How to Scope Your First AE, SDR, or CSM

Updated: Apr 1

Hire too soon and you waste budget. Hire the wrong role and you stall growth. Here's how to get it right.


Hiring your first customer-facing rep is one of the most important decisions you'll make as a founder. The wrong role at the wrong time costs you money, momentum, and trust — from candidates and customers alike. The right decision depends on a clear read of where you actually are, not where you want to be.

Most founders hire for where they're going. The best hire for where they are — and scope the role to get them there faster.

Step 1: Know your traction level

Before deciding on a role, be honest about your current state. Are you pre-revenue, still validating ICP and pricing? Are you in early revenue ($0–$1M ARR) with some repeatability emerging but still founder-led? Or do you have real traction ($1–$5M ARR) with consistent pipeline and defined messaging? Each of these stages points to a different first hire — and different criteria within that hire.


Step 2: Know your GTM motion

Sales-led SaaS with longer cycles and multi-stakeholder deals needs different skills than a PLG or hybrid model with self-serve and fast expansion plays. Knowing your motion tells you whether you need hunters, guides, or expanders — and shapes what "good" looks like for each role type.


Which role comes first?

Pre-revenue or just closed first deals

Don't hire yet — or hire very carefully


Founders should lead the first 10 to 20 deals. It's essential learning that no hire can replicate for you. If bandwidth is truly maxed, consider a contractor to test outbound, a junior AE who shadows you, or a player-coach who can execute and also build systems. Prioritize flexibility, curiosity, and storytelling over polish.

Validated ICP, need more pipeline

SDR or full-cycle AE depending on your ACV


Under $10K ACV with fast cycles: hire an SDR to drive volume and qualify interest. $10K+ ACV or consultative deals: hire a full-cycle AE who can prospect and close without RevOps or heavy enablement. Look for reps who know your ICP or have worked in lean, startup environments.

Closing customers, need to retain and grow

CSM or hybrid AM/CSM


Especially important with usage-based pricing, complex onboarding, or multi-stakeholder accounts. A CSM frees up your AEs to focus on new business while building the long-term trust that drives expansion revenue.


Final filters before you decide

  1. Deals stalling because of pipeline volume?

    → Hire an SDR


  2. Deals stalling because of close rate or deal quality?

→Hire an AE


  1. Churn or onboarding slowing growth?

→ Hire a CSM


  1. Need to close deals now and build for scale?

→ Hire a player-coach AE


The best founders resist the urge to hire before these questions have clear answers. The role you scope shapes who applies, what you evaluate, and whether the hire actually moves the number.
