The Decision Operating System for investment teams

Know what changed. Know why it matters. Remember every decision.

LyraMind monitors the beliefs behind your portfolio, connects new evidence to the assumptions it affects, surfaces the changes that require human judgment, and builds a decision record around what LyraMind proposed and what your team decided.

Source-grounded reasoning Human-controlled decisions Institutional memory

Working with a small number of design partners. We publish what is built and what is not.

A morning, compressed 240-position simulated benchmark
240positions monitored
639active assumptions behind them
57developments arrived overnight, before relevance
11judgments require attention

Most monitored positions had no decision-relevant change.

That last line matters as much as the first. A product that only ever shows you problems gives you no way to know whether it looked at the rest. Each line above counts a different kind of thing: positions, assumptions, developments, judgments, so they are a sequence, not a sum.

Simulated benchmark output, not client data. These four figures come from the scale benchmark run over a 240-position book generated by proof.synthbook. The compression is computed, not authored. But the book itself is invented, so this is not a customer's book, not observed assets, and not a performance claim. The figures under hidden belief concentration come from the same run.

Ask about a position.

Type a question the way you would say it. The answer comes back in the same shape every time: the assumptions behind the position, their state, and what touched them.

The walkthrough

Eight steps, in order.

A guided tour of what LyraMind does with one company, one belief and one filing, taken one idea at a time. Open the first step and scroll to see it in action: each page brings the next one into focus as you reach the end of it.
