Four principles that shape every release.
Built for every market
20+ languages out of the box. Strict locale-locking so your agent never breaks character.
Best-in-class AI
Modular pipeline — swap models without re-training. Always grounded in your knowledge base.
Enterprise-grade privacy
Zero-retention model partnerships, GDPR-ready, AES-256 at rest, TLS in transit.
Train once. Deploy everywhere
One knowledge base powers chat, web voice and phone calls — no duplicate config.
How we work.
Ship a working agent in under 10 minutes — that's our north-star metric.
Agents say 'I don't know' rather than guess. End-users always know they're talking to AI.
No vendor lock-in. Move between plugin, snippet or API any time.
Pay-as-you-go, no surprise renewals, credits never expire.
