AI Voice & Calls
We design, build and harden Vapi voice assistants, custom tool calls, multi-assistant squads, telephony, CRM and calendar integrations, so your demo becomes a system you can trust with real customers.
The short version
Vapi makes it fast to get an assistant talking. Getting it to behave reliably on thousands of real calls, with low latency, clean interruptions, correct tool calls, sensible fallbacks and clean data in your CRM, is where most projects stall.
We’ve built enough Vapi assistants to know where they break. We choose the model, transcriber and voice for your latency and cost targets, write server-side tools with proper error handling, and put monitoring in place so you know when something changes.
