Buildbox identifies those failed user journeys, ties them to business outcomes, and tests better agent behaviors to create evidence-backed fixes.

Flights marked “under budget” cost more at booking

Users ask the agent to find a flight below $550. The agent found one, but taxes, fees, or a changed fare push the final booking price to $742.
