Ev Williams is the Nebraska farm boy who accidentally invented blogging, co-founded Twitter, built Medium, and is now trying to make social media actually social again with Mozi. A serial founder who has shaped how the world communicates - and who openly regrets some of what that meant - he remains one of tech's most quietly consequential figures, running Obvious Ventures, a B Corp impact fund with $585M in assets, while incubating his next idea from San Francisco.
Tim Denning is an Australian writer, blogger, and online educator who went from a $32K/year bank call center job to 1 billion+ views across platforms and $6M+ earned through writing. He runs the 'Modern Freedom' Substack newsletter (151,000+ subscribers), teaches writing at Bad-Assery Academy, and publishes 10 articles per week on Medium, LinkedIn, and his personal site - all built on a philosophy of radical vulnerability, strategic imperfection, and the pursuit of time freedom over net worth.
