James Montier, one of the most respected researchers in behavioral finance, documented something uncomfortable: when you teach investors about cognitive biases, their behavior barely improves.
Knowledge isn't the gap. The gap is what happens in the moment — when you're watching a position drop and every instinct is telling you to do something. When a stock is running and sitting out feels unbearable. When you've been wrong for six months and you need it to come back.
In those moments, knowing you're prone to loss aversion doesn't help much.
What helps is a pause. A question. A calm voice that's seen this pattern before.
Gertie was built to be that voice.
Not an advisor. Not a dashboard. Not another way to analyze your portfolio.
A companion — the kind that walks beside you through decisions, asks the right questions, and helps you see yourself clearly as an investor.
We believe most investors are capable of making good decisions. They just need something that meets them in the moment, before the click — not after, when it's too late to do anything but learn from it.
What we believe.
- 01 Behavior matters more than stock-picking for most investors. The research is overwhelming on this — yet almost every financial tool is built around the portfolio. Nobody built the tool for the other side of the equation.
- 02 Your brokerage profits from trading volume. We don't. Our interests are aligned with yours: better decisions mean you keep coming back, not more clicks.
- 03 A companion relationship is worth more than a feature list. The question we're trying to answer isn't "what analytics do investors need?" It's "what does it feel like to have a steady, thoughtful presence alongside your decisions?"
- 04 Sustainable beats viral. We're bootstrapped by choice. We'd rather build something that earns trust slowly than something that grows fast and hollows out.
Where we are.
Gertie is an independent, bootstrapped product. We're not a brokerage. We don't profit from your trading volume. We don't manage your money.
We're currently in private beta with a small group of self-directed investors — people who already suspect their emotions cost them money and want help catching that in real time.
The product is still being shaped by the people using it. If you join now, you're not getting a finished thing. You're getting something built with you.
