What is a Sales Development Representative (SDR)?
A Sales Development Representative (SDR) is a specialized sales role dedicated to the top of the sales funnel. Unlike Account Executives who close deals, SDRs focus entirely on prospecting, qualifying leads, and booking meetings. They're the engine that feeds qualified opportunities into the sales pipeline.
Core Responsibilities
Prospecting Activities:
- Research and identify potential customers within the ICP
- Execute multi-channel outbound campaigns (email, phone, LinkedIn)
- Qualify inbound leads from marketing efforts
- Maintain accurate data in CRM systems
Lead Qualification:
- Conduct discovery calls to assess fit and need
- Apply lead scoring frameworks like BANT or MEDDIC
- Identify buying signals and decision-makers
- Determine budget, authority, need, and timeline
The SDR-AE Handoff
The most critical moment in an SDR's workflow is the handoff to Account Executives. A quality handoff includes:
- Comprehensive prospect research and context
- Clear pain points and business challenges identified
- Decision-making process and key stakeholders mapped
- Next steps and meeting objectives defined
Key Metrics and KPIs
Activity Metrics:
- Calls made per day (typically 50-100)
- Emails sent per day (typically 100-200)
- LinkedIn messages sent
- Accounts researched and added to sequences
Outcome Metrics:
- Meetings booked per week/month
- SQL (Sales Qualified Lead) conversion rate
- Pipeline generated (dollar value)
- Meeting show-up rates
Common SDR Mistakes
Over-pitching too early: Many SDRs jump straight into product features instead of discovering pain points. The goal is to earn the right to a conversation, not to sell the product.
Poor qualification: Booking meetings with anyone who says "yes" leads to wasted AE time and poor conversion rates. Quality over quantity always wins.
Inconsistent follow-up: Most deals happen after multiple touchpoints, but many SDRs give up after 2-3 attempts.
Technology Stack
Modern SDRs rely heavily on sales technology:
- CRM systems for lead management
- Sales engagement platforms for cadence automation
- Data enrichment tools for accurate contact information
- Intent data platforms to identify buying signals
- Email warmup tools to maintain sender reputation
Career Progression
The SDR role typically serves as a stepping stone to Account Executive positions. Top performers often transition within 12-24 months, bringing valuable prospecting skills and market knowledge to closing roles.
