First Growth Hire (Intern)

21st.dev (YC W26) is the Vercel for AI agents. Write your agent in TypeScript, deploy with one command, get sandboxing, streaming, chat UI, observability out of the box. 350K monthly active developers, 15K GitHub stars.

We ship fast and talk about it slow. Two founders, no marketing, no content person, no playbook. We need someone who can own our content and growth this summer. We need more of this, faster, across more channels: https://21st.dev/community/blog/build-agent-on-claude-code

You would make product videos, write technical use cases and tutorials, host hackathons with us in SF, and build partnerships with developers and companies in the ecosystem. You would live with us in SF. Room included, paid. You are in every conversation and every launch. That is how you learn the product well enough to represent it.

There is no playbook here. You would be writing it.

Already making stuff online? Write clearly? Interested in how technical products work? Good.

Summer 2026, 10-12 weeks, full-time path if it works.
