A Sales Development Representative (SDR) is a specialist in identifying, qualifying, and generating sales opportunities for the commercial team. In technology companies, SDRs are essential for filtering leads and ensuring that salespeople speak only with qualified prospects. Their work includes researching potential clients, making the first contact (via email, calls, or LinkedIn), and scheduling meetings for Account Executives. They use tools like Outreach.io, Apollo.io, or HubSpot to optimize their workflow and increase efficiency. Their success is measured by the number of meetings scheduled and the conversion of leads into business opportunities. By freeing up time for closing salespeople, SDRs help scale the sales process and increase team productivity.
