In this episode of Root Cause we sit down with Orel Zilberman, the solo builder behind WriteStack, the biggest tool out there for Substack creators. Orel spent 599 days shipping around ten products that made zero dollars, then picked one thing, stuck with it for six months, and turned it into a six-figure business. He has lived three versions of solo building in three years: before the current AI tooling, as it arrived, and now. We get to the root cause of what AI actually changed for one-person companies and what it didn't. Building got faster, but knowing what to build, and sticking with it long enough to find out if it works, is exactly as hard as it always was. Honest and unfiltered, including the messy parts most "become an entrepreneur" content leaves out.
