An SDR prospects and qualifies leads, then hands booked meetings to an account executive.
Key points
- SDRs manage top-of-funnel work such as Prospecting and Lead Qualification, and create opportunities for account executives [1].
- The SDR and Business Development Representative (BDR) titles are often used interchangeably; where they differ, one tends to handle inbound and the other outbound [1].
- Core SDR metrics are activity volume, Positive Reply Rate, meetings booked and meetings accepted as qualified [2].
- Dedicated sales development teams date back to the early 1980s at Oracle, and the model spread widely across B2B technology companies [3].
- SDRs typically work from a Lead List or Target Account List and run sequences across email, phone and social channels.
- The AI SDR category automates parts of the SDR workflow, such as research and first-draft emails.
What an SDR does
An SDR's day centers on creating conversations. That includes researching accounts that fit the Ideal Customer Profile (ICP), finding the right contacts, writing or personalizing outreach, following up and qualifying anyone who responds. Salesforce describes SDRs as owning presales tasks like prospecting and lead qualification so that account executives can focus on closing [1]. When a prospect is interested and appears qualified, the SDR books a Discovery Call and hands the context to the AE. In some companies SDRs mainly follow up on inbound leads from marketing, and in others they focus on cold Outbound Sales. Either way, the job is measured by pipeline created rather than revenue closed.
Why companies split the role
Specialization is the main reason SDR teams exist. The book Predictable Revenue, based on Aaron Ross's work at Salesforce, argued that asking closers to also prospect leads to inconsistent pipeline, because closing work always crowds out prospecting. The idea itself is older: sales development teams that sit between marketing and sales can be traced to Oracle in the early 1980s [3]. Separating the roles lets each person focus and creates a clear career path, with many SDRs moving into AE roles after one to two years. Benchmark research from The Bridge Group tracks SDR ramp time, tenure, quota and compensation, and consistently shows that the role is demanding, with relatively short average tenure [2]. For early startups, the founder often does SDR work directly until there is enough repeatable demand to hire.
SDR work and automation
Much of an SDR's time goes to research and writing, which are the parts most suited to software. Tools now handle Lead Enrichment, Email Personalization and scheduling, while the SDR focuses on judgment calls and live conversations. PineLead covers a slice of this workflow for small teams and founders. It finds new prospects every day, qualifies each one against your ICP criteria as a fit, a maybe or a reject, researches the company and drafts a personalized first email in your voice. You review and approve each draft, or turn on Auto-Approve for fitting prospects. Emails go out from your own connected mailbox under a daily sending limit, and replies come back in the thread.
