CATE App: What Happened After Shark Tank? The Controversial App’s Fate

February 19, 2026 Rachel Kim – Technology Editor Technology

The CATE App, a smartphone application designed to conceal calls and texts, is no longer in business, according to reports from June 2025. The app, short for “Call and Text Eraser,” gained notoriety after appearing on the fourth season of the television show Shark Tank in 2012.

Neal Desai pitched the CATE App to the panel of investors, seeking $50,000 for a 5% stake in the company. At the time, the app had over 5,000 subscribers, each paying $4.99 for a download. Desai acknowledged the valuation was a starting point for negotiation.

The app’s premise – masking notifications from blacklisted contacts – immediately drew scrutiny from some of the “Sharks.” Robert Herjavec and Mark Cuban expressed discomfort with the app’s potential use in facilitating infidelity and declined to make an offer. However, Kevin O’Leary and Daymond John showed interest, contingent on Desai rebranding the app to emphasize privacy rather than secrecy in relationships.

Desai reached a deal with O’Leary and John, seemingly swayed by O’Leary’s experience in the software industry. Despite the on-air agreement, the deal was never finalized during the due diligence period following the show, a situation mirroring the experience of the Hopscotch app from Season 12 of Shark Tank.

The CATE App’s origins predate Desai’s involvement. The app was initially conceived by Phil Immler, a police officer, as a tool to de-escalate domestic disputes stemming from concerns over partners’ phone activity. Desai, however, envisioned a different market for the technology.

Following the Shark Tank episode, the app saw a surge in downloads, reportedly reaching 10,000, with a majority of users identified as women. This initial interest did not translate into sustained growth, and the app is no longer available for download. Desai reportedly attempted to market the app to federal agencies as a confidentiality tool for sensitive information, but these efforts were unsuccessful.

As of February 2026, the CATE App’s online presence is limited to a dormant YouTube channel, with the last video uploaded 14 years prior. A linked website appears to be defunct. Despite its failure, the app continues to be discussed on online forums, a testament to the controversy surrounding its original marketing angle.
