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.

Until precision and lead time are measured on known moves, no label is printed. Read the methodology.
