BDR is often used interchangeably with SDR, but where a distinction is drawn, BDRs typically focus on outbound-only prospecting against named target accounts, while SDRs handle a mix of inbound qualification and outbound. The naming convention varies by company.
BDR teams typically run multi-channel sequences (email, phone, LinkedIn, video) against an account list curated with the AE. Their measure is meetings booked with decision-makers in target accounts.
