GTM / Growth
Sales & Business Development
Munich, Germany
Posted on Jul 31, 2026
You build the go-to-market engine: the channels, systems and data that turn pilots into a scalable sales motion in a traditional, hard-to-reach market. You work hands-on with a real product and pilot customers, and help build an AI startup from the inside.
What you’ll do
- Own GTM channel strategy and experiments: guilds, chambers, trade fairs, manufacturer and wholesale partners.
- Set up CRM and outbound (for example HubSpot), the funnel and tracking.
- Run data-driven growth experiments and ICP prioritisation.
- Competitive analysis and positioning.
What you bring
- Studies in business, business informatics, industrial engineering or similar (TUM School of Management), or as an unpaid internship.
- Analytical and systems-minded, and you have built or run something scrappy before.
- Hands-on with tools and data. You use AI tools (Claude, ChatGPT, Gemini or similar) as part of your daily workflow.
- German fluent (must), English a plus.
Why KalkulAI
- Radical ownership from day one. No fixed job description, you own outcomes.
- A live product with real pilot customers, not a lab hypothesis.
- You never start from zero: you build on real, existing progress.
- AI-native: Claude, Codex, GPT and Gemini are part of how we work every day.
- You sit side by side with the founding team.
- Honest deal: this is unpaid, but you gain real ownership and startup experience most roles never offer.
- Backed by EXIST, TU Munich and UnternehmerTUM.
