Arbitrum (@arbitrum): Inside Arbitrum Founder House London

Inside Arbitrum Founder House London A new generation of founders is building businesses that will power the programmable economy. That's why we're bringing together @RobinhoodApp Chain, @awscloud, @Offchain, Arbitrum Foundation, and industry leaders to help teams accelerate from idea to launch at our in-person builder program - Founder House London. From July 10–12, selected teams will receive hands-on product, technical, infrastructure and go-to-market support designed to help them bring their ideas to market faster on the Arbitrum Platform. Here's what founders can expect during the 3-day program. If you're an early-stage team with a product, prototype, or clear business concept, apply today. Day 1: Sharpen the Product The strongest products start with a clear understanding of the problem they're solving and the users they're serving. On day one, founders will work with mentors to pressure-test the foundations of their business: Who is the user? What pain point are we solving? What is the onchain advantage? What's the smallest thing worth shipping? Through workshops, mentor and working sessions, teams will refine their product strategy, validate key assumptions, and identify the clearest path to launch on the Arbitrum Platform. Day 2: Go-to-Market Building a great product is only part of the equation. Founders also need a clear path to users. Teams will work through distribution, positioning, integrations, ecosystem alignment and user acquisition. The goal isn't a polished strategy deck. It's answering: Who do we target first? How do we reach them? What signal proves we're onto something? By the end of the day, teams will have a clearer plan for acquiring users, validating demand and building momentum after launch. Day 3: Demos, Prizes and Opportunities On the final day, teams will be able to submit their products for a chance to win up to $300K in prizes and grants. Winning teams will demo or pitch what they built, improved, or clarified during Founder House to the Arbitrum Foundation, Offchain, and industry-leading sponsors including Robinhood Chain and AWS, while receiving feedback from mentors, judges, and wider Arbitrum ecosystem. Winning teams will also receive an invitation to join Arbitrum's 8-week Mentorship Program for continued support as they scale their products and businesses in the programmable economy. Join us in London from July 10–12 and build alongside founders shaping the next generation of businesses in the programmable economy. Applications close June 25, 2026.
