Kastle is building AI employees for banks, helping major financial institutions scale contact center and compliance operations using autonomous AI agents. The company has processed over $2 billion in transactions and raised a $24M Series A led by Insight Partners and Y Combinator.
As Founding Growth Lead, you will own the systems and campaigns that bring Kastle into new accounts and markets. This is a hands-on role with wide ownership spanning market strategy, outbound execution, messaging, and events.
Key responsibilities:
- Build and maintain a live market map identifying target accounts, buyers, and relationships across current segments and new verticals
- Create paths into important accounts by leveraging investor networks, preparing thoughtful outreach, and converting warm introductions into conversations
- Own outbound and marketing experiments: build lists, develop hypotheses by audience, write copy, launch campaigns, and iterate based on reply rates, meetings, and pipeline data
- Build growth tooling including AI agents, automations, dashboards, and workflows to maintain the market map, run campaigns, track leads, and provide sales visibility
- Own Kastle's product messaging across website, sales materials, newsletter, and events—translating customer conversations and product capabilities into clear positioning
- Plan and execute conference presence, smaller events, and industry-specific campaigns with full ownership of audience, invitations, experience, sales prep, and follow-up
- Test creative outreach approaches such as thoughtful gifting, podcasts, customer programs, and Kastle-hosted events
A sample project: build a living market map that auto-updates daily, connecting target accounts and buyers to existing relationships, outreach, meetings, customers, and events, then use it to prioritize accounts and messaging.
You are creative with strong taste, resourceful, fast yet thorough, technical and curious about data and AI tools, analytical about campaign results, highly independent, and high-energy. Background in growth, product marketing, GTM engineering, founder's office, or building something yourself is valued; the company cares most about what you've personally created and the results it produced.
REQUIREMENTS:
No specific years of experience, education, or certifications stated. The posting emphasizes demonstrated capability: ability to develop sharp messaging and unusual campaigns, resourcefulness, speed with attention to detail, comfort with data and AI tools, analytical rigor, independence, and high energy. Applicants should provide examples of campaigns, events, or internal tools built, with clear ownership and measurable results.
