Company Description

Causa Prima is a $10M Creandum-backed AI fintech startup founded by serial entrepreneurs from Taulia and Finoa, building agent-to-agent networks to automate B2B finance operations.

You will work directly with three serial co-founders to scale an AI-native fintech. This high-intensity role spans framing strategic business models, managing international financial operations across the US and Europe, and building automated internal workflows using AI agents. You'll own critical execution from GTM support to fundraising, acting as the primary lever for the founding team.

Location

Madrid, Spain

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
- Brings 3–4 years of experience in high-intensity environments like top-tier consulting, investment banking, VC/PE, or an early-stage startup.
- Is genuinely AI-native, with proven experience using coding agents or automation tools to solve complex operational problems in their daily work.
- Demonstrates extreme ownership and the ability to switch between high-level strategic modeling and unglamorous administrative tasks with equal energy.
