More Growth Through Strategic Digital Marketing
Many startups invest in growth without knowing which channels align with their business model, how their digital value creation can work, or which metrics are truly relevant.
We take a different approach: We work with you to plan how digital marketing can contribute to growth and your growth goals, and if needed, we take over full coordination as your external marketing department. Before we get started, we honestly assess whether we see realistic potential for your startup. If so, we build a foundation that scales with you.

The Critical Challenges Facing Startups in the Growth Phase
Too much going on at once, not enough structure
Does this sound familiar to you?
No clear idea of which digital channels are truly effective
The website doesn't reflect how far along your product is
Investing in marketing, but qualified leads are not coming in
The reports show activity, but no figures that would convince investors
Operational needs, but no resources for a full team
Why Traditional Marketing Approaches Fail for Startups
What startups really need is a digital setup that scales with them: ready to go quickly, measurable at every step, and consistently focused on the target audience—whether that’s customers, partners, or investors.
How we support startups
External digital marketing department
If needed, we can step in as interim managers to handle all aspects of your digital marketing: taking strategic responsibility, managing day-to-day operations, and ensuring clear communication both internally and externally. This is particularly valuable if you don’t yet have your own marketing team or if you need additional capacity on short notice during a growth phase without having to establish permanent structures.
Digital value creation from the very beginning
Before a single campaign goes live, we work together to address the key questions, define relevant KPIs for all stakeholders, and develop a strategy and project plan for the first 12 months.
This planning of digital value creation serves as the starting point for every collaboration and replaces gut feelings with a solid foundation.
Identification of opportunities for scaling
Scalable technical infrastructure
From day one, we build a transparent, scalable technical foundation: accurate tracking, GDPR-compliant data collection, and real-time dashboards that keep you informed about the performance of your campaigns at all times.
Financial and Media Planning
Stakeholder Reports
We prepare your marketing data so that it is clear and meaningful to external stakeholders— whether it’s growth metrics, CAC, lead quality, or a breakdown of channel performance.
And we take it a step further: Together, we create clear data structures and scalable reporting systems that reveal your startup’s full growth potential. For investors making decisions in the next funding round, it’s not activity reports that matter—it’s reliable data that builds trust and demonstrates your scalability.
Whether it's seed funding, Series A, or beyond: We help you build the data foundation that not only prepares you for future funding rounds but also actively secures them.
Rely on proven expertise

helped osapiens achieve unicorn status
osapiens develops cloud-based software solutions for sustainability reporting and ESG management and now has over 1,300 customers worldwide. As the Mannheim-based company accelerated its international expansion, it needed a digital infrastructure that could keep pace with this growth.

The result: In January 2026, following a $100 million funding round, the company reached a market value of $1 billion, thereby achieving the coveted unicorn status.

Achieve a successful funding round with foodforecast
foodforecast is revolutionizing the food industry with AI-powered sales forecasts and automated ordering processes. Since 2021, we have been supporting the Cologne-based tech startup on its journey—from its first website to successful funding rounds and international expansion.
From the very beginning, our role went beyond traditional agency work: We built a robust digital infrastructure that enabled foodforecast to focus on its core business. The tracking and marketing automation solutions we developed laid the groundwork for data-driven decisions at every stage of growth.
The result: foodforecast now uses its technology in thousands of stores, has automated millions of orders, and secured a funding round of three million euros in 2024. The next round followed in February 2026: an additional eight million euros to support the company’s sustainable growth.
With Partner & Söhne , we had someone right from the start who not only advised us, but really supported us. They took us from a German website to an international platform in five languages, opened up LinkedIn as a sales channel and set up lead tracking with HubSpot. They supported us digitally in every phase - whether it was founding, financing or scaling.
