Chief of Staff Intern (fmd) AI Startup Serial Entrepreneurs

We are building Germanys 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.

Were building the alternative.

Founded in 2025 Taxforce rethinks tax advisory from the ground up: AI-powered and highly automated yet personal. Were starting with healthcare professionals a complex and underserved segment with the ambition to expand into many more industries over time.

Instead of pure compliance we deliver real advisory and become long-term partners to our clients: from initial setup to established organizations.

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. Were writing them.

Youll work directly with the founders take on real responsibility from day one and see how AI transforms a real-world industry.
