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

We are building Germany's leading tax advisory firm. Many business owners want a tax advisor who acts as a true sparring partner: proactive, responsive and strategic. What they often get is a service provider that books receipts and files returns, with little real advice. We're building the alternative.

Founded in 2025, Taxforce rethinks tax advisory from the ground up: AI-powered and highly automated, yet personal. We're starting with healthcare professionals, a complex and underserved segment, and we grow both organically and through M&A.

This is a €40B market in Germany alone, with processes that have barely changed in decades. AI now enables a fundamental shift, and there are no playbooks yet. We're writing them. We're a small, highly ambitious team in Berlin, backed by €5M from Tenet VC and founded by alumni of Goldman Sachs, Harvard Business School, Bain & Company, Y Combinator and the former Klarna Head of Engineering.

The role

You help doctors’ and dentists’ practices find their way to Taxforce and make sure their start with us feels effortless. You work directly with our founders, run our pipeline from first contact to signed mandate, and own the onboarding of new practices until they are fully part of our tax processes.

Tasks

• 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.
