Handled our peak support call volume without dropping a single lead.
No-code agent builder actually works as advertised.
Natural sounding voice synthesis.
Setup with legacy SIP trunks took some tinkering.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Design voice agents for any call workflow visually, or start from ready-made templates in the App Library, and rehearse conversations in the Playground before anything goes live.
Handles outbound lead qualification, inbound intake, customer support, appointment booking and debt collection follow-ups, replacing repetitive L1/L2 questions where a human adds little.
The platform sits behind your existing SIP trunk and connects to VICIDial, Convoso, Five9, Genesys and similar systems, so nothing has to be ripped out or migrated.
Conversations keep sub-second latency with natural interruption handling and accurate answering machine detection, and escalations transfer live to a human with full context and a call summary on screen.
You own access to all transcripts and recordings, with automated scoring against your own rubric, live supervisor monitoring and dashboards on containment, transfer rate and disposition mix.
SigmaMind is a no-code voice AI platform built for teams that live on the phone. Rather than adding another dashboard, it deploys AI voice agents that call and answer like a real person on top of the telephony you already run. The agents handle the repetitive work that consumes calling floors: no-answers, wrong numbers, unqualified leads and L1/L2 questions about hours, pricing, order status and refunds.
The use cases span outbound lead generation and qualification, inbound lead intake, end-to-end customer support, appointment booking and regulated collections follow-up, with published case studies from insurance, media, multi-brand retail and e-commerce. Reported outcomes include a cost per contact dropping from $8 to roughly $1 in support, $0.50 versus $8 in collections, 8x more dials than human agents, a 75% lower cost per qualified lead, and first response times cut by 50-71%.
Operationally, SigmaMind is designed to fit rather than replace. It sits behind your existing SIP trunk and connects to dialers and contact center platforms such as VICIDial, Convoso, Five9 and Genesys. Agents are built visually or from templates, tested in a Playground, and monitored through analytics, transcripts, recordings and rubric-based QA scoring. Conversations hold sub-second latency with natural interruption handling and answering machine detection, and escalations transfer warm to a human agent who sees the full context before saying hello. Pricing is quoted through sales rather than published online.
Run qualification calls at a volume a human floor cannot match, then hand warm, qualified prospects live to closers with the full context on screen.
Resolve order status, refund and account questions end to end, keeping wait times down during peaks and routing anything complex to a human with a summary ready.
Follow up consistently and compliantly on outstanding payments while keeping cost per contact far below a human floor.
Cover inbound booking, lead intake and after-hours calls so enquiries stopped outside business hours turn into scheduled appointments instead of missed revenue.
