What's the story behind your product?

The founding team had spent years building voice automation for big companies, helping them reduce support costs and improve customer experience.

Voice AI & Natural Language Processing (NLP) Powered by large language models (LLMs) and speech-to-text / text-to-speech systems Enables natural, human-like conversations and intelligent FAQ handling Supports multi-language interactions (e.g. English, Spanish, French, German)

Telephony Infrastructure Built on top of scalable cloud communications platforms like Twilio or Plivo Handles call routing, voicemail fallback, number provisioning, and SMS delivery
