Hiring breakpoints: when adding headcount hurts more than it helps
Most founders treat hiring as a linear problem: more people means more output. The math is wrong, and it gets more wrong the larger your team gets.
A post on Stay SaaSy breaks down the key team size thresholds where incremental hires stop delivering proportional value and can actively make things worse.
The breakpoints that matter
The two most consequential early breakpoints are 0 to 1 and 7 to 10 employees. These are the ranges where hiring decisions have outsized impact on team effectiveness, not just because of the workload the new person carries, but because of how they change coordination costs for everyone already there.
The Dunbar number problem
The bigger structural shift happens when a company crosses roughly 150 employees, also known as the Dunbar number. Beyond that threshold, productivity per hire generally decreases. The informal coordination that works at smaller sizes breaks down, and without robust formal structures in place, communication overhead eats into the output gains you hired for.
The operator takeaway: if you’re approaching 150 people without deliberate coordination systems, the next hire may cost you more in friction than they deliver in capacity.
