What Is an SDR (Sales Development Representative)?
An SDR — Sales Development Representative — is a sales professional responsible for outbound prospecting and qualifying leads. If you're wondering what an SDR is and why the role matters, here's the short answer: SDRs are the front line of B2B sales, generating the pipeline that Account Executives close.
What Does an SDR Do?
SDRs focus on the top of the sales funnel. Their primary activities include:
- Cold calling prospects to introduce the company and book meetings
- Cold emailing to engage buyers who don't respond to calls
- LinkedIn outreach to connect with decision-makers
- Lead qualification to ensure meetings are with the right people
- CRM hygiene — logging calls, updating contact records, and tracking activity
The key metric for most SDRs is meetings booked or qualified opportunities generated. Unlike Account Executives (AEs), SDRs typically don't carry a closing quota — they hand off qualified prospects to AEs for demos and negotiations.
SDR vs. AE: What's the Difference?
| | SDR | AE | |---|---|---| | Focus | Prospecting and qualifying | Closing deals | | Quota | Meetings booked | Revenue closed | | Activities | Calls, emails, LinkedIn | Demos, proposals, negotiations | | Funnel stage | Top of funnel | Mid to bottom of funnel |
Most B2B sales careers start in the SDR role. High-performing SDRs typically promote to AE within 12–18 months.
Core Skills Every SDR Needs
Cold Calling
The ability to engage a stranger on the phone, deliver a concise value statement, and book a meeting in under two minutes. See our complete guide to cold calling for the full breakdown.
Objection Handling
Prospects say "no" far more often than "yes." SDRs need to navigate objections around timing, budget, interest, and authority without getting rattled. Our objection handling guide covers the framework.
Time Management
Top SDRs batch their activities — calling blocks, email blocks, research blocks — to maximize output. Discipline with the calendar separates good SDRs from great ones.
Coachability
The best SDRs actively seek feedback, review their own calls, and practice deliberately. This is where AI-powered sales training makes the biggest impact — giving reps unlimited practice reps without waiting for manager availability.
How AI Helps SDRs Ramp Faster
New SDRs face a steep learning curve: new product knowledge, unfamiliar personas, and the pressure of hitting activity targets from week one. Traditional onboarding relies on call shadowing and role-plays with managers — both limited by availability.
Vozah gives SDRs an AI practice partner available 24/7. New reps can:
- Simulate cold calls before dialing real prospects
- Practice handling the most common objections
- Get scored on tone, pacing, and technique after every session
- Track improvement over their first 30, 60, and 90 days
Teams using AI practice during onboarding see SDRs hit quota 40% faster than those relying on traditional training alone.
