Train like a quant. Daily.
Lemma is the focused, no-fluff prep app for quantitative interviews — built for students and grads targeting Jane Street, Citadel, Optiver, Two Sigma, and the rest of the trading-firm gauntlet.
WHAT'S INSIDE WITH YOUR SUBSCRIPTION
• Daily sprints — bite-sized timed sets of mental math, probability, combinatorics, expected value, and market-making problems
• Per-category ELO — your skill is tracked across 10 disciplines, from Novice to Expert
• Adaptive difficulty — problems chosen to keep you at the edge of your level, not above or below
• Hints + step-through solutions — get unstuck without giving up
• Streaks, XP, leagues — habit loops without the noise
• Achievements — unlock as you grind
• Leaderboard — see how you stack up
WHO IT'S FOR
• CS / math undergrads applying to trading firms
• Recent grads prepping for technical interviews
• Self-learners who want a daily quantitative-thinking habit
• Anyone curious about how trading interviews actually feel
WHY LEMMA
We strip out the gamified clutter and keep what matters: hard problems, fast iteration, real numbers on your progress. The interface borrows more from a Bloomberg terminal than a typical mobile game — monospaced metrics, hairline borders, dark by default.
Most prep books drown you in 800 pages. Most courses lock you in for months. Lemma is 10 minutes a day, sharpened every day.
