Buying a stock keeps getting easier. Knowing what to buy, and why, is still the hard part. Trimmy gives you a desk before it asks you to become an investor.

  1. Short, playable workdays. Read the figures, pin the evidence, make the call, then see what you missed. The first 20 assignments ship with the app, and new ones publish through the API.
  2. Practice and real money never look alike: purple for paper trading, green for your wallet, everywhere in the app.
  3. Real trades go through the user's Privy wallet and Jupiter. The server checks each transaction before the user signs and confirms the result on-chain after.
  4. The website is a scroll film: a flythrough of Wall Street's history, from the war debt to the trading floor, built and timed by hand.
