**1M+**calls handled in production

**63**AI agents live across 90+ languages

**350,000+**conversations every month

## The Challenge

Businesses wanted AI handling customer calls, lead qualification, follow-ups and appointment scheduling. But connecting a language model to a chat window produces something that answers questions, not something that books the appointment, updates the record and knows when to fetch a human. xAIa needed AI employees that could work across multiple channels and act inside the systems a business already runs.

## The Engineering Strategy

HashOne Global built the xAIa platform end to end: application, backend, AI orchestration, integrations and infrastructure. Vapi carries real-time voice, the WhatsApp Business API carries messaging, and the orchestration layer we built sits between them and the client's calendars, CRMs and APIs.

That layer is the engineering. An agent receives a conversation, reads intent, applies business rules, accesses what it needs, executes the action, and escalates to a human where judgement is required. It is the difference between an AI that responds and one that operates.

## The Result

- **1M+** calls handled in production
- **63** AI agents live across 90+ languages
- **350,000+** conversations every month

Now running across multiple industries, which is the harder test: the architecture holds up against workflows it was not specifically designed around.
