Founders Associate Intern

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

Future founders: learn how to transform an industry using AI. You work directly with our founders on the topics that matter most right now, from investor updates and product to growth and finance, and you own each workstream from question to result.

Tasks

• Investor relations. Prepare investor updates and board materials, from KPIs and financials to the storyline.

• Reporting, controlling and finance. Build and maintain the reporting and financial planning that keeps Taxforce running, and support our invoicing, cashflow management and the monthly internal close.

• Product. Shape our business intelligence product for practices, from monthly business analyses (BWA) to the reports that show practice owners where they stand on revenue, costs and liquidity.

• Growth. Build and test ways to win new practices, from lead lists and outreach to content, partnerships and pricing.

• Onboarding and support. Maintain our client onboarding process and help run client support, so that happy practices drive organic growth.

• Getting things done. Own topics that cut across teams or have no owner yet, fix manual workflows at the root and automate them with AI as you go.

What this role is not: an assistant role, or strategy that stays on slides.

Requirements

• Drive & ambition. You go the extra mile and thrive in fast-paced startup environments.

• First practical experience. You’ve done internships or working student roles, ideally in consulting, investment banking, VC or tech.

• Strong academic background. You study at or graduated from a well-regarded university or business school.

• Analytical mindset. You break down complex problems and prioritise between many tasks.

• Tech-savvy. You use AI tools every day and build small automations yourself.

• German language skills. Our clients mostly 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.

• Learn from founders who have done it before. Work alongside a former Y Combinator founder and see first-hand how a company is built from zero.

• 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.

• Hands-on venture building. Broad scope across growth, finance, operations and technology instead of one narrow function.

• Steep learning curve. Work on real problems, ship quickly and build skills that prepare you to start your own company.

• Future founders. Build the skills and the network to start your own company in a few years.

• 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.
