Why cohort-based?
It's a fixed commitment of only a few meetings. The first cohort begins in September 2026 and runs until November. We plan to run more cohorts and open the community up to more people next year.

FAQs
What is Growth Circuit?
Every month, the group builds around one theme, tool, problem, or question. You explore it in your own time, then come together to share what you made, what broke, and what you learned.
What is a Marketing Engineer?
A marketing engineer is a marketer who got tired of waiting for someone else to build the thing they need. It is an emerging role that combines taste and curiosity with technical ability: writing scripts, connecting APIs, spinning up agents, and transforming manual processes into systems that scale.
What about people outside New York?
We want Growth Circuit to reach other cities and be accessible online too. The first cohort starts in New York. Join the global waitlist and we will reach out when there is something for you.
