SDR vs BDR: What's the Difference in 2026?

If you're trying to break into tech sales, you've seen both "SDR" and "BDR" in job listings and wondered whether they're the same thing. Mostly yes, with one difference that shapes your day-to-day: where your leads come from.

Definitions

SDR: Sales Development Representative The SDR role is mostly inbound-focused. SDRs work the leads marketing has generated: people who've downloaded a guide, attended a webinar or started a free trial.

BDR: Business Development Representative The BDR role is mostly outbound-focused. BDRs prospect on their own and reach out to potential customers who have had no contact with the company yet, through cold emails, LinkedIn messages and cold calls.

The Reality at German Startups

Most early-stage German startups use "SDR" and "BDR" interchangeably. At a 15-person startup, your SDR role will include both inbound qualification and outbound prospecting. Scale-ups and enterprise companies are more likely to split the two.
