Shark Tank：Jeff Wittens 重新设计了 CoinOut 的模型并将其变成了应用程序

杰夫的商业模式最初受到了鲨鱼们的挑战，他们不确定其市场潜力。

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 于 2018 年出现在 Shark Tank 节目中，寻求 25 万美元的投资，以获得 CoinOut 7.5% 的股份，CoinOut 是一家将零钱数字化的公司。尽管面临鲨鱼队的怀疑，杰夫还是收到了三份报价，并最终与罗伯特·赫贾维克握手，以 25 万美元的价格换取 15% 的股权。

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，演出结束后，与 Robert 的交易告吹，Jeff 后来将 CoinOut 改造成一款现金返还奖励应用程序。 2021 年，CoinOut 被 Information Resources, Inc. (IRI) 收购，该应用程序仍可在 Google Play 和 App Store 上使用。
