| This is How I Work, a series where founders, CEOs and leaders share the essentials that help them do what they do, from their morning routines to productivity tools. The beginning of Brian Cook’s career as an entrepreneur will sound familiar: 80-hour work weeks, no time off on the weekend, productivity taking precedence over personal relationships. That’s the playbook that’s been pitched to business upstarts for the last few decades, and in some respects it’s worked beautifully for Cook. At 58 years old, he’s founded and sold a number of companies, including workflow software firm Nintex and employee directory app Hyperfish. These days, he’s now shepherding a new firm from its explosive startup phase into its foundational phase, and we bet you can guess the tech they’re working on. |
