A research project, built in public. We invest only our own money. Nothing here is investment advice.

Live with our own money since 26 Oct 2026

The portfolio that gets better as AI gets better.

AI will manage most of the world’s money. Tavrise is where we prove it, in public: frontier AI models research every company on B3 and challenge each other’s conclusions, a person signs every decision, and our own money goes in first. As the models improve, so does Tavrise.

Conviction, with proof.

We believe AI research already beats research done by people alone. Belief isn’t proof, so we put our own money behind every decision, seal it before we trade, and publish every result. Track records written after the fact are worth nothing; this one can’t be edited.

01 · Our money, in the open

Every position, down to the share.

What we bought, when, at what price, and how it is doing, including the cash.

02 · Our reasoning, readable

A summary, or the full study.

Every company has a short version of why we own it, and a comprehensive view with every metric we track.

03 · A record nobody can rewrite

Sealed before we trade.

Each decision gets a time-stamped fingerprint before the order goes out, so it can’t be changed later without it showing.

Six portfolios. R$ 20,000 each.

Each makes money a different way, at a different speed: cheap quality, lasting income, news, trends, the world outside Brazil and intraday futures. Together they cover the market; apart, they barely overlap.

Quality at a low price

Qualidade & Valor

Profitable Brazilian companies the market is pricing as if things will go badly.

Our hypothesis. Markets overreact to bad news. In a panic, strong companies are sold as hard as weak ones, and they return to fair value when the fear fades.

The science behind it

  • Value and quality premiums across dozens of markets (Fama and French; Asness, Frazzini and Pedersen, “Quality minus junk”)
  • Investors overreact, then prices reverse (De Bondt and Thaler, 1985)

A win means beating the market and cash.

The index fund anyone can buy and the CDI, measured after our trading costs. Both, not one.

Too early to judge. We show it anyway.
