We built Callee so humans can supervise AI voice agents in real time

Who we are

Callee was born from operators sitting next to AI

Callee started inside busy contact centers where we watched humans wrestle control away from early voice bots. Our team built a stack that lets AI dial thousands of customers while supervisors see the same transcript, KPIs, and segmentation labels instantly.

Now revenue teams, CX orgs, and research groups rely on Callee to recover payments, run outbound prospecting, route inbound support, and host browser-based calls with screen share. We keep humans in charge while AI handles the repetition.

Human-in-the-loop by default

Callee designs every workflow so operators can watch, interrupt, or hand off a call at any moment. Automation never replaces accountability.

Compliance obsessed

We partner with revenue recovery, finance, and healthcare firms. That means shipping guardrails, redaction, and auditability—not just shiny AI.

Operator empathy

Our team sits with support reps, collectors, and researchers weekly. We build the console they actually need: fast search, live audio, instant kick-outs.

Ship fast with real feedback

We release new voices, decision nodes, and integrations every sprint, guided by call data flowing from thousands of Callee rooms across the globe.

Build a voice agent your operators trust.
