Tokyo

To meet demand, a second event just for independent developers and early-stage founders: founder stories, builder deep-dives, and laptops-open workshops from our Applied AI team. Code with Claude is where you hear what's new. Extended is where you see it in the wild.

In-person applications are now closed. Applicants will be notified of their status in early April.

Attend virtually

Founder stage

When anyone can build, the founder's edge is knowing what to build and sticking with it. Sit in with founders and technical leaders from startups built on Claude as they walk through the bets they made, the road from prototype to first revenue, and the judgement calls they’ve made.

Builder stage

You don't need a CS degree or an engineering team to ship real software anymore. You need a problem you understand and the will to solve it. We’ll see working demos, real code, the techniques behind each.

Workshops

Join the same hands-on sessions Anthropic uses to train its own technical staff, adapted for you. Ship your first managed agent, give it memory, write evals that move the score, compose multi-agent systems, then put it all to the test in a live agent battle.

Agenda

Demos and office hours run all day. Drop by for a demo between sessions. Sign up in advance for office hours. All times in Japan Standard Time (JST).
A note on language. Sessions run primarily in English with some in Japanese (marked on the agenda), and live simultaneous interpretation is available in both directions throughout the event. Office hours are held in English.

FAQ

Demand to attend Code with Claude in-person far exceeded our expectations. To be able to give more people access to the event experience, we added a second day just for independent developers and early-stage founders.

Code with Claude is designed for software developers, engineers, and technical leaders who are building with AI. Whether you're just getting started with Claude or are an experienced builder, you'll find sessions tailored to your level.

Space is limited. Given the demand for in-person attendance at Code with Claude, invites to Code with Claude: Extended were made to existing applicants.

Code with Claude: Extended will not be livestreamed. Sessions will be recorded and made publicly available after the event.

No, in-person attendance is free.
