A Sales Development Representative (SDR) is a sales professional who focuses exclusively on the early stages of the sales process—finding potential customers, reaching out to them, and qualifying their interest before passing them to closers. Think of SDRs as the pipeline builders who ensure your sales team always has qualified prospects to work with.
Why SDR Matters in B2B SaaS
SDRs have become essential to scalable GTM architecture in B2B SaaS. Companies with dedicated SDR functions generate 20% more sales opportunities than those without[1], while SaaS businesses using SDR teams grow 38% faster[2]. This specialization addresses a critical challenge: 65% of B2B marketers cite generating traffic and leads as their biggest obstacle[3]. SDRs bridge this gap by creating systematic, predictable pipeline generation that supports sustainable growth.
Who Uses SDR
SDRs are implemented across multiple teams within B2B SaaS organizations. Sales development teams execute daily prospecting and outreach activities, while sales managers oversee SDR performance and pipeline contribution. Marketing teams collaborate closely with SDRs to optimize lead handoffs and campaign effectiveness.
Decision-makers include VPs of Sales, Chief Revenue Officers, and Sales Development Directors who recognize that 70% of B2B SaaS companies with $10M+ ARR employ at least one SDR per account executive[4].
How SDR Drives Growth
SDRs accelerate pipeline velocity by ensuring faster lead response times. Companies responding to leads within five minutes are 100x more likely to connect and 21x more likely to convert[5]. Top-performing SDR teams respond to leads under one hour 78% of the time[6].
The average SDR books 15-25 meetings per month[7], creating consistent pipeline flow that enables predictable revenue growth. This systematic approach transforms sporadic lead generation into repeatable, measurable results.
