Founder’s Associate Intern (m/f/d) Venture Building

Das ist der Job

At ThirtyEight Capital, we don’t just invest in companies—we build them.

Darum lohnt es sich

As a Founder’s Associate Intern, you’ll spend your internship embedded in one of our portfolio companies, therapie1 , while working closely with the founders of both therapie1 and ThirtyEight Capital. therapie1 is redefining outpatient physiotherapy by combining outstanding therapists, modern technology and operational excellence to create a new standard of patient care.

Tasks • Work directly with the founder and leadership team on strategic and operational initiatives. • Drive cross‑functional projects with real business impact. • Analyze markets, competitors and customer insights to identify growth opportunities. • Support new clinic launches and expansion projects. • Improve internal processes and implement AI‑powered workflows. • Build financial models, presentations and business cases for key decisions. • Collaborate across operations, marketing, finance and business development. • Take ownership of projects from idea to execution.

Benefits • Work directly with experienced founders on high‑impact projects. • Gain first‑hand experience building and scaling a venture‑backed healthcare company. • Steep learning curve with real ownership from day one. • Exposure to venture building, operations, strategy and growth. • Flexible working environment. • Opportunity to join full‑time after a successful internship.

You’ll join at an exciting stage of growth and work on projects that have a direct impact on the business. This is not a typical internship. From day one, you’ll take ownership, solve real business challenges and gain first‑hand experience building a high‑growth company from the inside.

Requirements • Currently pursuing or recently completed a degree in Business, Economics, Engineering or a related field. • Strong analytical and problem‑solving skills. • Entrepreneurial mindset with a hands‑on attitude. • High level of ownership and willingness to take responsibility. • Excellent communication skills in German and English. • Comfortable working in a fast‑paced environment with changing priorities. • Experience with Excel, PowerPoint and AI tools such as ChatGPT is a plus. • Previous experience in startups, consulting, venture capital or private equity is a plus, but not required.

If you’re ambitious, curious and excited about building companies instead of just learning about them, we’d love to hear from you. Please send us your CV and a short note explaining why you’d like to join us. We care more about your curiosity, ownership and drive than a perfect résumé.
