Why Startup Exec Hires Fail — And How to Avoid €250K Mistakes

The brutal truth about leadership hiring in startups — and how diagnostics can protect your burn rate.

Hiring your first VP or C-level exec? You might be gambling with your startup’s future — and the odds aren’t in your favor. Over 50% of startup leadership hires fail within 18 months. That failure isn’t just frustrating — it could cost you up to €250,000 or more.

Dominik Roth, headhunter and host of CEO Career Code, has made over 400 executive placements in VC/PE-backed startups across Europe. In this conversation with Startuprad.io, he unpacks why hiring mistakes happen — and how startup founders can avoid becoming a case study in failure.

🔍 The Startup Leadership Hiring Trap

  • Founders often rely on gut feeling — what Germans call Bauchgefühl — over structured evaluation.

  • They prioritize charisma or networks over real capabilities.

  • Diagnostic hiring flips the script by using psychology-based assessments, not just CVs or interviews.

“Even headhunters can’t beat the 50% failure rate unless they apply diagnostics,” says Roth.


🧪 What Actually Works: Diagnostic Hiring

Here’s Roth’s 3-step process:

  1. Behavioral Interviewing: Testing not just personality, but context-specific behavior.

  2. Cognitive Ability Assessments: Does the candidate adapt fast and think under stress?

  3. Cultural Fit Testing: Not “do we like them,” but “do they thrive in ambiguity?”

“We shouldn’t infer sales competence from charisma. That’s a bias.”


⚠️ The First VP Mistake

Hiring your first VP of Sales or Marketing? Watch out for:

  • Overvaluing past network

  • Confusing extroversion with execution

  • Failing to define what is must-have vs. nice-to-have

“You can’t hire someone with every trait on your wish list. Hire for trajectory and fill the gaps with your team.”


😓 Founder Burnout from Mishires

Many founders hang on to non-performers too long. This leads to:

  • Emotional exhaustion

  • Reputational damage

  • Burn rate acceleration

“Startups aren’t families. Investors expect performance, not paternalism.”


📈 Timeline to Hire Right

  • Roth’s average search process = 10 weeks

  • Add 3–4 months for notice periods

  • Some CxO hires may take 6–9 months, depending on availability

“Founders underestimate how long real hiring takes — and overestimate their ability to ‘feel it out.’”


🧠 What Top Startup Leaders Actually Share

  • Ability to make fast decisions with limited data

  • Comfort with conflict and unpopular choices

  • Not always “team players” — but always company-first
