Founders Associate Intern (m/w/d) - Startup

We are building Germany's leading Tax Advisory firm. Taxforce was founded based on a simple observation: Many business owners want a tax advisor who acts as a true sparring partner: proactive, responsive, and strategic. What they often get instead is a service provider: booking receipts and filing tax returns, with little real advisory.

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 we're building Taxforce specifically for, growing both organically and through M&A, with the ambition to expand into many more industries over time.

This is a €40B market in Germany alone, with processes that have barely changed in decades. AI is now enabling 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 and the former Klarna Head of Engineering. You’ll work directly with the founders, take on real responsibility from day one, and see how AI transforms a real-world industry.

We offer a high-ownership environment, direct feedback and mentoring, a collaborative team, and competitive salary all from our office near Boxhagener Platz.

Join early and help us redefine tax advisory.
