The True Cost of a Bad Technical Hire

For founders hiring engineers they can't evaluate themselves · by HireSphere AI

Two blocks, kept apart. Block 1 is what the open seat has cost so far and what it costs each month it stays open, in your numbers. Block 2 is the expected cost of hiring the wrong person, as a sourced range. Nothing is pre-filled. Leave any line you cannot put a number on blank, and it counts as nothing.

Block 1. What the open seat has cost, in your numbers

Salary divided by 12 is a stand-in for the work you are missing, not a measurement, and not cash out the door, since the salary is not being paid while the seat is empty. If this seat produces revenue you can put a monthly figure on, use that instead, for this seat only, never a company average.

Line 1: your number a month
Line 2, the seat's own lost output in the months nobody covered it: 0

Only the people and spend tied up in the slipped work, never total company burn.

Line 4, roadmap delay: 0

Only if you can name it: a client, a deal, a deadline. Not the same thing as line 4.

Line 5: 0

Your own expectation. If you have none, search firms publish 90 to 120 days for executive searches (recruiter-published, 2026).

Line 6, if it takes the months you expect: 0

Each line counts something no other line counts. Line 2 is the seat's own lost output in the months nobody covered it. Line 3 is the covering team's own work that did not get done in the months they covered it, at their cost, never the seat's salary. Line 4 is only the burn carried by the delayed work. Line 5 is counted only when you name it and it is not already line 4. Line 6 looks forward and never overlaps 2 and 3.

Kept apart from block 1 on purpose. The 2 totals are never added.

Block 2. The expected cost of the wrong hire

Your own record sets the share of hires that do not work out. Only when both are blank does the published 46% apply: Leadership IQ, 2011, across all hires, not senior seats. Your own record replaces it.

Line 9, share of hires that do not work out: 46% (published, all hires)

Gallup, 2019, an estimate, not a measured result.

Block 2. The expected cost of the wrong hire

Gallup estimates that replacing an employee can cost half to 2 times that employee's annual salary (Gallup, 2019). It is an estimate range, not a measured result. Morale, team drag and missed market windows are not in either block. Leadership IQ's 2011 survey of 5,247 managers found that, looking back, 82% said they had seen warning signs during the interview process. The signs are usually there. What is usually missing is a process that writes them down.

Bring this to your Alignment Call. We start from your numbers.

Don't roll the dice on the next one.

"How can you evaluate technical candidates if I can't?" That's exactly what the Alignment Engine is for and why we break it into 4 critical steps:

  1. Hiring Strategy Blueprint: We define what good looks like for the role, for your company, at your stage, based on your values & leadership principles.
  2. Candidate Pipeline & Interview as a Service: We use the Blueprint to build the candidate pool, and only candidates who clear the bar written for the seat reach interview. We then run structured behavioral interviews and technical assessments and hand you a ranked top 3 with the reasoning written down. A trained human evaluator makes every assessment. You make every hiring decision.
  3. Placement & Systems Implementation: Recruiters fill a seat. We also wire a 30-60-90 plan in from day one, and we stay with you until your hire completes their first 90 days.
  4. Upleveling: Once the hire is confirmed and ramped, we use what the evaluation showed to plan their development in the seat.

12-month replacement guarantee on Alignment Engine placements. It is a replacement guarantee, not a refund.
