Ethereum Builders After Hours: Presented by the Ethereum Foundation
Ethereum Builders After Hours
Hosted by: Ethereum Foundation • Arbitrum Foundation • Virtuals • Frachtis
An evening to meet the right people who will actually move the needle.
A semi-structured networking event hosted by those operating at the frontier of Ethereum. Come for conversations that lead somewhere — not just handshakes.
What makes this event special
Not a party — a curated setting.
No distractions. A minimal format: Intros, good food, a great location and open conversation.
Intentional connections.
Attendees are pre-vetted for quality and intent. You’ll meet founders, investors, and ecosystem builders who are genuinely interested in meaningful exchange.
Structure to help you connect.
We’ll have a simple framework in place to make it easier to find the right people and start the right conversations. The registration process also helps us understand who you’d like to meet, so we can facilitate useful introductions on the ground.
The hosts
Ethereum Foundation — the core institution and non-profit behind the Ethereum ecosystem. Their work underpins many of the protocols, standards, and developer communities active today.
Arbitrum Foundation — Arbitrum combines low fees, fast finality, and strong security with a thriving developer community. Builders can launch on Arbitrum One or deploy their own customizable chain using the Arbitrum stack — fully EVM-compatible, supporting Solidity and Rust, and connected to deep Ethereum liquidity.
Virtuals — a newer frontier combining on-chain identity, AI agents, and creative tooling. They represent the next wave of social and builder experiences in agentic commerce.
Frachtis — a crypto-native pre-seed fund backing infrastructure, AI, middleware, and consumer apps. Early-stage, conviction-driven, and aligned with long-term founder support.
