The Builder Series Returns to the Rooftop for Its 20th Founder, Investor and Operator Night

The Builder Series: Founder, Investor & Operator Nights returns to New York on October 22 for the 20th edition of its rooftop mixer. The room is built around founders, operators, investors, and advisers meeting before an introduction has to carry the pressure of a formal pitch.

Dylan Oriundo is the named host. The Builder Series describes a program that moves from concierge check-in and open networking into food, group introductions, founder spotlights, and interviews. Registration is paid and approval-required, and the exact address is released only to registered attendees.

Why this room matters now

Networking events are often measured by how many people enter the room. The more useful question is whether the room gives the right people enough structure to find one another.

The Builder Series says attendees may receive one to three warm introductions and that selected founders can use the spotlight portion to explain what they are building and what kind of support would move the work forward. That structure matters because a founder raising capital, an operator solving a hiring problem, and an investor searching for a specific market signal can attend the same event without naturally crossing paths.

The organizer publishes community and prior-event metrics across attendance, company stage, sector mix, assets under management, and check size. Those figures are organizer-reported, not independently audited outcomes. The October 22 room will be judged by what continues after the rooftop empties: the introduction that becomes another meeting, the operator who becomes useful to the build, and the founder whose story reaches the person prepared to act on it.

What the evening includes

• Concierge check-in and open networking
• Food, group photos, and community announcements
• Founder spotlights and short interviews
• Organizer-facilitated warm introductions
• A private New York location shared after registration
