After interviewing more than 180 CTOs on my podcast and working with dozens of scaling software organizations, I have come to believe something different. They have a coordination problem. And it is costing them far more than they realize.I call it the coordination tax. It is the invisible overhead that accumulates whenever a new engineer is added to a team beyond a certain inflection point. The math is unforgiving. Each additional engineer introduces roughly 15% to 25% of coordination overhead while delivering only 5% to 10% of net output gain. Somewhere between engineer 15 and engineer 25, the curve inverts. You are paying for more headcount and receiving less throughput.Nobody puts this on the P&L, but it is there.The Hidden Math On A 30-Person TeamConsider a typical growth-stage software organization with 30 engineers. Fully loaded, that team represents somewhere between $6 million to $9 million in annual cost. If even 15% to 20% of that capacity is being absorbed by coordination overhead (meetings that exist to align people who should not need to be aligned, handoffs between teams that should own the work end to end, context switching caused by fuzzy decision authority), you are looking at $900,000 to $1.5 million per year in waste. Per year. Every year.And the number grows, not shrinks, as you hire.This is the part most leaders miss. Adding engineers does not dilute the coordination tax. It compounds it. The communic...
