Founders Day
The world’s largest founders-only gathering with high energy, top partners, and real connections at Cable Factory, Nov 18 (Day 0) at 5–11 PM.
Activities
Stage Program
The Founders Day stage features interactive sessions and no-nonsense conversations with experienced founders and operators. These are the kinds of insights you won’t find by searching online—practical, hard-earned lessons shared by people who have actually built. Past speakers include Cal Henderson (Co-founder of Slack) and Jack Mardack (Co-founder of Oyster).
Partner Lounges & Program
We’re making the Founders Day experience even more valuable by joining forces with top-tier partners for curated lounges designed just for founders. Each lounge hosts its own dynamic lineup—from roundtable discussions tackling real-world founder challenges, to speed-dating sessions that spark new connections. Dive into workshops focused on practical skills to accelerate your journey, or join industry-specific meetups to connect with others building in your space. Whether you’re looking to learn, share, or simply vibe with other founders, there’s a space for you.
Networking Area
Looking to meet fellow founders without any pressure? The Networking Area and Founder Arcade are designed for exactly that with relaxed spaces that make meaningful connection easy. Use the matchmaking tool before the event to spot founders you’d like to meet—or just show up and let serendipity do its thing. Drop by the Networking Area for casual convos and spontaneous meetups, or head into the Founder Arcade for classic games and low-key challenges that turn downtime into new connections.
Eat & Drink
Throughout the evening, you’ll find a range of food options available at affordable prices, so you can grab a bite without leaving the action. To keep the good vibes flowing, we’ve reserved a limited amount of free drinks, available on a first-come, first-served basis. Feeling extra thirsty? You can also purchase additional beverages throughout the evening.
