Also named here, with no published line of their own (reach them through the firm): Amanda Duckworth (Communications Advisor), Lynne Chou O'Keefe (Managing Director), Bruce Broussard (Venture Partner), Frank Williams (Venture Partner), Carolyn Magill (Venture Partner), Chirag Shah (Partner), Michael Wert (Partner), Hong Truong (Principal), Chuka Esiobu (Principal), Garrett Howard (Principal), Karsten Vagner (Head of People), Shannon Knous (VP of Finance & Operations).
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
