How it works

A pipeline from signal to decision

Every position runs the same disciplined path — quantitative first, qualitative second, risk-checked always, and new positions never opened without your sign-off.

  1. 01

    Screen

    Factor models rank a broad universe on value, quality, and momentum — point-in-time, with no lookahead.

  2. 02

    Reason

    A Gemini pass digests the news, then Claude reads the fundamentals and digest to make the qualitative call.

  3. 03

    Protect

    A deterministic risk overlay sizes positions, sets stops, and trips a drawdown circuit breaker. Rules, not vibes.

  4. 04

    Decide

    You review and approve new buys before they're placed. Risk reduction — trims, stop-outs, and the drawdown breaker — acts automatically, so protection never waits on a click.

The approach

Built like an investor would build it

Opinionated where it matters, transparent throughout, and engineered so the process — not a hunch — drives every trade.

Hybrid quant → LLM selection

Factor screens do the heavy lifting; frontier models add the judgment a pure quant model can't.

Mixed-horizon sleeves

A monthly-rebalanced core factor sleeve paired with a weekly tactical sleeve for shorter-term moves.

Deterministic risk overlay

Per-position sizing and stops with a portfolio drawdown circuit breaker — applied the same way every time.

Point-in-time backtesting

Walk-forward testing with Brinson attribution, so you can see where return actually came from.

Approvals dashboard

A signals queue you triage and approve, with positions, decisions, and P&L tracked in one place.

Paper-first & encrypted

Paper trading until a strict promotion checklist passes. Broker credentials are envelope-encrypted at rest.
