Forum X Anthropic Hackathon: Agentic AI for Zero-to-One Company Building
Build the next generation of agentic AI — agents that make starting a company faster, smarter, and more accessible.
Anyone can start a company. Not everyone knows how to get from zero to one. In one day, you’ll build autonomous, context-aware agents that automate the toughest early stage workflows: customer discovery, validation, prototyping, testing, GTM, and sales.
What you'll build
Participants will create agents that compress months of work into hours:
Customer Discovery – Identify and segment the right early customers.
Validation – Run research, surface pain points, and score solution fit.
Prototyping & Testing – Integrate with tools, generate code, or trigger workflows.
Go-to-Market & Sales – Source leads, personalize outreach, and close deals faster.
Builders will have access to Claude Code, Anthropic’s AI-powered coding environment designed for fast iteration and problem-solving — ideal for creating, testing, and refining agents in real time during the hackathon.
What you’ll walk away with
A live demo you can keep building, pitch, or sell.
Feedback from experienced zero-to-one founders.
Exposure to mentors and investors who can help you take the next step.
Who should apply
The hackathon is a rare collision of:
Technical builders exploring the founder path.
AI-native hackers with speed and scrappiness.
PhDs and researchers ready to test outside of the lab.
You’re not just competing, you’re building alongside the same people shaping the next generation of AI-native companies.
Learn from the best
Learn directly from GTM leads at Anthropic, AI/ML engineers from Intercom and ScaleStack, and the Forum Ventures Venture Studio team building AI companies from zero to one.
