About
Kim scored a perfect 1600 on the SAT and graduated summa cum laude from Dartmouth. She went on to work as a software engineer at Apple and Airbnb, building products used by millions. But her path to starting Sharp began with a much smaller problem: helping one student.
The summer before her cousin applied to college, his family had already spent thousands on a private tutor and hundreds more on Acely, an online prep platform. His score barely moved. Kim offered to help, and within a month of working together, he improved by 160 points and got into Rice, his dream school. What she did wasn't complicated. She figured out exactly which skills were costing him points, drilled those relentlessly until he had them down cold, and kept him on a schedule so the work actually got done. When tutoring additional students, she found the same pattern held: the students who improved most weren't studying the most hours. They were the ones whose practice was targeted at their actual weaknesses, who understood why they got questions wrong, and who had someone keeping them accountable.
Sharp is built on that pattern. In education research it's called mastery learning: identify a specific gap, work on it until it's solid, then move on. Most prep courses skip this entirely, giving every student the same curriculum regardless of where they're struggling. Sharp's AI does the opposite, adapting to each student's weaknesses using practice content written by expert SAT tutors who know exactly what the test looks like. But the AI is only part of it. Sharp is designed to work alongside human tutors, not replace them, handling the repetitive skill-building so tutors can focus on strategy, motivation, and keeping students on track. For students working on their own, Sharp provides that same structure: clear goals, a focused plan, and the confidence that their target score is something they can actually reach.
