QA for your Bland agents

Pathways define what your agent should do. Zelto grades what it actually did — on every production call — and turns recurring failures into ranked, fixable Findings.

What actually breaks on Bland in production

Dashboards show you that calls happened. They don't show you the calls that quietly failed — and those are the ones that cost you customers.

Pathway dead-ends

Callers reach a node that doesn't handle their answer, and the conversation stalls or loops. One dead-end node can quietly eat hundreds of calls. Zelto clusters them into a single Finding ranked by call volume.

Transfers that never happen

The caller asks for a human, the condition doesn't trigger, the agent keeps going. Nobody complains to you — they just don't call back. Grading real calls is the only way to see it.

Prompt and pathway drift

Small edits accumulate. Zelto grades every call after every change, so a regression introduced on Tuesday is a Finding by Wednesday, with example calls and a drafted fix.

Failures that sound fine

The agent stays fluent while giving a wrong price, booking the wrong slot, or skipping a required disclosure. Latency and completion metrics all look green. Only conversation-level grading catches it.

How Zelto works with Bland

  1. Connect

    Connect Bland to Zelto and every completed call flows in with its recording, transcript, and metadata — or send calls through one REST call (calls.ingest) from your post-call webhook.

  2. Zelto listens and diagnoses

    Every production call is graded against a rubric Zelto auto-learns from your traffic — your domain, your language, your definition of a good call. No setup, no scorecard to write.

  3. Findings, with the fix drafted

    Calls that fail for the same reason are clustered into one Finding, ranked by volume, with example calls, a drafted prompt fix, Slack alerts, and an optional Linear ticket.

Production traffic, not simulations.

Simulation tools grade synthetic conversations against scenarios you wrote. Zelto grades what actually happened with real callers on your Blandagents — because that's where the failures that matter live. Most teams are integrated in under 15 minutes.
