive, but the business model evolves around it.
It would not be accurate to call ReThink a major mainstream consumer hit. The available evidence supports that it is still active and still available, not that it has achieved wide commercial scale. But surviving without a confirmed Shark Tank investment is an achievement in itself.
What Trisha Prabhu Is Doing Now
Trisha Prabhu did not stop working when Shark Tank ended. She has continued as a public advocate for online safety and anti-cyberbullying efforts. She has given talks, built out the ReThink platform, and published a book.
Her work has expanded well beyond the original app. She has connected with education organizations, safety advocates, and institutions interested in how to protect young people online. The Family Online Safety Institute (FOSI) has recognized her role as founder and CEO in this space.
The fact that people are still searching for her name and the ReThink update years after the episode aired says something. Teen founders with a social mission and a working product tend to stick in people’s minds — and Prabhu’s story is a good example of that.
Does the Research Support the ReThink Approach?
The idea behind ReThink is not just a gut feeling. Research suggests that prompting users to pause before sending can actually reduce hurtful messages, particularly among adolescents.
The results from early testing supported the premise — that a simple interruption at the right moment could change behavior. That said, one study is not a full picture, and ReThink is designed to reduce impulsive harmful messaging, not eliminate cyberbullying entirely. That distinction matters.
The preventive model has logic behind it. Giving someone a second to think before they send is a low-cost intervention. If it works even some of the time, it has value — especially for a demographic that tends to act quickly and regret it later.
