callexWe're building the voice layer for critical operations.
Callex helps critical operations, from clinics and banks to insurers and governments, raise answer coverage with voice agents designed to resolve common requests.
Our mission
Callex was founded in 2025 in Israel. The most important calls in the world still meant hold music, missed connections, and overwhelmed teams. We set out to change that, to make production-grade voice AI the default for every organization that runs on the phone.
We’re a small, senior team of voice, machine-learning, and infrastructure engineers who care about the calls that can’t afford to fail. We’re early, and building for the long run.
What we value.
Production over demos
A flashy demo is easy. We obsess over the calls that happen at 2 a.m., at scale, when it counts.
Trust is the product
Security, accuracy, and reliability aren't features. They're the reason critical operations choose us.
Customer obsession
We measure ourselves by resolved calls and happier callers, not by tickets closed.
Move with urgency
Voice AI is moving fast. We ship, learn, and improve in days, not quarters.
Leadership.
We’re hiring.
A small team taking on a big problem. We’re growing across engineering, go-to-market, and design.
