TRKR

What is TRKR

Nothing beats a human helped by robots.

TRKR — short for Tracker — builds technology for investors. Our first product is synthetic market data: realistic simulated futures you can use to test portfolios and trading strategies without waiting for history to repeat itself.

How it works </from history to futures>

  1. 01

    Learn from real markets

    The engine trains on twenty years of daily prices for 20 assets — equities, bonds, gold, real estate, sectors, and international markets — together with 7 macro variables like rates, credit spreads, and volatility.

  2. 02

    Simulate alternative futures

    From that history it generates 400 alternative futures, each ten years of daily prices. The simulations shift between calm and stressed market regimes, the way real markets do.

  3. 03

    Check itself against reality

    Every batch is calibrated and scored: in the current dataset, 238 of 258 real risk measurements fall inside the synthetic 5th–95th percentile band. You can inspect these quality checks yourself, per asset.

  4. 04

    Put it in your hands

    Explore the data, build portfolios against every future at once, and point your own AI assistant at the simulations to read them with you.

Methodology

A regime-aware, macro-driven scenario generator that produces hundreds of realistic joint futures for assets and the economy — anchored to today's conditions, calibrated to two decades of evidence, and validated against history before anything ships — so portfolios and strategies can be tested against the full range of markets that could plausibly happen, not just the one history that did.

Why synthetic data?

History only happened once. A strategy that survived the last decade may just have been lucky. Testing against 400 plausible futures shows you the range of outcomes — including the ones that never happened, yet.

Who built this

I built TRKR because I couldn't buy it.

For ten years I ran the portfolios at a multi-family office in São Paulo, answering the same question from clients: is this portfolio safe? The tools I had gave me a probability of success, computed from returns drawn out of one fixed distribution, forever — no regimes, no correlations breaking, no crisis. I never quite believed the number. Neither did the families I was showing it to.

So I built the thing I wanted to use. TRKR generates hundreds of complete alternative futures for real markets, with regimes that persist and asset sensitivities that change depending on which regime you're in — because that is when diversification actually fails, and that is when a portfolio needs testing.

It is also exact about what it isn't: not advice, not real market data, no orders, no assets, and no tool that returns per-path outcomes, so no one can pick the futures they like and call the result a benchmark.

More than four decades across several banks, a fintech and a family office is why this is a product with a feedback button, not a paper.

It's free during the beta because I'd rather have your objections than your money.
