AI SDR: an AI sales development rep that calls and messages every lead

An AI SDR (AI sales development representative) is an AI sales agent that does the first part of the sales job for you: it contacts every new or old lead by phone call, WhatsApp or email, asks your qualifying questions, handles common objections, books meetings with your closers and logs everything in your CRM. With Jelliu you launch one without code. Start on the Free plan (15 voice minutes every month, no credit card); paid plans start at $79/month.
