Base Batches 004 accelerator

Base Batches 004 is the fourth cohort of the official Base accelerator, run by the Base Ecosystem Fund. The program started in 2025 and runs twice a year for a small group of early stage teams building on Base. This batch looks for companies in trading, payments, agents, financing and asset issuance that can grow the onchain economy on Base.

Selected teams receive an offer of a $100K investment from the Base Ecosystem Fund. They join an eight week virtual program with a dedicated advisor, weekly support and access to subject matter experts. Base also captures content to give the teams visibility in its ecosystem. The program ends with a Demo Day in New York in November 2026, where teams present to a curated room of investors.

The program is for teams from pre product to post MVP that have not yet raised a formal seed round. Base wants founders with clear insight and a credible path to building something meaningful. Teams should be committed to Base as their default network. They do not need to be live on Base today, but Base should be their primary chain.

Applications opened on August 19 and close on September 9, 2026. Acceptances go out on September 17. The virtual program runs from September 21 to November 15, and Demo Day is on November 17 in New York.

Apply through the form on the Base Batches page. Base says that applying does not guarantee funding and that the program is not a grant program.
