​Arbitrum Founder House Singapore 🇸🇬

​In collaboration with Robinhood Chain

​Open House brings together founders and teams building the next generation of onchain businesses. Following editions in New York City and London, which engaged 2,160 builders across online and in-person activations and received 177 and 273 project submissions respectively, Open House is coming to Singapore.

​The program began with a global online Buildathon from September 14 to October 4, followed by Founder House Singapore, an application-only, three-day experience for founders with an existing product, prototype, or business. Founder House gives selected teams focused time to build, test their direction, and connect with the Arbitrum ecosystem.

Note: This form is for Founder House applications only.

​📅 Online Buildathon: September 14–October 4, 2026

​About Founder House

​Founder House Singapore is part of Arbitrum Open House, in collaboration with Robinhood Chain. It is designed for founders who are already building and are ready to make meaningful progress on their product.

​Over three days, selected teams will build alongside other founders, receive feedback from mentors and ecosystem participants, and work through product, technical, and go-to-market challenges.

​Come with an existing project. Use Founder House to build or launch a meaningful new feature, validate a key assumption, and leave with a clearer path forward.

​Prizes and Grants

​Founder House participants will have access to $300K in prizes and grants across several opportunities:

• ​General Builder Track: $120K in prizes for three standout teams building innovative products on Arbitrum and Robinhood Chain

• ​Robinhood Chain Founder-in-Residence Award: A $60K award for an eligible team building on Robinhood Chain

• ​Robinhood Chain Innovation Award: A $30K award for eligible innovation on Robinhood Chain

• ​Promising Products Track: For emerging products exploring areas such as AI agents and new financial primitives

• ​Ecosystem Grants: For teams with strong potential and ecosystem alignment

​Most prize tracks include milestone-based funding to support continued execution after Founder House. The Promising Products Track is evaluated separately. Eligibility varies by track; the full Founder House prize pool is not limited to Robinhood Chain projects.

​Who Should Apply

​We’re looking for solo founders and teams with an existing product, prototype, or business that can meaningfully use Arbitrum. Areas of interest include:
