Prepify is making high-end, adaptive, online SAT prep free for students anywhere by charging universities for personal introductions to top admissions candidates on the platform. Thousands of SAT-takers each year can't afford test prep. Millions write off college altogether, unaware of the big need-based scholarships most top schools offer. And colleges still struggle to recruit more than ten percent of their classes from low-income families. It isn't news that the colleges are failing at finding socioeconomically diverse applicants. What's news is that we can change that.
