How flat hierarchy almost killed my startup

CareerFoundry had a flat hierarchy for just a year. It was a rollercoaster, mainly downwards. Although now, we are maturing and really finding our rhythm with sales up 100% since we moved away from being flat, and turned profitable for the first time in 2017. Now that we are in a much better place, it’s the right time to discuss our journey through a flat hierarchy , and how I turned from being positive about flat hierarchies to being completely against them.
