Research & Methodology

Six papers, one subject.
A reading map for late-stage private-market pricing infrastructure.

Late-stage private markets increasingly run on a single number: the mark. For that number to carry institutional weight, it has to be both reliably produced and able to survive scrutiny. This set covers that subject from two orthogonal angles, with an open quality standard above both. Each paper answers one question, shown in quotes. To navigate, start from the question you need answered.
