Launched in 2021 with a simple yet bold mission, Flink set out to give people back their most valuable resource: time. We didn't just join the quick commerce race, we defined its potential. By enabling customers to order from a curated selection of over 3,000 groceries and household essentials through our user-centric app, we deliver what people need in minutes. We have fundamentally shifted the retail landscape across Germany and the Netherlands, while embedding sustainability into our core through an all-electric delivery fleet, recyclable packaging, and a focus on reducing food waste.

Today, Flink has evolved from a disruptive startup into a resilient and sustainable powerhouse. In an industry defined by rapid change, we’ve mastered the balance of hyper-efficiency and massive scale. With a network of around 160 hubs, we now bring the Flink experience to more than 22 million people, making us an integral part of the urban infrastructure. This impact is driven by a dedicated team of more than 10,000 colleagues, including a fully employed rider fleet that serves as the backbone of our operations. By generating over €550m in revenue in 2025, we have proven that our model is not only desirable but financially formidable. 

Having built a proven foundation, we are now shifting from establishing our presence to accelerating our impact. Backed by prestigious partners like Prosus, Mubadala, Bond, DoorDash, Btomorrow Ventures and REWE, and fueled by fresh investment, we are entering our next major growth phase. We are thinking bigger, expanding our footprint, and refining every link in our value chain. 

Our culture is defined by a shared bias for action and the commitment to being 1% better every day. We take ownership, stay close to the frontline, and support one another to ensure we never let another Flinker fail. We celebrate diversity and believe that our multicultural team is our greatest competitive advantage. 

Are you ready to shape the future of quick commerce with us?

In this internship, you will be at the heart of our strategy to maximize Customer Lifetime Value. 

You'll dive deep into our data to uncover what keeps our customers loyal and identify the key levers to drive long-term retention. Your work will directly influence key business decisions and help shape the future of Flink's customer retention strategy.
