Freshness (4 Sep 2026): Applications are open for Base Batches 004. Applications close 9 Sep 2026 (no clock time published on the page). Official page: https://www.base.org/batches

Base Batches is the official Base accelerator run by the Base Ecosystem Fund. Launched in 2025, the program runs twice a year. Batch 004 is the fourth cohort, for early-stage teams building the future of finance on Base.

This is an investment offer, not a grant. Selected teams receive an offer of $100K investment from the Base Ecosystem Fund. The official FAQ states Batch 004 is built around direct investment from the Base Ecosystem Fund rather than grants. Selected teams are offered that investment on a standard Simple Agreement for Future Equity (SAFE). Specific terms, including the valuation cap, are shared with teams at the offer stage and are subject to the fund’s diligence review. Accepting the investment is a condition of joining the program.

Verticals: trading, payments, agents, financing, and asset issuance.

What selected teams receive (from the page):

• Startup capital: $100K investment offer from the Base Ecosystem Fund
• Expert support: 8-week virtual program with a dedicated advisor, weekly support, and access to subject matter experts
• Amplification: content capture to help selected teams build visibility across the Base ecosystem
• Investor showcase: present to a curated room of VCs at Demo Day in New York in November 2026

Stage

• Pre-product to post-MVP
• Have not yet raised a formal Seed round

Base first

• Teams committed to Base as their default implementation and network of choice
• You do not need to be fully live on Base today, but the company should be focused on Base as its primary chain and default network of choice

What they look for

• Early-stage teams building products that can grow the onchain economy on Base, especially across trading, payments, agents, financing, and asset issuance
• Founders with clear insight and a credible path to building something meaningful

Applying does not guarantee funding. The official FAQ states that applying creates no obligation on Base, Coinbase, or the Base Ecosystem Fund to invest. All investments are subject to diligence, compliance review, and execution of definitive documents.
