What You Will Actually Do

We’re looking for an experienced, full-time Executive Assistant to join our team in Berlin and support our Co-CEOs, Lennard and Judith.

In this role, you’ll work closely with our Co-CEOs, Lennard and Judith, as part of a young, entrepreneurial team. If you thrive in fast-paced environments, love bringing order to hectic schedules, and approach each day with a proactive mindset, we’d love to meet you.

We’re looking for someone highly organized, calm, self-motivated, and adaptable.

Internal organisation and steering. You run the CEO's operating rhythm. Calendar, inbox triage, meeting preparation, and follow-through all sit with you. You keep an eye on details and you keep the leadership cadence (weeklies, board preparation, offsites) moving.

External travel and speaking. You plan and book complex international travel end to end, and you manage the speaking pipeline: inbound requests, selection, briefing packs, and logistics on the ground.

C-level relationship management. You become the trusted point of contact for the CEO's most important external relationships: customers, partners, and investors. You track who needs a touchpoint and when, and protect these relationships through reliability and proactivity.

Augmentation and anticipation. You work half a step ahead of everyone else in the room. You can identify a bottleneck before it forms. You build the systems, defaults and briefings that let the CEO spend their time on judgement rather than logistics.

Admin. You manage expenses and finance admin and can support with occasional personal assistant (PA) duties as needed.

CEO office collaboration. You’ll work in very close coordination with the CEO office, which includes a Chief of Staff and CEO Office Manager who are responsible for operational processes in the CEO office. Incl. performance management, KPI tracking, leadership accountability and strategic projects).

You Might Be a Fit If…

You have previously supported a CEO or equivalent in a demanding organisation and are looking for another environment that gives you an opportunity to grow.

You want to be in a young, fast company. You are comfortable with ambiguity, short timelines and a team that is still writing its own playbook, and you would rather shape the system than inherit a finished one.

You are mission-driven. You care that European companies build and adopt AI, and you want your work to count toward that rather than toward a job title. You are eager to automate your own work where possible.

AI can do a lot of things, but in the short term, it won't be able to shepherd a growing group of mostly young people in a very dynamic environment. We are looking for someone who can foster the most important human qualities within the organization.

We are looking for a long-term partner, not someone optimizing for their next role.

Personified calmness – You bring order, not chaos. When things get hectic, you're the person who slows down, thinks clearly, and helps others do the same. Your presence makes people feel like things are under control. You instill calmness and continuity in the organization.

Good judgment – You know what matters and what doesn't. You read people well. You understand when to push and when to give space, when something is urgent and when it can wait.

Compassionate and empathetic – You care about the people around you. You understand that behind every missed deadline or dropped ball is a human with hidden context. You hold people accountable with kindness.

Ownership mentality – You see problems and fix them without being asked. You don't wait for permission. You follow through.

Strong communicator – Written and verbal. You can draft important emails or have a difficult conversation with equal skill.

Trustworthy – You'll have access to everything and work directly with the CEO. Discretion and trust are very important.

The Environment

We work from our office in Berlin, Greifswalder Strasse 212. Everyone works together in person because the hardest problems get solved faster at a whiteboard than in a Slack thread. Conversations happen faster, problems get solved quicker, and we actually know each other.

Days start at 8:30. Lunch & dinner are together. We run, go to the gym, and take care of ourselves. Health is not separate from work here, it is part of how we work well.

The vibe is calm but intense. No one is yelling or panicking. But everyone is working hard on things that matter.

Compensation

Salaries are transparent and tied to levels, not negotiation. All roles include equity.

We will figure out the right level together based on your experience and scope. Levels are about the work you own, not your title or years of experience. We narrow down the expected salary range early in the process.

Next steps

We move fast. Most processes complete within two weeks.

If this sounds like your kind of work, we would like to meet you.
