The posting

Here's what this role looks like in practice: setting up banking and financial operations across three countries, supporting fundraising efforts, modeling the strategic options for a new business line, running candidate trial days, building internal AI agents, organizing events with top-tier partners, and contributing to GTM. Not hypotheticals — all of this has actually happened in this seat.

The range is the job. One hour you're framing a business-model decision for the founders; the next you're chasing a teammate for a missing receipt so the month closes. If either end of that spectrum feels beneath you or beyond you, this isn't the role. The topics change every day, and you have to like that.

This is not a coordination role, and not a note-taking role. You work directly with the three co-founders, you're in the room for every critical decision, and you own the execution that follows.

WHAT YOU'LL DO

We'll iterate from here, but this is the real, current scope:

- Frame strategy before it becomes a project. You're the first one on new strategic topics - a business model option, how to approach a new market, a build-vs-partner call. You structure the question, run the first pass of analysis, and give the founders a direction to react to before anyone commits resources.

- Run financial operations. Three entities (US, Germany, Spain), external accountants in each, banking across four providers, payroll, invoicing, spend and receipt tracking, month-end coordination. You own the numbers being right and you automate as much of it as possible.

- Participate to recruiting operations. Source, screen, and coordinate candidates across business roles. Prepare and run our structured trial days, and help close top talent.

- Build with AI agents, not just spreadsheets. We run internal agents for most of what we do, built by the business team using coding agents like Claude Code or Codex. You'll extend this fleet. If a task is done manually twice, you build the thing that does it a third time.

- Support the GTM engine. Target account research, outbound infrastructure, CRM hygiene, event operations... from CFO dinners and conference sponsorships to hackathons we co-organize with top-tier partners.

- Be founder leverage. The weekly all-hands deck, investor updates, briefing materials, speaker submissions, meeting follow-ups. You make sure founder time goes to the highest-value activities and nothing falls through the cracks - including the unglamorous parts. Legal coordination, vendor management, office logistics: if it has no owner, you're the owner.

- Prepare for what's next. As we grow, new topics will land on our desk quickly. You'll own them.

WHAT WE'RE LOOKING FOR

- 3–4 years in a high-intensity environment. Top-tier consulting, banking, VC/PE, or an early-stage startup. You've been the person things get thrown at.

- Genuinely AI-native. This is a hard requirement, not a buzzword. You already use AI agents to do real work. You've automated a workflow, built something with a coding agent, or run your job through tools most people haven't heard of yet. We'll ask you to show us.

- The full spectrum, gladly. You take a strategic framing session and a receipt-chasing task in the same afternoon with the same energy. You can context-switch without losing the thread. No task is beneath you; no topic is above you.

- Extreme ownership. You see gaps, you fill them, and you don't wait to be told. When something has no owner, you're the owner.

- Analytical range. You can build a financial model, structure a market analysis, and write a compelling narrative with equal comfort.

- Writing that doesn't need editing. Investor updates, candidate emails, partnership briefs - clear, direct, done.

- Technical curiosity. You don't need to write code, but you understand how software gets built and can engage credibly with engineers - and direct AI agents that build for you.

- Fluent English. It's our working language.

This is a wishlist, not a checklist. If the role excites you but you don't tick every box, we would encourage you to apply anyway.

NICE TO HAVE

- Experience in fintech, B2B SaaS, or the office-of-the-CFO space

- Prior startup experience (founding, early employee, or operator role)

- Exposure to fundraising processes. You've seen how rounds come together

- Spanish or German

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
