Open core

The operating system for multi‑strategy funds.

It runs on your quant’s machine, against your own data, and records every experiment as it happens. The portal is where that work becomes a decision, a position, and something your investment committee can sign.

Who it is for

Three doors, one system.

A fund runs on work that rarely meets. Research happens in code. Decisions happen in conversations. Reviews happen from memory, weeks later. The gap between them is where reasoning gets lost and where nobody can afterwards say why.

The quant

pip install

Nothing about how they work has to change.

  • Their language, their libraries, their data, on their own machine.
  • It runs the experiment they were going to run anyway, and counts how many versions they tried.
  • Every run is written down as it happens, including the ones that failed.
  • It is allowed to say the idea does not hold up. That is the reason to run it.

The PM

the portal

One place to judge the work and turn it into a position.

  • See what was tried this week, on what data, and what came back.
  • See what is live, what changed, and what needs an answer today.
  • Size against your own limits and your own record, not today's confidence.
  • The reason for the size is kept, not just the size.

The CIO

a packet

The review writes itself out of work already done.

  • What each sleeve holds, against the limits you set for it.
  • Which limits were hit, what you decided, and why.
  • A pack for the committee and for diligence, built from evidence already collected.
  • Every number arrives with what it was based on attached.

Open core

The engine is free. Always.

Everything that computes a number runs on your machine, offline, with no account, forever. We do not put the tests that keep you honest behind a paywall, because a research tool that hides its own rigour is not one.

pip install alphaengine

Yours, free, offline

  • The whole engine: every statistic, every test, every correction.
  • Runs your parameter search and counts the versions for you.
  • Writes a study file to your own disk that still opens in two years.
  • No account, no key, no network call on import.

the platform

What one laptop cannot do

  • It persists. Runs, studies and decisions stop living in a notebook.
  • It crosses to another person. Your PM can judge the work without rebuilding it.
  • It adds up over time. Weeks and months become a review, a letter, a diligence pack.
  • It holds the fund together: several sleeves, one set of limits, one record.

A study written on a laptop with no account opens unchanged in the portal. See what a plan costs.

What it replaces

One system instead of five.

Most investment processes are held together by hand. The work is real, but it lives in five places, and the record exists only if someone remembers to write it. We make the process itself the software.

The spreadsheet where the idea gets written up

Ideas are captured in one shape, so nothing gets left out.

The notebook where someone checks whether it works

The test runs the same way every time, and it is allowed to say no.

The ideas that did not work, which nobody wrote down

Every attempt is kept, so nobody spends a week rediscovering last quarter's dead end.

The sizing conversation that happens from memory

Size comes from your limits and your record, and the reason is kept with it.

The scramble before a review

The record is already written, because writing it is how the work gets done.

How it works

Five steps, run the same way every time.

Not because process is virtuous, but because a process you run identically is the only kind you can learn anything from.

  1. 01

    Structure

    Write the idea down properly

    What has to be true, what it is worth if you are right, what you lose if you are wrong, and the dates that settle it.

  2. 02

    Test

    Find out whether it holds up

    It runs against its own history and corrects for how many things you tried. Most ideas that look good do not survive that. Which is the point.

  3. 03

    Size

    Put on the right amount

    Against your limits, and against how your calls have actually paid rather than how confident you feel today.

  4. 04

    Watch

    Know when something changes

    The system holds what you said would change your mind, and tells you when it does.

  5. 05

    Record

    Keep proof you can hand over

    Every decision is time-stamped with what you knew when you made it. Nothing is edited after the fact.

Closed positions feed the next one. As the record builds, the system learns what your conviction has actually been worth, and sizes to it.

The record

Proof you did what you said you would.

Diligence does not ask for your returns. It asks how you decide, whether you follow your own rules, and whether you can show it. That record builds itself here, out of work you were doing anyway.

  • Written before, not after

    What would change your mind is recorded at entry, so the exit can be checked against it.

  • Frozen at the moment of the call

    Each decision keeps what you knew when you made it. Later edits are not possible.

  • Shareable without exposure

    Hand someone the reasoning and the record behind a revocable link. Never your positions, never your data.

    Tested and passed. Sized at half the cap. Two dates to watch.

    Did not pass. Held at a starter size and flagged for review.

  3. ClosedRate cut steepener2026 05 30

    Reached the level written down at entry. Closed on the rule, not the mood.

Illustrative. Not investment advice.

Boundaries

What we do not do.

We are not an accounting system

No positions of record, no valuations, no reconciliation, no NAV. Your administrator owns everything after the trade. We sit before it, on the decision.

We do not touch execution

The platform never places, routes or manages an order. It can hand your systems a ranked list; it will never send a share count anywhere.

We are not the source of your edge

We do not invent ideas or hand you names you did not bring. We tell you whether the idea you have holds up, and stop you trading the ones that do not.

We do not keep your data

Your numbers run through the system and are discarded. Nothing to leak, and no licensing to untangle between you and your own data.

Start with the engine. It costs nothing.

Install it, point it at your own data, and see whether your last good idea survives being counted properly. The portal is there when the work needs to reach somebody else.
