Popperian · AI-native trading research

We don't build strategies.
We build the loop that finds them.

Popperian is an investment research product: a self-improving research loop, enforced through AI.

01 — thesisone idea

Built around a research loop, enforced through AI.

Find a question, form an understanding, write it as a strategy, watch the result, let the feedback improve the next round. AI makes recording, testing and updating part of the work rather than a good intention.

02 — layerstaste → harness → strategy → prediction

What are the layers?

01

Taste

Which changes deserve attention, and which questions deserve research budget.

02

Harness

The data, tools and working mechanisms that organize research. People and AI both go through it.

03

Strategy

Understanding written as executable rules: read information, form a prediction, decide what to do.

04

Prediction

A testable judgment made at a point in time. It cannot be rewritten after the outcome arrives.

03 — loophow it learns

Everything is a learning problem.

Not just the strategy. The evaluator, the generator, the taste and the harness each have an objective, data, feedback and a rule for how they update.

05 — principleswhat we believe

What we believe.

  1. P-01

    Research can recurse. Markets won't restart for you.

    History can be recomputed. Evidence can't be copied.

  2. P-02

    Put numbers on uncertainty, then let reality grade them.

    A probability per scenario, filed before the outcome.

  3. P-03

    Design for the models of six months from now.

    Scaffolding should be easy to delete.

06 — peoplewho finds a place here

Different disciplines, one loop.

Scientists

Make the loop improve itself

Where self-improvement and RL apply in research, and how a person's taste becomes a model.

Engineers

Build the workbench

Clear modules and contracts. Data, tools and evaluators that can be versioned and judged.

Traders

Bring the real problems

Say what you need. Write your rules down, run them, iterate on results.

Capital partners

Understand before you allocate

Every strategy comes with its basis, conditions and risks.
