We build the real-time plumbing that lets software hold a natural spoken conversation — and the products that prove it works, in production, before we ask anyone to trust it.
A real-time voice-agent API. Send your agent's persona, pick a voice, plug in your own tools or MCP server — your users are talking to it in under a second. Per-turn latency and cost on every receipt, full transcripts, AI self-disclosure built in.
The conversational travel-care technology behind CareLine: when a flight falls apart, a calm voice calls, re-protects the journey and settles the details — bookings, hotels, transfers — while the traveler just talks.
Talk to us →Detects flight disruptions, rebooks passengers, arranges care and processes compensation — before your team picks up the phone. Built for airline groups of any size.
Request a demo →The integration fabric underneath: flights, hotels, ground transport, payments and voice channels behind one disciplined contract — the same connectors our own products run on.
Talk to us →Every number we publish exists on an internal scoreboard first. Latency is measured voice-to-voice, costs are metered per turn, and our agents always disclose that they are AI — that last one is not configurable, by design.
