Cost of a Bad Hire

Something that's been on my mind for a while: what is the true cost of a bad hire? I've dealt with a few over the years, but today I want to focus on two specific cases at my current company, and how each of them cost us far more than their salary.

Wrong Builds

Both were senior hires. That means part of the job is setting direction for other teams and contributing to overall company strategy. But over and over, they failed to identify real market opportunities and growth potential, while pushing hard for builds that were either wrong or simply didn't matter.

The frustrating part isn't that they made mistakes — everyone does. It's that they had conviction in the wrong things, and that conviction had weight.

Opportunity Cost

A startup doesn't have infinite budget or manpower. Every hire is a bet, and these two were expensive losses. Beyond just picking the wrong things to build, having them in those seats meant we didn't have the right people there. People who could have identified the correct builds, moved faster, and competed more efficiently.

Instead, we spent significantly more engineering time than our competitors chasing the wrong problems. For a small startup, that kind of inefficiency isn't just painful, it's existential.

Morale Destruction

This one is harder to quantify, but it might be the most damaging. When your team looks to senior figures for direction and inspiration, and those figures consistently miss the mark, people start asking themselves why they joined in the first place.

I watched this happen in real time. Good engineers, people with options, started quietly questioning things and eventually left. Turnover from a cultural mismatch is expensive on its own, but losing capable people because they've lost faith in leadership is a different kind of loss.

The Bottom Line

A bad hire at the senior level doesn't just underperform. They actively shape the wrong direction, consume resources that can't be recouped, and erode the trust that holds a team together. The salary is the smallest part of the cost.
