FinLex is the vocabulary and professional education app built for ambitious professionals — analysts, consultants, MBA candidates, and anyone serious about mastering the language of finance and law. THE 10-MINUTE TRADE You already pick up your phone 50+ times a day. Most of those moments end with you closing the app slightly worse off — emptier, more anxious, no smarter. FinLex is designed to replace those moments. Open it instead of the feed. Swipe one card. Finish one lesson. Walk away with something. The reward isn't dopamine, it's compounding knowledge — the kind that shows up later in a meeting, a contract, a pitch. Two ways to learn. Both rigorous. WORDS — Swipe through 5,000+ curated terms. Every card is hand-written, not auto-generated. Each term comes with a clean definition, phonetic guide, part of speech, synonyms, etymology, and a real-world example sentence drawn from how the term actually shows up in deals, filings, and regulation. Learn the vocabulary that matters in your work, not abstract textbook examples. COURSES — Built like an MBA module. Designed for your phone. 15 structured courses spanning corporate finance, valuation, M&A, investment banking, project finance, data visualization, public-private partnerships, and more. Highlights include: - Project Finance — capital structuring, cash flow waterfalls, debt service coverage, risk allocation, infrastructure financing - Data Visualization — chart selection, annotation, small multiples, the level-vs-delta distinction, color for meaning - Public-Private Partnerships — concession structures, BOT/BOOT models, viability gap funding, risk-sharing frameworks Each course is broken into modules, lessons, and short cards you can finish in 5 minutes between meetings. Every lesson ends with a quiz to lock in what you learned. LEVEL UP BY ACCURACY, NOT BY SCROLLING. Your level reflects how well you actually answer quizzes — not how many cards you swiped past. Earn your way up. See your accuracy, your streak, and the count of words you've truly mastered. The whole system is built around one idea: the time you give an app should give something back. FREE & FINLEX PRO Start free with a selection of courses and word cards. FinLex Pro unlocks the full library — every word card and all 15 courses — with a 7-day free trial, then a monthly, quarterly, or yearly auto-renewing subscription.
