Cartesia x Anthropic Voice Agents Hackathon hosted by Notion

Calling all engineers, startup teams, and product-minded operators. Join Cartesia, Anthropic, and Notion for a two-day, in-person hackathon at Notion HQ in San Francisco. This event is designed for startup founders, early teams, and EPD leaders who want a real technical challenge and space to go deep, alongside other ambitious builders.

You’ll build voice-first AI agents that combine real-time audio with reasoning, memory, and action, projects meant to persist beyond a demo. Standout teams will receive generous product credits, potential access to early features or special enablement, and editorial and social amplification from our partners, including BrowserBase, Exa and Coval. The real upside is shipping something credible — and getting it seen.

Top founders, operators, and technical leaders across AI, voice, and developer tooling to serve as speakers and judges— announcements coming soon.

Note: This event is fully in person in San Francisco. Teams of up to four, with each member required to apply individually. Applications are reviewed on a rolling basis and space is limited.
