How we build

We build ventures ourselves rather than backing them from the outside, and we hold our own claims to the standard we would expect from anyone asking for capital.

Built in-house
The founders design and build every project themselves, from the architecture to the tests.
Evidence before claims
Pre-registered tests, append-only research records and mutation-tested integrity checks. A project figure appears here only if it can be traced to its source.
Corrections in public
When a result does not hold, we say so on the page where it appeared. X-Quant’s withdrawn metrics are the clearest example.
