  • Packaging optimization for cost and sustainability
  • Delivery time predictions (95% accurate)

SignalWire

Programmable voice infrastructure powering SusTern's AI voice agents — enabling real-time supplier calls, automated RFQ follow-ups, and voice-driven procurement workflows.

  • Real-time voice agents for supplier outreach
  • Automated RFQ follow-up and negotiation calls
  • Low-latency, carrier-grade voice reliability

Why These Integrations Matter
