Launching an AI voice agent is easier than ever, but validating how it performs under pressure? That's where most teams lose weeks of precious time. Cekura changes that entirely. Cekura.ai is an automated testing and observability platform built specifically for voice and chat AI agents. Instead of waiting for real-world failures to surface problems, Cekura lets you run thousands of simulated scenarios in minutes, testing everything from prompt changes to off-script user behavior and diverse caller personas before a single live call takes place. In this video, you'll see how Cekura compresses the traditional QA cycle from weeks down to minutes using parallel calling and a deep library of pre-built scenarios. Watch how the platform handles edge cases like angry or impatient callers, unexpected interruptions, and compliance-sensitive conversations, all before you go live. You'll also get a look at Cekura's production monitoring capabilities, which track every call for hallucinations, instruction-following accuracy, and conversational quality, with real-time alerts when something goes wrong. Whether you're building customer support agents, outbound sales bots, or specialized tools for healthcare or legal intake, Cekura gives your team the confidence to ship faster without sacrificing reliability. Trusted by companies like Five9 and HighLevel and backed by YCombinator, it integrates seamlessly with platforms like Vapi, Retell, and ElevenLabs. Ready to launch AI agents you can actually trust?
