The customer / use case

Higher-ed and bootcamp admissions teams field huge inbound volume during enrollment seasons (Aug, Jan, May). The published 2026 winners are voice agents that introduce the program, qualify intent, and book the human-counselor demo without burning a counselor on every call. Gartner predicts 60%+ of student interactions will be AI-supported by 2026.

FAQ

FERPA — can the agent talk about a current student's record? Only with verified ID&V. Inquiry-stage prospects have no FERPA record yet, so no issue. For current students, CallSphere applies a verification gate (DOB + student ID + on-file mobile OTP) before any record disclosure.

Will it really book the counselor demo on the first call? Yes. TripleTen's Charlotte does this; CallSphere benchmarks 55–65% same-call counselor booking on warm inbound prospects. Cold outbound is lower (25–35%).

International students, multi-language? Native realtime multilingual. Spanish, Mandarin, Hindi, Portuguese, Vietnamese are the most-used in US higher-ed admissions calls.

Counselors — replaced or augmented? Augmented. TripleTen kept its admissions team and used Charlotte to scale marketing without scaling counselors. Same playbook for our customers.
