In a remarkable journey that many entrepreneurs dream of, Jyoti Bansal, founder of AppDynamics, sold his startup for a staggering $3.7 billion. However, instead of celebrating, he faced what he calls his “saddest day.”

Bansal, now 46, built AppDynamics to address critical software issues as a former engineer in Silicon Valley. The company gained a solid reputation for helping major corporations troubleshoot application problems. Just as they were preparing for an IPO in 2017, tech giant Cisco made a last-minute acquisition offer that changed everything.

While the sale made Bansal and many of his employees instant millionaires, the moment became bittersweet. “I spent nine years fully dedicated to what we were building,” he said. “Suddenly, it felt like the end of a chapter.”

Initially taken aback by Cisco’s surprise offer, Bansal faced a tough decision amidst sleepless nights filled with intense discussions. The financial reward was life-changing for many of his employees, but Bansal soon realized he hadn’t fulfilled his vision for AppDynamics. He felt a sense of aimlessness without a significant problem to solve.

After six months of travel, he founded Harness, a new startup focusing on software tools for developers. By 2022, Harness was valued at $3.7 billion, mirroring his previous venture’s sale.

Reflecting on his choice to sell AppDynamics, Bansal acknowledged the complexities of entrepreneurial life. “I really enjoyed building the company,” he admitted. “It was intense and stressful, but I loved it.”

As he now considers a potential IPO for Harness, Bansal is clear: a similar acquisition offer would likely be turned down. “We want to reach billions in revenue and expand our impact,” he stated. “It doesn’t make sense to sell now; our journey is just beginning.”

This introspective account highlights the emotional intricacies of entrepreneurship, revealing that even monumental successes can come with profound regrets.
