# The 10 Most Expensive Series A Hiring Mistakes

Series A is a critical inflection point. Here are the mistakes founders make most often.

Mistake 1: Hiring Too Senior Too Fast

Bringing in VPs and Directors before you have the team to manage costs $200-400K for someone doing IC work.

Mistake 2: Not Moving Fast Enough

Taking 3-4 months to fill critical roles means missed opportunities and founder burnout.

Mistake 3: Ignoring Culture Fit

Hiring skilled people who do not align with your values causes team dysfunction.

Mistake 4: Skipping Reference Checks

Not talking to former managers means hiring people with hidden performance issues.

The Bottom Line

Most hiring mistakes are predictable and preventable. Slow down enough to hire well.
