What is SDR (Sales Development Representative)?

A Sales Development Representative (SDR) is a specialized sales role focused exclusively on the top of the sales funnel — prospecting, outreach, and initial qualification — rather than closing deals. SDRs use multi-channel outreach (email, LinkedIn, phone) to identify and engage potential customers, qualify them against ICP and BANT criteria, and book discovery meetings with Account Executives. The SDR role was popularized by Aaron Ross's Predictable Revenue methodology and has become standard in B2B SaaS companies as a way to separate the hunter and farmer roles in the sales organization.

SDR (Sales Development Representative) is a critical concept for any B2B revenue team because it directly impacts pipeline predictability and revenue growth. Without a clear understanding of SDR (Sales Development Representative), teams often make decisions based on incomplete information or misaligned frameworks — leading to poor forecasting, wasted outreach effort, and missed quota. DevCommX incorporates SDR (Sales Development Representative) thinking into every SDR Outsourcing engagement we run.

SDR (Sales Development Representative) is closely connected to BDR (Business Development Representative) and AE (Account Executive), and several other core GTM concepts. In the context of GTM Engineering, SDR (Sales Development Representative) typically informs how revenue systems are designed, what data is tracked, and how performance is measured. Modern GTM Engineers treat SDR (Sales Development Representative) as a quantifiable lever — not just a concept — building automation and reporting that makes it visible and actionable.
