ABOUT KASTLE
Kastle is building the AI employee for banks. We work with some of America's largest financial institutions, helping them scale their contact center and compliance operations using autonomous AI Agents that process payments, originate loans, and help customers get a world class experience during the biggest financial decisions of their lives. We've processed over $2 billion in transactions and have raised a $24M Series A led by Insight Partners and Y Combinator. If you are interested in building AI that is applied in the real world where precision, reliability, and performance matter and redefine access to credit across the world, apply below.
ABOUT THE ROLE
We’re looking for a Founding Growth Lead to build the systems and campaigns that bring Kastle into new accounts and markets.
You’ll figure out who we should reach, what matters to them, and how to get in front of them. You’ll write the message, launch the campaign, build the tools behind it, measure the response, and use what you learn to improve the next one. You’ll also own the product story across our website, sales materials, newsletter, and events.
This is a hands-on role with wide ownership. The right person is an excellent writer and a fast operator who can build with data, automation, and AI tools. They have the taste to make Kastle memorable and the discipline to see whether their work creates real sales opportunities.
