Who to call

the organisation, the role and the published line, with the filing or website that published it; revealed to signed-in accounts

The firm's published line

Revealable: 1 business phone (Form ADV), 1 office address (Form ADV), 1 website (Form ADV) · as of 2026-09-13

Also named here, with no published line of their own (reach them through the firm): Benjamin Fereidoon Mahdavi (Managing Partner), Kabir Dev Masson (Chief Compliance Officer & General Counsel), Christopher Michael Capozzi (Chief Financial Officer), LEE Charles Linden (Managing Partner), Matthew Zeller Humphrey (Managing Partner), Griffin Gates Howard (Head Of Capital).

Who to call is the organisation, the person's role and the line they published themselves: a business phone, office address, website or profile link from Form ADV, Form 13F or their own website, with that source named on every value. The counts above are what a reveal returns; a personal email is rarely published, so most reveals are the firm's line. Never data bought from a provider, never anything personal. Reveals by plan
