Starling could be leaving ~$54,400,000 in processed value on the table every year

Stunt Double’s 2027 agent-traffic model projects 34% of account opening and transaction initiation sessions in the finance sector will be initiated or completed by AI agents[1][2]. Starling currently scores 68.0 on the Stunt Double Index[3], with a 32-point gap to the ideal agent experience (100). The loss figure below applies that gap to the projected agent-driven slice of a typical annual processed transaction valuebaseline for this sector — it is a directional estimate, not a measured conversion rate.
