Growth Intern (m/w/d) - Start-Up

• Pipeline. Build lead lists of medical and dental practices and run outreach by phone, email and LinkedIn, so our sales team always has qualified meetings.
• Growth engineering. Run our lead pipeline and automate it with AI and our CRM, so every recurring step only has to be built once.
• Onboarding. Bring new practices on board as smoothly as possible, from the switch away from their previous tax advisor and collecting documents and authorisations to integrating them into our tax processes.
• Client relationships. Be the personal point of contact for new practices in their first weeks. High-touch, responsive and proactive, so a good start turns into a long-term relationship and referrals.
• Experiments. Test new channels such as content, events and partnerships, with a clear hypothesis up front and an honest review afterwards.
• Funnel and pricing. Analyse conversion, onboarding times and pricing, and turn the numbers into concrete next steps for the founders.

Requirements

• First practical experience. You’ve done internships or working student roles in startup sales, business development or consulting.
• People person. You enjoy talking to clients on the phone and in person, and you build trust quickly.
• Structured & reliable. You keep many onboardings on track at once and nothing falls through the cracks.
• Analytical mindset. You read a funnel, spot where it leaks and know what to test next.
• AI-native. You use AI tools every day and build small automations yourself. CRM experience is a plus.
• German language skills. Our clients speak German, so we require fluent German (C2) and strong English (C1+).

Benefits

• Work directly with experienced founders. Learn first-hand from a team with backgrounds at Goldman Sachs, Harvard Business School, Bain & Company and Klarna, and from a former Y Combinator founder.
• Build the growth engine. Shape how an AI-native tax firm wins and onboards clients, at an early stage and with direct impact on revenue.
• Close to clients. Talk to practice owners every day and learn how medical and dental practices work financially.
• Ownership from day one. Take on real responsibility early, on live clients, deals and projects.
• Front-row seat to AI in the real world. See how AI transforms a traditional industry and help build it.
• Steep learning curve. Work on real problems, ship quickly and build skills that prepare you to start your own company.
• A path to stay. Strong interns get an offer to continue as working student or full-time.

The details

Full-time internship for 3 to 6 months, start any time of the year, on-site in our Berlin office five days a week.
