Loved by Teams and Developers
Thousands of builders trust our technology to power fast, reliable, real-time experiences.
Founder, Refrens
We turned voice into a programmable, real-time system. We can now qualify thousands of users automatically and route only high-intent leads to sales — something that wasn't possible with manual workflows.
Product Team, Refrens
We built a low-latency Voice AI pipeline that integrates directly with our CRM and sales workflows. It allowed us to move from manual outreach to a fully automated qualification system at scale.
Product Manager, Groww
A developer-friendly platform and responsive team enabled us to go live within a month, achieving ~90% call success with almost zero technical issues.
Engineering Lead, Fi Money
A plug-and-play engine helped us deliver a reliable, high-quality experience without having to build everything from scratch. We still had full control, saved months of development time, and went live with confidence.
CEO & Co-Founder, Talk Your Heart Out
We switched from a major international provider because of the responsiveness to feedback, strong product quality, and better service. The team has consistently been excellent at resolving issues quickly.
Lead AI Engineer, Coala Saúde
The platform has become a core part of our operation. Its reliable real-time infrastructure allowed us to build an automated pipeline that processes conversations quickly and consistently.
Software Developer, Felicity
We were looking for a reliable alternative and found a solution that was quick to set up and cost-effective. The support experience has also been great, and I would definitely recommend it.
Head of Business, Examedi
Our experience has been outstanding. The speed of implementation, personalized support, and significant reduction in call failures have made a real difference to our platform.
Sr. Software Engineer, CoderSchool

Frequently asked questions.
ZeroRuntime is an AI voice agent infrastructure platform for building, deploying, and running production voice AI agents across web, mobile, telephony, and physical devices. The runtime brings the transport layer, agent logic, and voice components together in one optimized system, reducing orchestration overhead and latency. Agents can start on demand without being pre-reserved, making it easier to scale concurrent sessions without managing the underlying infrastructure yourself.
Not necessarily. Start with the no code builder, use ready-to-deploy templates, or work directly with SDKs when you need granular control.
Yes. ZeroRuntime works with multiple LLM, speech-to-text, and text-to-speech providers, so you can configure the stack that fits your agent.
An optimized runtime coordinates speech, models, and audio with less processing overhead and more efficient orchestration across the voice pipeline.
Start with a ready-to-deploy template or configure an agent visually from the dashboard. Developers can also use SDKs for deeper customization and product integration.
ZeroRuntime offers pay-as-you-go pricing for flexible usage. For higher-volume workloads or enterprise requirements, talk to our sales team for a custom plan. See the ZeroRuntime pricing page for details.
