Built by Telecom Veterans. Powered by Builder DNA.

Jambonz was born out of necessity, not venture capital.
We built it because the platforms we needed didn’t exist. Now, we’re helping voice AI teams build, scale, and ship without compromise.

We Exist to Give Builders Control.

Our mission is simple: empower the next generation of voice AI platforms with infrastructure that doesn’t get in the way.

That means full deployment freedom, AI choice, and predictable scale. No black boxes. No per-minute surprises. Just a platform that works the way you do.

We Believe Control Isn’t Optional

We don’t think real platforms should force trade-offs between speed and flexibility, or between privacy and scale.

You should choose the AI, the call flow, and the speech stack.

You should deploy where you want—your cloud, your customer’s, or your own servers.

You should scale on your terms, not your vendor’s billing model.

You shouldn’t need a telecom PhD to make it all work.

Trusted by Teams Who Can’t Afford to Guess

From outbound AI agents to enterprise CX stacks, Jambonz powers platforms where performance, privacy, and control are non-negotiable.
Used by leaders like Cognigy, Rasa, VAPI.

Powering millions of minutes per month across self-hosted and hybrid environments

Built by Telecom Veterans.
Tuned for AI Innovators.

We didn’t set out to build another CPaaS—we built what didn’t exist: a voice platform that gives you total control, infinite flexibility, and no compromises.

Jambonz is the result of decades building carrier networks, cloud infrastructure, and large-scale voice deployment. Today, we help the teams shaping the future of AI-driven conversations own their stack, ship faster, and scale smarter.

We’re small by design. Senior by default. And obsessed with giving developers and platform builders a better way to build voice.
