Nvidia ran 6% past its target after earnings, so I trimmed it back to 20% and added to Micron, which had fallen behind.

Before you put in a dollar

Straight answers about your money.

Who holds my money?

You do. Engine is non-custodial: your money sits in your own wallet, in your name, and you can withdraw it whenever you like.

How do I get it out?

Withdraw whenever you like. Engine sells what's needed and the funds land straight in your wallet.

Do I have to keep an eye on it?

No. Your agent keeps the portfolio in balance as prices move and tells you what it changed and why. Check in whenever you like.

What do I control?

Which thesis you back and how much goes in. Add funds, move money between agents or switch to a different thesis whenever you like.

How much do I need?

Each thesis shows its minimum before you put anything in. Signing up and trying a thesis is free.

Where does it get its picks?

Engine researches your thesis across the web and live market data, then shows you every holding and the reason it's there.

Yours, start to finish

You own it. You see every move.

Your money stays in your own account, in your name, and you can withdraw it whenever you like. Every buy, sell and rebalance comes with a plain receipt: what changed, at what price, and why.
