What is an SDR?

A Sales Development Representative (SDR) is the outbound role responsible for sourcing new pipeline — the cold-to-meeting motion. SDRs hand qualified meetings to Account Executives.

SDR vs BDR

Most teams use SDR for outbound (cold prospecting) and BDR for inbound (qualifying inbound leads). Some use them interchangeably.

What an SDR actually does

Builds prospect lists from ICP, sends multi-touch outreach across LinkedIn, email, and phone, qualifies replies against discovery criteria, and books the meeting on the AE's calendar.

Common SDR tooling

Sales Navigator for sourcing, Outreach or Salesloft for cadences, ZoomInfo or Apollo for enrichment, and a CRM (HubSpot, Salesforce) for pipeline. Increasingly: AI personalization layers like Infonet.

Hiring vs Infonet

An SDR runs ~$5–8k/month fully loaded. Infonet from $39/mo can replicate 60–80% of an SDR's volume on the LinkedIn channel for solo founders and small teams.
