DFX Intelligence
RIA Intelligence
Registered investment advisers, the advisors registered through them, the capital they report, the private vehicles they run and the people who own them, as a graph with a filing date behind every number. RAUM is what the adviser filed, a move is two registration dates, and a class is a rule you can read.

Mobility scoring is not published yet. The observable conditions this page will draw on once the historical validation is done: tenure, the firm’s own departures and ownership changes, new state registrations, a new adviser entity with this person on Schedule A, and colleagues’ moves. Until precision and lead time are measured on known moves, no label is printed. Read the methodology.
