Founding Growth Marketer

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 an experienced Founding Growth Marketer (m/f/d) to join and build the growth and paid-acquisition engine at one of our Ecosystem companies.

As a Founding Growth Marketer, you'll be the first dedicated marketing hire and own growth and paid acquisition end to end, from the first impression to the booked demo. We already punch well above our weight on SEO and GEO, with strong scores and a proven strategy; your job is to make that even better and to build the acquisition and experimentation engine around it that turns visibility into a predictable, measurable pipeline. This is not a strategy or "manage the agency" seat, and there's no team to delegate to yet. You're hands-on in the ad accounts, the analytics, the landing pages, and the creative.

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:

• Push our SEO and GEO further. We already rank and get cited; your job is to extend that lead and stay ahead as AI search evolves
• Own paid acquisition across Google, LinkedIn, and Meta, from setting up campaigns and targeting to budget allocation and daily optimization
• Run a continuous loop of growth experiments: form a hypothesis, ship it, read the data, and either double down or kill it
• A/B test landing pages relentlessly and hunt for the messaging that actually converts
• Own the creative pipeline: brief and organize photo/video shoots, produce the assets your campaigns need, and keep the brand sharp
• Own marketing analytics and reporting end to end: attribution, CAC, pipeline contribution, and the dashboards that tell us what's working and where the next euro should go
• Feed every signal back to the founding team: what messaging lands, which channels and verticals respond, and where to lean in

Your Profile: 

• Hands-on experience running paid B2B campaigns across Google, LinkedIn, and/or Meta, with real budget and accountability for results, ideally in B2B SaaS
• A real growth-experimentation mindset: you've run structured tests, not just one-off campaigns
• You live in the numbers: you can build the attribution model and read it, not just admire someone else's dashboard
• A strong understanding of SEO and GEO, and the instinct to keep improving an already strong position
• Full-funnel instinct: you think about the landing page, the messaging, and the demo, not just the click
• Comfortable directing creative: you can brief a shoot and judge what makes a good ad
• Comfortable building automated, AI-first workflows with tools like Claude Code, n8n, and similar
• Clear, confident communication in German, plus strong English

You might be a fit if you:

• Are the kind of person who figures things out before asking for help
• Get a kick out of watching a CAC curve bend the right way because of something you shipped
• Want to build a marketing engine from scratch, not inherit someone else's dashboard
• Are hungry for ownership and not interested in waiting for permission
• Care about results but stay humble about what you don't know yet
• Have something outside of work that shows you don't do things halfway, whether that's competitive sports, a side project, or something completely different
• See this as the launchpad for a career as a growth leader or building your own thing

Please note that this position is based in Hamburg.

Benefits and Perks:

• The founding marketing role with real ownership over budget, channels, and the marketing growth playbook
• Shape the GTM and product story alongside the founders
• Performance-based compensation on top of base salary and equity
• An AI-native marketing stack; you'll work with the best tools from day one
• A front-row seat to building a company in a massive, untouched market

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