Learn a whole field in a couple of hours.
Interactive courses you can touch. Drag the models, watch the ideas move, and leave with a plan for Monday — not a stack of notes.
Business
Think like an owner. The five parts of any business, pricing, cash, attention, and the one bottleneck holding you back — taught by dragging the models, not reading about them.
System Design
Scale from one server to millions — estimation, caching, sharding, quorum, fanout, and full walkthroughs of real systems, taught by running the simulations yourself.
Trading
From chart literacy to a professional routine: trader psychology, classical patterns, indicators, the Triple Screen, and the 2% risk rule — taught on live charts you drive yourself.
Marketing
Earn attention without an ad budget: positioning, offers, hooks, and channels that compound.
Product & Startups
From idea to something people pay for: validation, MVPs, and the build-measure-learn loop.
Sales & Persuasion
Turn interest into paid: listening, risk reversal, and pre-answering every objection.
Money & Finance
Survive on what you keep: margin, cash flow, unit economics, and the numbers that lie.
