An AI agent that manages your brokerage portfolio

You pick the ideas.
Prometheus runs the portfolio.

Tell Prometheus which stocks you believe in and how confident you are. It works out how much to own of each, then buys, trims and rebalances your brokerage account for you, automatically. You can approve trades, override it or pause it any time, and every action is logged.

How it works

Set it up once. The agent handles the trading from there.

1Connect your brokerage

Accept once and sign in on your brokerage’s own page. It opens a separate account for the agent, funded with only what you choose.

2Add your ideas

For each stock, share your reasoning, your price targets and how confident you are. Paste notes or drop in files and Prometheus fills in the rest.

3The agent manages it

It sizes every position, places the trades and rebalances during market hours. You get the reports and the final say.

Built like an institutional desk

The sizing discipline hedge funds use, in an app on your phone.

Institutional sizing, built in

Position sizing and risk limits come prebuilt with the conviction-weighted method professional funds use. Every setting is configurable, and you’re guided through each one.

Connects to your brokerage in a minute

Accept once and sign in on your brokerage’s own page. The agent trades only the separate account you fund, and never sees your password.

You stay in charge

Set any position to approval-only, lock or freeze a size, force an exit, or pause everything with one switch.

Research that expires

Drop PDFs, notes and screenshots into the research chat. Theses older than 180 days get sold, so stale ideas can’t linger.

Reporting you’d show a committee

Performance vs the S&P 500, drawdown, exposure, monthly returns, a holdings statement and a full trade blotter.

A tamper-evident audit trail

Every agent action, analyst update and human override is chained by SHA-256 and can be verified in one click.

Three ways to pay

Monthly, yearly, or a small fee on each trade the agent places.
