• Several of these "guides" attend CU Boulder and Colorado State University.

By the numbers: About 500 students across nearly 200 universities are currently on the platform. Biscotti told Town & Country she ultimately aims to have guides in all U.S. universities.

How it works: Campuswink users can filter for guides online by university, major, hometown, interests, religion and more.

• A 30-minute video call costs $45, a package of three calls costs $120 and an in-person tour of up to two hours costs $150. Student guides pocket most of the fees.

Zoom in: CU Boulder guide Keala M. (class of 2027) pitches herself as an out-of-state, first-generation college student who works while attending school.

• In her Campuswink profile, she writes about leaving her sorority after deciding Greek life wasn't for her.

Here are the most common questions prospective students ask, Biscotti told Town & Country:

• "What do you wish you'd have known about this school?"
• "Would you still come here if you could choose again?"
• "How did you find 'your people?'"
• "Is it hard to get the classes you need to graduate, and can you graduate on time?"
• "If I don't join a fraternity or sorority, will I still have fun?"

The bottom line: The college brochure won't tell you what to wear for rush or which dorm is the loudest.
