Which customers your agent wins. And which it loses.

sparr turns your real conversations into personas and runs them against your agent — live, or before you ship it.

Built from your own conversation data, never generic benchmarks.

Our stance

The average customer doesn't exist. Yours do.

You fix the conversation, not the dashboard.

Audit the agent you've shipped. Rehearse the one you haven't.

On live agents

Audit the agent already serving customers.

Point sparr at the agent serving customers today; in the pilot, we read the conversations that cost you customers together.

Before deploy

Rehearse the version you haven't shipped.

Try a new prompt, model or setup against the same personas, before a single real customer meets it.
