Hans Lemmens

Voice AI Specialist | Inbound & Outbound Agents | 700K+ Calls Automated

I build realistic, low-latency voice AI agents for inbound and outbound calling. Inbound agents: - 24/7 call answering - no missed leads, no voicemail - Lead qualification & appointment booking - Call routing & warm transfers to your team Outbound agents: - Instant follow-up on every new lead - Automated qualification at any volume - Database reactivation to re-engage old leads at scale - Appointment confirmations & reminders One agent I deployed made 700K+ calls, generated 5,600+ qualified transfers, and drove $823K in revenue for a single client - cutting cost per call from $35 to $15. I build on a proprietary voice stack - not a platform like Vapi or Retell. Conversations stay smooth at any volume, no latency spikes, and no concurrency limits when your campaigns scale.
