Help us build the AI workforce for thousands of businesses.
Castyl is a fast-moving AI services agency. We hire interns who want real ownership — not coffee runs. You'll ship work that books real revenue for real clients, from day one.
We're small, profitable, and growing fast — which means interns do real work, learn the cutting edge of AI, and see the impact immediately.
Real ownership
You'll own outcomes, not tasks — your work goes live for paying clients in days, not someday.
Learn AI + sales
Get hands-on with the AI tools and sales systems companies are paying thousands to adopt.
Direct mentorship
Work shoulder-to-shoulder with the founders. Weekly 1:1s, fast feedback, no layers.
Move fast
Ship daily, measure everything, and watch the numbers move. No bureaucracy, no busywork.
Remote-friendly
Work from anywhere. We care about output and ideas, not where you sit.
