Founder's Associate Intern (f/m/x) - starting Jan. '27

Become part of Tanso and decarbonize industries with us.

What if the impact of your role extended beyond a job title?

Not through marketing spin. Not through vague "purpose-driven" messaging. But through software that helps industrial companies understand, manage and actively reduce their environmental impact.

That's what Tanso is building. And it's one of the reasons people join us.

Why Tanso?

• Take Action in a Fast-Moving, High-Impact Environment. We move fast on sustainability because the urgency is real. That means decisions that matter, transparent processes, and the agility to navigate change.
• Challenge & Grow Through Ownership. Take ownership immediately, build expertise through hands-on experience, and leverage every available resource to achieve outsized impact.
• Foster Trust with Mission-Driven Collaborators. You'll join a team that prioritises impact and each other. We give honest feedback, share credit, support each other when it matters, and hold high standards together.
• Embrace Responsibility & Drive Impact. Turn fragmented emissions data into actionable insights. Your work has immediate, visible impact - clearer decision-making and genuine momentum toward change.
• AI First-Mindset. We embrace cutting-edge technology to solve sustainability challenges. Push the boundaries of innovation and stay ahead of what's possible.
• Commitment to Performance & Excellence. We cultivate a high-performance culture where you thrive. Push yourself and others to excel, celebrate wins, learn from setbacks, and raise the bar.

Your role

To support during a period of four to six months, working on several topics; a new module going to market, a business case that decides whether we enter a new segment or an internal process that needs to be rebuilt before it breaks, we are looking for a Founder's Associate Intern (f/m/x).

As Founder's Associate Intern, you'll join the small team that works directly with our CEO and management on Tanso's highest-priority initiatives – the ones that are too new, too urgent or too cross-functional to sit neatly in one department.

You'll get real responsibility early, honest feedback constantly, and a front-row seat to how a B2B software company actually gets built.

In exchange, we expect you to push. This is a demanding role in a demanding team, and the people who thrive here are the ones who treat the time as a chance to compress a year’s learning into a few months.

Key responsibilities

• Own workstreams within our most important projects – research, analysis, coordination and delivery – with direct exposure to our C-level and management team.
• Support the go-to-market of new modules: build demo data, prepare prospect materials, join customer calls, and turn what you hear into a product that sells.
• Dig into new EU sustainability regulations and translate dense legal text into something our product, sales and marketing teams can actually use.
• Build the artifacts decisions get made on: business cases, market analyses, management presentations, and internal documentation.
• Clean up the data. Chase the missing input. Take the notes and turn them into decisions. Format the deck. Fix the thing nobody else has time to fix.

Your profile

• You're studying towards or have recently completed a Bachelor's or Master's degree with strong results, with previous internship experience in a startup, consulting, VC or a similarly demanding environment.
• You think and act like a founder: proactive, comfortable with ambiguity, and you take ownership without being asked twice.
• You're highly structured and analytical – you can break a vague question into a plan and come back with an answer, not a list of open points.
• You're comfortable with technology and AI tools, and you're curious to try building things yourself.
• You have a practical interest in sustainability and sustainable regulations that lets you hold your own in product and customer discussions.
• You have exceptional written and verbal communication skills in both German and English.
• You get excited by the idea of growing a startup into a successful scale up.

This is a four to six month internship, starting Jan. '27 (earlier start possible).

What we offer

• Hybrid working model that combines the benefits of onsite collaboration with the flexibility needed.
• Sponsored access to EGYM Wellpass to prioritize your wellbeing with thousands of options.
• Exclusive discounts that help you save on a wide range of everyday brands, services, and experiences.

Our team

We're a diverse group of people, and that diversity is what makes us great. We bring unique perspectives to everything we do and are always eager to learn from each other. We work in cross-functional teams to tackle ambitious challenges, actively seek feedback and be the best versions of ourselves.
