sip.coach, the AI sales coach that listens

sip.coach is a production voice-AI product by Beyonetix. Sales teams use it to practise sales conversations by voice with an AI coach and get instant feedback. For us it also serves as proof of what a finished, sovereign voice-AI application looks like. We build applications like this for you as well.

What it is

Selling is learned by speaking, not by reading

Classic training is expensive, happens rarely and barely scales. With sip.coach, anyone can practise whenever they want. The rep picks a scenario, say cold calling, objection handling or a price negotiation, and then holds a conversation with an AI counterpart that responds to her voice in real time.

After the call comes a structured evaluation, covering talk-time, objection handling, questioning technique and closing orientation among other things. What used to be gut feeling can now be measured and practised deliberately.

Sovereign architecture

Built on a stack you control

Beneath sip.coach sits the same architecture we use for your application: a FastAPI backend, a modern Angular/Ionic app, Keycloak for single sign-on and an Odoo connection for billing and administration. The voice pipeline (recognition, dialogue, synthesis) and the LLM run either EU-hosted or entirely self-operated.

Sensitive conversation content stays under your control. No US model is required, operation is GDPR-compliant and, on request, on-premise.
