Executive Summary
Miyagi Labs is a YC W25 seed-stage startup building an AI-native SAT/ACT prep platform, founded in early 2025 by two MIT CS graduates with $500K from Y Combinator. The market is real — US digital SAT/ACT prep is a $1.5–2.5B addressable segment growing at ~7% annually, with meaningful AI tailwinds — and the digital SAT transition in 2024 created a genuine opening for AI-native players. However, every single traction claim on the company's website (10,000+ questions, 2× speed improvement, 90%+ satisfaction) is self-reported with zero independent corroboration, the company appears to have pivoted from a different core product just months ago, and its most direct competitor is Khan Academy — which is free, College Board-endorsed, and already AI-powered. The single biggest risk is not execution, it's structural: Miyagi is asking students to pay for something the world's most trusted education nonprofit offers for free, with official backing from the SAT's owner.
