Why this role is remarkable

- Directly partner with a world-class founding team, including the co-founders of Taulia (financial supply chain leader) and Finoa (crypto custody platform).
- Join a $10M seed-stage venture led by Creandum, operating at the bleeding edge of agentic AI and B2B fintech infrastructure.
- Gain unparalleled exposure to every facet of company building, from board-level strategic framing to hands-on international financial operations and GTM execution.

What You Will Do

- Frame and analyze strategic decisions, such as new market entries and build-vs-partner calls, before the founders commit engineering resources.
- Own financial operations across the US, Germany, and Spain, managing banking, payroll, and automating workflows with AI agents like Claude Code.
- Drive founder leverage by managing investor updates, coordinating recruitment trials, and leading GTM initiatives like partner hackathons and account research.

The idóneo candidate
