Free Online Appointment Scheduling Soft… could be leaving ~$1,992,400 in new ARR on the table every year

Stunt Double’s 2027 agent-traffic model projects 34% of trial, signup and plan selection sessions in the SaaS sector will be initiated or completed by AI agents[1][2]. Free Online Appointment Scheduling Soft… currently scores 70.7 on the Stunt Double Index[3], with a 29-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 recurring revenuebaseline for this sector — it is a directional estimate, not a measured conversion rate.
