## Job description

## About the Job

As a key growth accelerator, A11 partners with Europe’s most ambitious startups and scaleups, corporates and SMBs to connect them with top-tier talent ready to make an impact.

We're looking for a motivated Founder's Associate Intern (m/f/d) to join and drive projects across commercial and operations at one of our Ecosystem companies.

This is not a typical internship. You're part of the core team from day one. As Founder's Associate Intern, you'll work directly with the founding team on the operational and strategic development of the business, owning projects across sales, product, and strategy and turning ideas into action immediately.

Join the A11 Ecosystem - a next-generation procurement platform redefining how businesses discover, evaluate, and win public tenders across one of the world's largest yet most fragmented markets: €2 trillion in annual contract volume, scattered across 4,500+ portals in 29 countries. It harnesses qualified AI matching and agentic workflow automation to surface only the tenders that fit, analyze 100+ page documents in 30 seconds, and draft winning bids in minutes. Backed by leading investors, the company is scaling fast toward becoming the category-defining player in European public procurement.

In this role, you’ll:

- Identify and approach potential customers, and support demos and onboardings
- Plan, run, and evaluate sales and marketing campaigns
- Conduct research and validate hypotheses through customer interviews
- Build presentations and materials
- Support on documentation, research, and recruiting as needed

Your Profile:

- Structured work style with fast, independent execution
- High quality standards and attention to detail
- Relevant experience from consulting, startups, or VC
- Authentic, resilient, with high urgency
- Analytically sharp: you question assumptions and work with data, not gut feeling alone
- Passion for startups, growth, and entrepreneurship
- Strong communication skills in German and English

You might be a fit if you:

- Have solved messy, undefined problems before and enjoyed it
- Are curious about how startups actually work behind the scenes
- Can switch between strategic thinking and tactical execution without losing focus
- Care about delivering quality work, not just checking boxes
- Have something that shows you go all in, whether it's sports, a community, a project, or something nobody expects
- Are humble, coachable, and genuinely excited about doing hard things with good people
- See yourself founding or joining an early-stage company in the future

Please note that this position is based in Hamburg (on-site). This is a 6-month, full-time internship.

Benefits and Perks:

- Real ownership from day one. No support work; you drive projects independently
- Deep exposure to strategy, sales, product, and operations. You'll learn how B2B SaaS scales from zero to one
- Results over hours. What matters is what you move, not how long you sit
- Direct collaboration with the founders and an experienced founding team

If you’re eager to join the A11 Ecosystem and shape what’s next, we want to hear from you!
