In-House SDR vs Agency
Hiring an SDR gives you control. Working with an agency gives you speed. Both work — but the math is almost never what people expect. Here's the real comparison.
In-House SDR
Hiring a dedicated sales development rep internally — full control, full cost, full ramp time.
Stellar Digital
Agency-delivered outbound — proven playbooks, faster ramp, predictable monthly cost with no hiring overhead.
Feature comparison
When hiring in-house is the right call
- ▸You have 50+ employees and a dedicated sales ops or revenue ops function to support an SDR
- ▸Your product requires 6+ months of product knowledge before someone can have a credible conversation
- ▸You've already validated outbound works and want to internalize the function
- ▸Your deal cycle is complex enough that a human needs to manage nuanced objections over 8+ weeks
When Stellar Digital is the right call
- ▸You're under 50 employees and can't afford the loaded cost, management overhead, and attrition risk
- ▸You need to move fast — 3 months of ramp is too slow for your current pipeline situation
- ▸You want to test whether outbound works for your ICP before committing to a full-time hire
- ▸You want a playbook built by people who've done this across dozens of verticals, not one person learning on the job
What actually sets Stellar Digital apart
The fully-loaded cost most companies ignore
SDR base salary runs $50k–$70k. Add commission (20–30% OTE), benefits (25–30% of base), management time, recruiting costs, and the tool stack (LinkedIn Sales Nav, Outreach, Apollo, Clay) and the true annual cost lands at $105k–$168k. A Stellar Digital retainer is $24k–$72k/year with tools included.
14-month average tenure
SDRs churn fast. The industry average tenure is 14 months. Every time an SDR leaves, you restart recruiting (60–90 days), pay a recruiter fee (15–20% of first year salary), and lose 3 months of ramp. That's 6 months of lost productivity per hire cycle. Agency relationships don't reset.
The institutional knowledge problem
An SDR who quits takes their learnings with them. At Stellar Digital, every ICP insight, reply pattern, and A/B test result is logged in the system. When the engagement ends, you have a documented playbook — not a person's memory.
Validation before commitment
Most companies aren't sure if outbound will work for their specific ICP. Running a 60-90 day agency engagement at $3k–$6k/mo is a far less risky validation than spending 6+ months and $80k+ hiring and ramping an SDR to find out the channel doesn't convert.

How much does a B2B SDR cost per year fully loaded?
An entry-level SDR earns $50k–$65k base with 20–30% OTE, meaning total cash compensation runs $60k–$85k. Add benefits (25%), tools ($800–$2,000/mo), recruiting fees, and management overhead and the fully-loaded annual cost is $105,000–$168,000.
What's the average SDR ramp time?
Industry research consistently puts SDR ramp time at 3 months to reach full productivity. During that period you're paying full salary while getting limited output. Agencies start generating pipeline from week one.
How long do SDRs typically stay at a company?
The average SDR tenure is 14 months. High ambiguity, repetitive work, and natural career progression toward AE roles means SDR churn is structural. Factor in a 6-month total cost to replace (recruiting + ramp) and you're restarting the process every year.
When does it make sense to bring outbound in-house?
Once you have validated playbooks, a defined ICP, and enough pipeline volume to justify a dedicated full-time person. Most companies should outsource to validate first, then hire once the system is proven. Hiring before validation is the expensive mistake.
Does Stellar Digital help transition to in-house later?
Yes. A Stellar Digital engagement ends with documented playbooks, a configured tech stack, and campaign archives you can hand to an in-house SDR or AE. The infrastructure is yours to keep — the hire just takes over running it.
