We've gone from Cloud Week to Rocket Week, if you're watching stock market IPOs. Big-name startups Airbnb and DoorDash made their debuts this week, both raising far more money than they expected and shooting higher when they began trading.

Getting Up: Serial Entrepreneur Tom Siebel on Surviving an Elephant Attack

The week of C3.ai's IPO (it was previously known as C3IoT), I've got to share possibly the most harrowing story from my Fortt Knox archives: how Co-founder and CEO Tom Siebel (barely) survived an elephant attack.
