《Shark Tank》：Jeff Wittens 重新設計了 CoinOut 的模型並將其轉變為應用程式

傑夫的商業模式最初受到了鯊魚們的挑戰，他們不確定其市場潛力。

Jeff Witten appeared on Shark Tank in 2018, seeking a $250,000 investment for a 7.5% stake in CoinOut, a company that digitized loose change. Despite facing skepticism from the sharks, Jeff received three offers and ultimately shook hands with Robert Herjavec on a deal for $250,000 in exchange for 15% equity.

Jeff Witten 於 2018 年出現在 Shark Tank 節目中，尋求 25 萬美元的投資，以獲得 CoinOut 7.5% 的股份，CoinOut 是一家將零錢數位化的公司。儘管面臨鯊魚隊的懷疑，傑夫還是收到了三個報價，並最終與羅伯特·赫賈維克握手，以 25 萬美元的價格換取 15% 的股權。

However, the deal with Robert fell through after the show, and Jeff later remodeled CoinOut into a cash-back rewards app. In 2021, CoinOut was acquired by Information Resources, Inc. (IRI), and the app is still available on Google Play and the App Store.

然而，演出結束後，與 Robert 的交易告吹，Jeff 後來將 CoinOut 改造成一款現金返還獎勵應用程式。 2021 年，CoinOut 被 Information Resources, Inc. (IRI) 收購，該應用程式仍可在 Google Play 和 App Store 上使用。
