How Kallix automated 30,000+ minutes of sales & support calls with AI voice agents

Kallix builds custom AI voice agents that handle sales calls, appointment booking, and customer support around the clock. Reinforce helped them train multilingual agents across Hindi, English, and regional Indian languages — reaching human-level accuracy with zero dropped context across 30,000+ call minutes per month.

Key outcomes

30,000+ AI call minutes handled monthly with zero human intervention on qualifying calls.
30% reduction in missed leads due to 24/7 availability across all channels.
Multilingual fluency across Hindi, English, Bengali, and four regional Indian languages.
Average handle time reduced by 40% versus human agents on the same call types.

The challenge

Kallix's clients were losing qualified leads to unanswered calls during evenings, weekends, and lunch hours. Human agents could handle 8–10 calls per hour maximum. As client rosters grew, staffing costs scaled linearly — an unsustainable model for a voice-AI company promising automation.

How Reinforce helped

01
Curriculum designReinforce built a simulation curriculum covering the top 200 call scenarios per vertical — objection handling, booking flows, escalation triggers.
02
Multilingual fine-tuningAgents were fine-tuned on code-switched transcripts (Hinglish, Bengali-English) using a preference dataset curated by native-speaker reviewers.
03
Eval harnessA shadow-deployment eval suite ran the trained agents against recorded real calls before live traffic was handed over. Pass threshold: 94% intent accuracy.
04
Continuous improvement loopWeekly reward signal updates from live call outcomes (booking confirmed / lead dropped) automatically retrain the agents without manual annotation.

“We went from a waitlist of clients we couldn't serve to a fleet that scales instantly. Reinforce gave us the training infrastructure we didn't have time to build ourselves.”
