BDR vs SDR
BDR usually means inbound (qualifying inbound leads), SDR usually means outbound (cold prospecting). Some teams flip the convention. Inside one company the distinction matters; across companies it's noisy.
What a BDR actually does
Reads inbound form fills, looks up the company, scores against ICP, runs a quick discovery call, and either books a demo with the AE or disqualifies.
Tooling overlap with SDR
Same stack: CRM, sequencing tool, enrichment. Less LinkedIn outreach since the lead reached out first.
