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 is dedicated to real learning, featuring no-nonsense conversations with experienced founders and operators. Expect practical, hard-earned insights you won’t find through a quick online search. These are lessons from people who’ve actually built, scaled, and succeeded.
We’re kicking off the stage program with our first speaker: James Hawkins, Co-founder & CEO of PostHog—with more speakers to be announced soon.
Partner Lounges & Program
Founders Day is the one evening that saves you months of figuring it out.
We’re making the Founders Day experience the most valuable by joining forces with top-tier partners hosting curated lounges designed just for founders. Each lounge hosts its own dynamic lineup—from legal advice clinics to panel discussions tackling real-world founder challenges. Dive into workshops focused on practical skills to accelerate your journey, or join industry-specific meetups to connect with others building in your space.
This year, we're joined by Amazon Web Services (AWS) and Anthropic as our Main Partners, as well as Dottir Attorneys, PostHog, and Stripe as Supporting Partners.
Sign up for the Partner Lounge program here.
Feeling overwhelmed by the packed program and a busy Slush week ahead? Step into the Relaxation Corner—a calm space to reset, refocus, and recharge. With professionals on hand to guide you, you’ll leave feeling centered and fully ready to nail those investor pitches over the next two days.
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.
