Jyoti Bansal is a serial entrepreneur, through and through. In 2008, he first made the leap from startup engineer to CEO with AppDynamics, a company that was acquired by Cisco for $3.7 billion just under a decade later. After giving retirement a shot, he returned to the founder seat: he started software delivery unicorn Harness, cybersecurity platform Traceable, startup accelerator BIG Labs, and VC firm Unusual Ventures—and has more than 25 US patents under his name. Jyoti shares his simple formula for finding product-market fit, why ringing the Nasdaq closing bell was part of his Cisco negotiation, and how he's learned not to stress about things outside of his control.
