Founder's Associate - Marketing (m/f/d)

Around 74% of all CO₂ emissions in Germany are related to energy production, which is over 543 million tons per year.

To achieve the European climate goals, we must address this problem urgently and decisively, and this is precisely where we at Sunpeak Capital come in.

We make the expansion of renewable energies investable and transform photovoltaics, battery storage, and charging infrastructure into high-yield, tax-optimized investments. Our approach combines climate protection with financial intelligence: a true win-win for the environment and investors.

With our combination of specialized consulting processes, innovative investment structures, and a broad network of project developers, we enable private and corporate investors to actively shape the energy transition, profitably and sustainably.

We are consistently scaling our model within Germany, where the energy transition is decided. Become part of our team and contribute to capital flows being directed where they generate the greatest climate benefit and real returns.

Responsibilities

Your Role

You will build our marketing from scratch together with the founders. Much does not yet exist, some is already running: You will bring new channels and processes from 0 to 1 and scale existing ones from 1 to 10. Content, newsletters, and performance marketing will be your responsibility, from strategy to execution. You will decide what is prioritized, be responsible for the results, and also appear in front of the camera yourself. We are not looking for someone who just processes briefings, but for someone who 100% owns the growth topic at Sunpeak Capital.

• Marketing and Growth Strategy: You will develop the growth strategy with the founders, define target groups, channels, budgets, and KPIs, and be responsible for end-to-end implementation.
• Content Marketing from 0 to 1 and from 1 to 10: You will conceptualize and produce YouTube videos, podcasts, LinkedIn, and Instagram formats, appear in front of the camera yourself, and shoot with our founders. This includes editing, post-production, thumbnails, and adapting longform content into Reels and Shorts.
• Newsletter Marketing: Our email marketing is already running. You will further develop it: continuously optimize segmentation, automations, content, and lead nurturing along the entire investor journey for open rates, engagement, and conversion.
• Performance Marketing: You will take over our paid campaigns (Meta, Google, LinkedIn, YouTube) and engage heavily in testing: new campaigns, creatives, target groups, and landing pages. You will rebuild remarketing. Everything is tracking, data, and KPI driven; you will regularly analyze performance and consistently optimize for lead quality and acquisition costs.
• Brand: You will further develop how Sunpeak sounds and looks, and consistently apply the brand across all touchpoints, from social media to investor materials to internal presentations.
• Funnel and You will connect marketing and sales, work closely with our CRM (HubSpot), and make it visible which measures actually bring in investors.
• AI-First: You will build our marketing AI-first and leverage AI tools to increase efficiency in all areas: content creation, editing, creatives, campaign analysis, and process automation. What doesn't need to be manual, won't be manual with you. We provide the budget for the appropriate tools; you decide which ones they are.
• Perspective: With growing success, you will build your own team and lead interns, working students, and freelancers.

Qualifications

• You have 2 to 3 years of work experience in a growth or marketing role at a startup or scale-up and a proven track record: channels, campaigns, or processes that you have measurably built or scaled.
• You are hands-on in at least two of the three areas: content, newsletters, and performance marketing, and are eager to master the third.
• You quickly delve deep into renewable energies, photovoltaics, battery storage, and the tax logic of our investments. Only those who understand the product can do marketing for it that convinces investors.
• You work data-driven: tracking, attribution, A/B tests, and reporting are tools for you, not buzzwords. You have a good eye for aesthetics and storytelling, and experience in video editing, ideally also with cameras, sound, and lighting.
• You enjoy being in front of the camera yourself or are willing to learn. You understand how YouTube, LinkedIn, and Instagram work, in both short and longform content. You work AI-first: AI tools are an integral part of your workflow in content production, analysis, and automation, and you actively seek further leverage to become faster and better.
• You work with high autonomy, make decisions independently, and take responsibility for results, even when it gets uncomfortable. Very good German language skills and a keen sense for language and tone.
• You are available for a full-time position and willing to work 5 days a week in our Berlin office. Bonus: You already have prior knowledge of renewable energies or energy markets, or have experience in marketing for financial or investment products.

Benefits

• Ownership and Impact: You will help build Sunpeak Capital's marketing from the ground up, work directly with the founders, and have a formative influence on how we are perceived in the market.
• Competitive Compensation: Top performance is adequately compensated with us.
• Free Urban Sports Club Membership: Work out after work.
• Modern Office in Berlin Mitte: Barista-quality coffee, ergonomic designer furniture, and a top technical setup (Apple hardware + XXL screens).
• Regular Team Events: Joint activities such as surfing or a boat trip strengthen team spirit and make your time with us even better.
• Paid Lunches: We take care of your physical well-being.
• Workation: In early 2027, we will travel to Cape Town together for 2 weeks.

About Us

Sunpeak Capital emerged from the shared vision of Konstantin and Jan. Before founding the company, they were the first two employees of the fintech scale-up Cloover, which finances PV systems. For this, they built up the German market and scaled the partner network to over 200 installation companies. During this time, they recognized the potential created when capital is specifically directed into sustainable energy projects.

In early 2025, they founded Sunpeak Capital – fully bootstrapped and already profitable after two months. Their drive: to leverage the mechanisms of the capital market to accelerate the expansion of renewable energies and enable investors to achieve real returns with real impact.

We look forward to your application!
