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 website (Form ADV), 1 work email (firm website) · as of 2026-09-17

Also named here, with no published line of their own (reach them through the firm): Jonathan P. Gertler (MANAGING DIRECTOR), Walter Gilbert (VENTURE PARTNER), Stephen Liu (VENTURE PARTNER), James Lousararian (Shareholder), Laura Niklason (VENTURE PARTNER AND PRINCIPAL), Tony Lyons (MANAGING DIRECTOR - INVESTOR DEVELOPMENT), Chris Thompson (KEYSTONE PARTNER), Marc Goldberg (CO-FOUNDER AND MANAGING PARTNER), Jeffrey Barnes (MANAGING DIRECTOR), Tom Buttacavoli (MANAGING DIRECTOR), Jonathan Cohen (KEYSTONE PARTNER), Peter Feinstein (CO-FOUNDER AND VENTURE PARTNER).

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
