You just sold your company. Maybe it was a nine-figure acquisition. Maybe it was a decade-long build that finally found the right buyer. Maybe you handed the keys to a private equity firm, or watched your life's work go public on an exchange. Whatever the shape of it, you're on the other side now. And somewhere in the back of your mind is a thought: someone should write this down. You're right. They should. The goal is to ensure your story stands the test of time.
