Zero awkward voice bot latencies, robotic glitches, or synthetic voices that trigger immediate hang-ups.

Professional SDRs know how to politely speak with executive assistants and front-desk receptionists to reach executives.

Hiring a full-time SDR costs $75,000+ in salary, software, and management. Zellpin charges +$3 per lead called with zero overhead.

Every interaction records prospect feedback, timing preferences, and conversion outcomes directly in your dashboard.

Why does Zellpin use human callers instead of AI voice bots?

AI voice bots create robotic latency, fail at objection handling, and alienate enterprise decision-makers. Real human SDRs build authentic relationships, navigate gatekeepers, and achieve significantly higher conversion rates.

How much does the human caller service cost?

Human SDR phone calling is an optional add-on at +$3.00 per lead called. Combined with our $2.00 verified lead generation, total cost is $5.00 for a fully researched and phoned prospect.

Who does the calling on behalf of my business?

Calls are executed by trained, vetted sales professionals with native fluency in target market business languages (English in the US, UK, and India).

Where do scheduled meetings get booked?

Qualified prospects are booked directly onto your Calendly, Google Meet, or Zoom link.
