The Series A Hiring Playbook: 10 Roles That Define Your Next Stage

Congratulations on your Series A. Now comes the hard part: turning capital into growth. The hires you make in the next 12 months will determine whether you're ready for Series B or running out of runway.

The Post-Series A Reality

You probably have:

Here's the playbook that works.

The First 90 Days: Foundation Hires

1. Head of Sales or First AE

If you don't have repeatable sales yet, you need someone who can close deals AND document the playbook. Look for someone who's done early-stage sales before.

2. Senior Product Manager

Founders can't run product forever. This person owns the roadmap so you can focus on company building.

3. Marketing Lead (Growth Focus)

Not a brand marketer—someone who can build pipeline. Demand gen, content, and performance marketing skills.

Months 3-6: Scaling Hires

4-5. Engineering (Based on Roadmap)

Hire ahead of your product roadmap, not behind it. You should have engineers starting before features are specced.

6. Customer Success Manager

Once you have 20+ customers, someone needs to own retention. Churn kills Series A companies.

7. First Sales Development Rep (SDR)

Once your AE is closing, they shouldn't be prospecting. SDRs are pipeline fuel.

Months 6-12: Leadership Layer

8. VP of Engineering (If Not Already)

At 10+ engineers, you need dedicated technical leadership.

9. Head of Customer Success

If your CSM is overwhelmed, it's time for leadership.

10. Finance/Operations Lead

Someone to own the systems that let you scale—billing, analytics, compliance.

The Roles to Avoid (For Now)

Hiring Velocity

A healthy Series A company adds 1-2 people per month. Faster than that creates cultural integration problems. Slower means you're not capitalizing on your runway.

The Bottom Line

Series A is about building the team that can 3x your business. Every hire should directly contribute to ARR growth or enable those who do.
