Let Congress help pay
your subscriptions.

Netflix, Spotify, ChatGPT — around €50 a month, gone before you notice. martora puts a small amount of your money to work and tells you the exact chance it covers that bill this month. The stocks come from what members of Congress are buying: by law, every trade they make is public. Wait, why Congress? →

THE CONCEPT

What do politicians have to do
with your Netflix bill?

  1. 01

    CONGRESS TRADES

    Politicians buy and sell stocks. The people who write the laws invest their own money, and it is perfectly legal.

  2. 02

    PUBLIC FILING

    The law makes them tell everyone within 45 days. Anyone can read it. Almost nobody does.

  3. 03

    MARTORA READS

    martora reads all of them, the day they land. That is the boring part, and it is already done.

  4. 04

    MODEL FILTERS

    Then it throws most of them away — copying every politician loses money. Only the trades that make a portfolio stronger survive.

  5. 05

    A FEW STOCKS

    What's left is a short list of stocks you buy at your own bank. martora never touches your money.

  6. 06

    PROFIT → YOUR BILL

    In a good month that list makes a profit. Bigger than your subscriptions? That month the bill covered itself. Not every month is good — so we show you how often it works.

THE LONG VERSION, CATCH INCLUDED → Ten years of backtest, and the ceiling we don't hide

WHAT'S BENEATH

Three products. One engine.

You start by trying to cover part of the costs you already have. You learn by watching the people who have to file. You refine your own strategy when you want the controls. Each one stands on its own page, with its own price of admission.

01

Coverage Plan

The starting point. List what you pay every month, say how much you want to put to work, and get the probability that the portfolio's P&L covers it — ceiling and bad months included.

  • Your bill, not an abstract chart
  • Monte Carlo over thousands of months
  • The capital the odds you want would cost
SEE THE NUMBER → 02

Social Trading

Then you want to know who to follow, and what they actually do. Every filing from 55 tracked members, parsed the day it appears, with the model's verdict attached.

  • Alerts by email and push
  • Full trade history per member
  • Model verdict on every trade

Asset Allocation

For when you want full control. A modified Markowitz model turns those filings into weights — and the same optimizer runs on a portfolio of your own, with no member attached to it at all.

  • Three-stage institutional pipeline
  • martora score, 0–100, on every member
  • Plan your own portfolio, free of Congress
