Stripe Startups Build Day NYC
Join the Stripe founder community for a day of hands-on building and coworking with the Stripe team. Whether you’re looking for a chance to connect with other founders, 1:1 guidance from the Stripe team, or just a change of scenery, we’d love to have you join.
Build Days
Build Days are a choose-your-own-adventure format, so you can optimize this time to get the most out of it, whether you’re already building on Stripe or just getting started. Plus, get lunch, coffee, and swag on us.
We’ll kick off with a fireside chat with Alex Atallah, CEO of OpenRouter and former CTO of OpenSea. As an API router for AI builders, OpenRouter has seen massive adoption, serving 4M+ users and processing 500B+ tokens daily. Alex will walk us through this hypergrowth journey, offering practical advice on how to build and scale a company in the AI era.
You’ll also get to see demos of Stripe’s latest products directly from the product teams, so you can leave with insights on how to monetize your AI product, build multisided marketplaces, scale in global markets, and more.
Why attend?
Whether you’re already building on Stripe or just getting started, Build Days offer a relaxed and supportive space to build with guidance and connection.
